ration Zinc promotes liquid-liquid phase separation of tau protein [Protein Structure and Folding] By feedproxy.google.com Published On :: 2020-05-01T00:06:09-07:00 Tau is a microtubule-associated protein that plays a major role in Alzheimer's disease (AD) and other tauopathies. Recent reports indicate that, in the presence of crowding agents, tau can undergo liquid–liquid phase separation (LLPS), forming highly dynamic liquid droplets. Here, using recombinantly expressed proteins, turbidimetry, fluorescence microscopy imaging, and fluorescence recovery after photobleaching (FRAP) assays, we show that the divalent transition metal zinc strongly promotes this process, shifting the equilibrium phase boundary to lower protein or crowding agent concentrations. We observed no tau LLPS-promoting effect for any other divalent transition metal ions tested, including Mn2+, Fe2+, Co2+, Ni2+, and Cu2+. We also demonstrate that multiple zinc-binding sites on tau are involved in the LLPS-promoting effect and provide insights into the mechanism of this process. Zinc concentration is highly elevated in AD brains, and this metal ion is believed to be an important player in the pathogenesis of this disease. Thus, the present findings bring a new dimension to understanding the relationship between zinc homeostasis and the pathogenic process in AD and related neurodegenerative disorders. Full Article
ration Synergy in North Africa: Furthering Cooperation By feedproxy.google.com Published On :: Mon, 20 Jan 2020 15:57:54 +0000 21 January 2020 Discussions of North African integration have evoked ideas of a shared identity and a common destiny in the region. However, recent attempts to build regional blocs in North Africa have been unsuccessful. This paper examines the benefits of a ‘synergistic’ approach to North African cooperation.

Photo: Getty Images. SummaryNorth African integration is not a new idea. However, countries in the region have so far struggled to form a cohesive bloc with deep political, economic and social ties. Political instability has effectively deprioritized North African integration. A focus on thematic (political, economic and security) ‘synergies’ may provide a better framework for cooperation than seeking opportunities for all-encompassing ‘deep’ and ‘comprehensive’ integration.Governments of North Africa dedicate considerable resources to domestic security. Much of their efforts are conducted at the national-level and directed towards threats from terrorists, insurgents and militias. Improved security cooperation would achieve better outcomes and economies of scale, including efforts to tackle human trafficking.A new generation of jihadis has emerged in North Africa since 2011. Nearly 27 per cent of the 30,000 fighters who travelled to Syria are from the Maghreb. While government counterterrorism operations have been effective, countries have failed to address the root causes of radicalization.Border economies have suffered as a consequence of a security focus on terrorism and smuggling, which has rendered many previously accepted cross-border trade activities illegal. States have struggled to provide alternative livelihoods for those who have lost this source of income. Border forces tend to lack the right combination of capacity, training and equipment to secure borders and often resort to heavy-handed tactics.New thinking is required to develop a more human-centric and proactive approach to migration issues in the region, which continues to witness huge flows of migrants. The migration policy of Morocco, introduced through legislation in 2014, could be a model for North Africa.The countries of North Africa have varying economic profiles, ranging from economically diverse Morocco to oil-and-gas-dependant Libya. However, they all face similar challenges including unemployment (particularly among the young), poor public-service delivery, low FDI levels, an oversized public sector, ineffective tax collection, and high informality.Fostering entrepreneurship and the development of small and medium-sized enterprises (SMEs) are priorities for North African countries, particularly regarding job creation. Regulatory cooperation – such as harmonizing SME definitions, legislation and support institutions – across North Africa is an obvious area where further integration would encourage the development of start-ups and small businesses.With the advent of the fourth industrial revolution, North African governments must address their technological gaps and work to improve public–private cooperation. In some sectors, such as the fintech industry, North African countries can build upon nascent synergies that have developed organically, such as those of start-up incubators and angel investors that work across the region.Renewables, particularly solar energy production, are a promising development for North Africa. While regional initiatives, such as Desertec, have stalled due to political differences between countries, the sector has witnessed exponential growth in Tunisia, Egypt and Morocco, where the involvement of the private sector has proved successful.

ration Three distinct glycosylation pathways are involved in the decoration of Lactococcus lactis cell wall glycopolymers [Microbiology] By feedproxy.google.com Published On :: 2020-04-17T00:06:05-07:00 Extracytoplasmic sugar decoration of glycopolymer components of the bacterial cell wall contributes to their structural diversity. Typically, the molecular mechanism that underpins such a decoration process involves a three-component glycosylation system (TGS) represented by an undecaprenyl-phosphate (Und-P) sugar-activating glycosyltransferase (Und-P GT), a flippase, and a polytopic glycosyltransferase (PolM GT) dedicated to attaching sugar residues to a specific glycopolymer. Here, using bioinformatic analyses, CRISPR-assisted recombineering, structural analysis of cell wall–associated polysaccharides (CWPS) through MALDI-TOF MS and methylation analysis, we report on three such systems in the bacterium Lactococcus lactis. On the basis of sequence similarities, we first identified three gene pairs, csdAB, csdCD, and csdEF, each encoding an Und-P GT and a PolM GT, as potential TGS component candidates. Our experimental results show that csdAB and csdCD are involved in Glc side-chain addition on the CWPS components rhamnan and polysaccharide pellicle (PSP), respectively, whereas csdEF plays a role in galactosylation of lipoteichoic acid (LTA). We also identified a potential flippase encoded in the L. lactis genome (llnz_02975, cflA) and confirmed that it participates in the glycosylation of the three cell wall glycopolymers rhamnan, PSP, and LTA, thus indicating that its function is shared by the three TGSs. Finally, we observed that glucosylation of both rhamnan and PSP can increase resistance to bacteriophage predation and that LTA galactosylation alters L. lactis resistance to bacteriocin.

Photo: Getty Images. SummaryThe United States’ transatlantic allies need to appreciate how its global leadership is changing and what this means for their interests, and respond accordingly. Notions of US decline have been overstated, but the country is not going to play the same international role in the future that it has previously.As the United States’ international engagement changes, Canada and Europe should increase coordination with it to prevent power vacuums from emerging. The transatlantic allies should work together to build greater links at all stages of the policy process, from perceptions of threat, prioritization, analysis, threat definition and policy formation to implementation and action. As the United States’ capabilities adapt to its changed circumstances and role, so too must those of its allies. This adjustment must go far beyond military aspects to enhancing diplomatic, energy, economic, intelligence and other resources.In addition to the challenges around differing interests, priorities and capabilities inherent in any alliance, Europe appears to have lost its confidence. In part this is due to its growing disengagement and introspection. But Europe retains huge potential for influence if it uses its resources effectively. There is much that European states can do, individually and together, to take more control over advancing their strategic interests. Equally, by working together they can do much to nudge the United States in helpful directions to support the mutual interests of all parties.The conversation on reforming global institutions such as the IMF must move beyond the need for change per se towards articulating the actual shape of such changes. Europe and Canada will likely need to push the United States into accepting reform of these institutions to better reflect today’s reality and tomorrow’s challenges. Global institutions need more diversified leaderships if they are to ensure their long-term legitimacy and influence. This will be difficult to push through politically in the United States, but by working with new regional and global powers to propose reforms, Europe and Canada can help find an acceptable solution.The use of ad hoc coalitions does not necessarily damage the efficacy of broader consensus institutions such as NATO. In fact, flexible coalitions may often be desirable when solutions to new challenges need to be developed and agreed quickly.Canada and Europe should consider partnering with other actors besides the United States where necessary. This may be expedient for meeting individual objectives, and would have the secondary benefit of demonstrating to emerging powers that the West does not exclude cooperation with others out of an arbitrary loyalty to the United States.Europe needs to appreciate the potentially dire consequences of failing to adapt to changing US leadership and an increasingly complex world. There is a real chance that the European project could unravel in the next few years due to external and internal pressures. While many European policy-makers display an understanding of these challenges in private, in public there is little appetite for taking the decisions necessary to bring long-term stability to the continent.

ration The Hurdles to Developing a COVID-19 Vaccine: Why International Cooperation is Needed By feedproxy.google.com Published On :: Thu, 23 Apr 2020 09:26:36 +0000 23 April 2020 Professor David Salisbury CB Associate Fellow, Global Health Programme LinkedIn Dr Champa Patel Director, Asia-Pacific Programme @patel_champa While the world pins its hopes on vaccines to prevent COVID-19, there are scientific, regulatory and market hurdles to overcome. Furthermore, with geopolitical tensions and nationalistic approaches, there is a high risk that the most vulnerable will not get the life-saving interventions they need. 2020-04-23-Covid-Vaccine.jpg A biologist works on the virus inactivation process in Belo Horizonte, Brazil on 24 March 2020. The Brazilian Ministry of Health convened The Technological Vaccine Center to conduct research on COVID-19 in order to diagnose, test and develop a vaccine. Photo: Getty Images. On 10 January 2020, Chinese scientists released the sequence of the COVID-19 genome on the internet. This provided the starting gun for scientists around the world to start developing vaccines or therapies. With at least 80 different vaccines in development, many governments are pinning their hopes on a quick solution. However, there are many hurdles to overcome. Vaccine developmentFirstly, vaccine development is normally a very long process to ensure vaccines are safe and effective before they are used. Safety is not a given: a recent dengue vaccine caused heightened disease in vaccinated children when they later were exposed to dengue, while Respiratory Syncytial Virus vaccine caused the same problem. Nor is effectiveness a given. Candidate vaccines that use novel techniques where minute fragments of the viruses’ genetic code are either injected directly into humans or incorporated into a vaccine (as is being pursued, or could be pursued for COVID-19) have higher risks of failure simply because they haven’t worked before. For some vaccines, we know what levels of immunity post-vaccination are likely to be protective. This is not the case for coronavirus. Clinical trials will have to be done for efficacy. This is not optional – regulators will need to know extensive testing has taken place before licencing any vaccine. Even if animal tests are done in parallel with early human tests, the remainder of the process is still lengthy. There is also great interest in the use of passive immunization, whereby antibodies to SARS-CoV-2 (collected from people who have recovered from infection or laboratory-created) are given to people who are currently ill. Antivirals may prove to be a quicker route than vaccine development, as the testing requirements would be shorter, manufacturing may be easier and only ill people would need to be treated, as opposed to all at-risk individuals being vaccinated.Vaccine manufacturingDevelopers, especially small biotechs, will have to make partnerships with large vaccine manufacturers in order to bring products to market. One notorious bottleneck in vaccine development is getting from proof-of-principle to commercial development: about 95 per cent of vaccines fail at this step. Another bottleneck is at the end of production. The final stages of vaccine production involve detailed testing to ensure that the vaccine meets the necessary criteria and there are always constraints on access to the technologies necessary to finalize the product. Only large vaccine manufacturers have these capacities. There is a graveyard of failed vaccine candidates that have not managed to pass through this development and manufacturing process.Another consideration is adverse or unintended consequences. Highly specialized scientists may have to defer their work on other new vaccines to work on COVID-19 products and production of existing products may have to be set aside, raising the possibility of shortages of other essential vaccines. Cost is another challenge. Vaccines for industrialized markets can be very lucrative for pharmaceutical companies, but many countries have price caps on vaccines. Important lessons have been learned from the 2009 H1N1 flu pandemic when industrialized countries took all the vaccines first. Supplies were made available to lower-income countries at a lower price but this was much later in the evolution of the pandemic. For the recent Ebola outbreaks, vaccines were made available at low or no cost. Geopolitics may also play a role. Should countries that manufacture a vaccine share it widely with other countries or prioritize their own populations first? It has been reported that President Trump attempted to purchase CureVac, a German company with a candidate vaccine. There are certainly precedents for countries prioritizing their own populations. With H1N1 flu in 2009, the Australian Government required a vaccine company to meet the needs of the Australian population first. Vaccine distributionGlobal leadership and a coordinated and coherent response will be needed to ensure that any vaccine is distributed equitably. There have been recent calls for a G20 on health, but existing global bodies such as the Coalition for Epidemic Preparedness Innovations (CEPI) and GAVI are working on vaccines and worldwide access to them. Any new bodies should seek to boost funding for these entities so they can ensure products reach the most disadvantaged. While countries that cannot afford vaccines may be priced out of markets, access for poor, vulnerable or marginalized peoples, whether in developed or developing countries, is of concern. Developing countries are at particular risk from the impacts of COVID-19. People living in conflict-affected and fragile states – whether they are refugees or asylum seekers, internally displaced or stateless, or in detention facilities – are at especially high risk of devastating impacts. Mature economies will also face challenges. Equitable access to COVID-19 vaccine will be challenging where inequalities and unequal access to essential services have been compromised within some political systems. The need for global leadership There is an urgent need for international coordination on COVID-19 vaccines. While the WHO provides technical support and UNICEF acts as a procurement agency, responding to coronavirus needs clarity of global leadership that arches over national interests and is capable of mobilizing resources at a time when economies are facing painful recessions. We see vaccines as a salvation but remain ill-equipped to accelerate their development.While everyone hopes for rapid availability of safe, effective and affordable vaccines that will be produced in sufficient quantities to meet everyone’s needs, realistically, we face huge hurdles.

At the same time, the organization is reliant on an international order that the current coronavirus crisis is, arguably, disrupting: as containment measures become more important in stemming the spread of the virus, the temptation to implement protectionist policies is increasing among nations. For example, the UK did not participate in an EU scheme to buy PPE and Germany has accused the US of ‘piracy’ after it reportedly diverted a shipment of masks intended for Berlin. Elsewhere, despite rhetorical commitments from the G7 and G20, a detailed plan for a comprehensive international response has not been forthcoming. The panel will discuss issues of coordination and cooperation in the international response to COVID-19. Have global trends prior to the outbreak contributed to the slow and disjointed international response? How has the pandemic exposed fissures in the extent to which nations are willing to cooperate? And what is the capacity of international organizations such as the WHO to coordinate a concerted transnational response and what could the implications be for the future of globalization and the international liberal order?This event is open to Chatham House Members.

ration The cytochrome P450 enzyme CYP24A1 increases proliferation of mutant KRAS-dependent lung adenocarcinoma independent of its catalytic activity [Cell Biology] By feedproxy.google.com Published On :: 2020-05-01T00:06:09-07:00 We previously reported that overexpression of cytochrome P450 family 24 subfamily A member 1 (CYP24A1) increases lung cancer cell proliferation by activating RAS signaling and that CYP24A1 knockdown inhibits tumor growth. However, the mechanism of CYP24A1-mediated cancer cell proliferation remains unclear. Here, we conducted cell synchronization and biochemical experiments in lung adenocarcinoma cells, revealing a link between CYP24A1 and anaphase-promoting complex (APC), a key cell cycle regulator. We demonstrate that CYP24A1 expression is cell cycle–dependent; it was higher in the G2-M phase and diminished upon G1 entry. CYP24A1 has a functional destruction box (D-box) motif that allows binding with two APC adaptors, CDC20-homologue 1 (CDH1) and cell division cycle 20 (CDC20). Unlike other APC substrates, however, CYP24A1 acted as a pseudo-substrate, inhibiting CDH1 activity and promoting mitotic progression. Conversely, overexpression of a CYP24A1 D-box mutant compromised CDH1 binding, allowing CDH1 hyperactivation, thereby hastening degradation of its substrates cyclin B1 and CDC20, and accumulation of the CDC20 substrate p21, prolonging mitotic exit. These activities also occurred with a CYP24A1 isoform 2 lacking the catalytic cysteine (Cys-462), suggesting that CYP24A1's oncogenic potential is independent of its catalytic activity. CYP24A1 degradation reduced clonogenic survival of mutant KRAS-driven lung cancer cells, and calcitriol treatment increased CYP24A1 levels and tumor burden in Lsl-KRASG12D mice. These results disclose a catalytic activity-independent growth-promoting role of CYP24A1 in mutant KRAS-driven lung cancer. This suggests that CYP24A1 could be therapeutically targeted in lung cancers in which its expression is high. Full Article
ration SUMOylation of the transcription factor ZFHX3 at Lys-2806 requires SAE1, UBC9, and PIAS2 and enhances its stability and function in cell proliferation [Protein Synthesis and Degradation] By feedproxy.google.com Published On :: 2020-05-08T03:41:14-07:00 SUMOylation is a posttranslational modification (PTM) at a lysine residue and is crucial for the proper functions of many proteins, particularly of transcription factors, in various biological processes. Zinc finger homeobox 3 (ZFHX3), also known as AT motif-binding factor 1 (ATBF1), is a large transcription factor that is active in multiple pathological processes, including atrial fibrillation and carcinogenesis, and in circadian regulation and development. We have previously demonstrated that ZFHX3 is SUMOylated at three or more lysine residues. Here, we investigated which enzymes regulate ZFHX3 SUMOylation and whether SUMOylation modulates ZFHX3 stability and function. We found that SUMO1, SUMO2, and SUMO3 each are conjugated to ZFHX3. Multiple lysine residues in ZFHX3 were SUMOylated, but Lys-2806 was the major SUMOylation site, and we also found that it is highly conserved among ZFHX3 orthologs from different animal species. Using molecular analyses, we identified the enzymes that mediate ZFHX3 SUMOylation; these included SUMO1-activating enzyme subunit 1 (SAE1), an E1-activating enzyme; SUMO-conjugating enzyme UBC9 (UBC9), an E2-conjugating enzyme; and protein inhibitor of activated STAT2 (PIAS2), an E3 ligase. Multiple analyses established that both SUMO-specific peptidase 1 (SENP1) and SENP2 deSUMOylate ZFHX3. SUMOylation at Lys-2806 enhanced ZFHX3 stability by interfering with its ubiquitination and proteasomal degradation. Functionally, Lys-2806 SUMOylation enabled ZFHX3-mediated cell proliferation and xenograft tumor growth of the MDA-MB-231 breast cancer cell line. These findings reveal the enzymes involved in, and the functional consequences of, ZFHX3 SUMOylation, insights that may help shed light on ZFHX3's roles in various cellular and pathophysiological processes.

ration Thioredoxin regulates human mercaptopyruvate sulfurtransferase at physiologically-relevant concentrations [Enzymology] By feedproxy.google.com Published On :: 2020-05-08T03:41:14-07:00 3-Mercaptopyruvate sulfur transferase (MPST) catalyzes the desulfuration of 3-mercaptopyruvate (3-MP) and transfers sulfane sulfur from an enzyme-bound persulfide intermediate to thiophilic acceptors such as thioredoxin and cysteine. Hydrogen sulfide (H2S), a signaling molecule implicated in many physiological processes, can be released from the persulfide product of the MPST reaction. Two splice variants of MPST, differing by 20 amino acids at the N terminus, give rise to the cytosolic MPST1 and mitochondrial MPST2 isoforms. Here, we characterized the poorly-studied MPST1 variant and demonstrated that substitutions in its Ser–His–Asp triad, proposed to serve a general acid–base role, minimally affect catalytic activity. We estimated the 3-MP concentration in murine liver, kidney, and brain tissues, finding that it ranges from 0.4 μmol·kg−1 in brain to 1.4 μmol·kg−1 in kidney. We also show that N-acetylcysteine, a widely-used antioxidant, is a poor substrate for MPST and is unlikely to function as a thiophilic acceptor. Thioredoxin exhibits substrate inhibition, increasing the KM for 3-MP ∼15-fold compared with other sulfur acceptors. Kinetic simulations at physiologically-relevant substrate concentrations predicted that the proportion of sulfur transfer to thioredoxin increases ∼3.5-fold as its concentration decreases from 10 to 1 μm, whereas the total MPST reaction rate increases ∼7-fold. The simulations also predicted that cysteine is a quantitatively-significant sulfane sulfur acceptor, revealing MPST's potential to generate low-molecular-weight persulfides. We conclude that the MPST1 and MPST2 isoforms are kinetically indistinguishable and that thioredoxin modulates the MPST-catalyzed reaction in a physiologically-relevant concentration range.

ration The recalibration of Chinese assertiveness: China's responses to the Indo-Pacific challenge By feedproxy.google.com Published On :: Wed, 08 Jan 2020 11:14:26 +0000 8 January 2020 , Volume 96, Number 1 Read online Feng Liu In response to the changing geopolitical landscape in Asia, both China and the United States attempt to alter the regional order in their own favour, both in the economic and security realms. This article shows how diverging views on future arrangements are leading to strategic shifts and increasing tension between these two Great Powers. As part of its quest for Great-Power status, China has been actively pushing its regional initiatives such as the Belt and Road Initiative (BRI) and the Asian Infrastructure Investment Bank (AIIB), as well as adopting assertive security policies towards its neighbours. In contrast, in order to counter China's growing influence America's regional strategy is undergoing a subtle shift from ‘rebalancing to Asia’ to focusing on the ‘Indo-Pacific’ region. However, amid an intensifying trade war and other challenges facing the region, China has chosen to moderate its proactive foreign policy-orientation in the past few years. In particular, China has made attempts to downplay its domestic rhetoric, rebuild strategic relationship with India and Japan, and to reassure ASEAN states in the South China Sea. In response to the Indo-Pacific strategy, it would be more effective for China to articulate a more inclusive regional vision and promote an institutional framework that also accommodates a US presence in the region.

ration Non-traditional security cooperation between China and south-east Asia: implications for Indo-Pacific geopolitics By feedproxy.google.com Published On :: Wed, 08 Jan 2020 11:17:30 +0000 8 January 2020 , Volume 96, Number 1 Read online Xue Gong The ‘free and open Indo-Pacific’ (FOIP) strategy, actively promoted by the United States with support from its allies and partners, is a significant geopolitical response to China's growing power and expanding influence in Asia and beyond. Beijing has adopted various new strategies to cope with the challenges related to FOIP. One of these strategies is to secure a robust relationship with south-east Asia in order to make these regional states either neutral to or less supportive of the Indo-Pacific vision. In addition to economic statecraft and soft power, Beijing believes that it can also tap into the domain of non-traditional security (NTS) to strengthen relations with this region to position itself better in the intensifying regional geopolitical competition. The article addresses the following question: what is the impact of China's NTS cooperation with south-east Asia on Beijing's geopolitical rivalry with other major powers in the Indo-Pacific region? The article argues that China's NTS cooperation with south-east Asian countries may help China maintain its geopolitical standing in the region, but it is unlikely to lead to any dramatic increase of China's strategic influence in the region. This essentially means that Beijing may be able to prevent ASEAN or most ASEAN member states from lending substantive and strong support to the Indo-Pacific construct, but it will not be able to stop ASEAN states from supporting some elements of the FOIP.

President Zelenskyy, who came to power in May 2019, promised to end the war with Russia and bring peace to Ukraine.Since assuming office, Zelenskyy has managed to revive the Normandy Format talks, complete military disengagement at three points along the line of contact and negotiate the release of over a hundred Ukrainians held as prisoners of war in Russia. However, ceasefire violations continue to occur frequently.Looking at the origins of the armed conflict in Donbas and the region’s economic role in Ukraine’s economy, this event discusses the prospects for conflict resolution. Do the recent events signify an opportunity for peace? Does Zelenskyy have a viable plan for re-integrating Donbas or will the region be cut off from mainland Ukraine for the foreseeable future?The speakers assess the strategy and track record of the Ukrainian government and its Western allies in bringing parts of the occupied Donbas under Kyiv’s control. They also review possible policy implications of the COVID-19 pandemic for the conflict.

At the same time, the organization is reliant on an international order that the current coronavirus crisis is, arguably, disrupting: as containment measures become more important in stemming the spread of the virus, the temptation to implement protectionist policies is increasing among nations. For example, the UK did not participate in an EU scheme to buy PPE and Germany has accused the US of ‘piracy’ after it reportedly diverted a shipment of masks intended for Berlin. Elsewhere, despite rhetorical commitments from the G7 and G20, a detailed plan for a comprehensive international response has not been forthcoming. The panel will discuss issues of coordination and cooperation in the international response to COVID-19. Have global trends prior to the outbreak contributed to the slow and disjointed international response? How has the pandemic exposed fissures in the extent to which nations are willing to cooperate? And what is the capacity of international organizations such as the WHO to coordinate a concerted transnational response and what could the implications be for the future of globalization and the international liberal order?This event is open to Chatham House Members.

Estimates from June 2019 have placed the number of migrants at nearly double of what they were in 2018 with the increase in numbers stemming from a lack of economic opportunity combined with a rise in crime and insecurity in the region. The impacts of migration can already be felt within the affected states as the exodus has played a significant role in weakening labour markets and contributing to a ‘brain drain’ in the region. It has also played an increasingly active role in the upcoming US presidential election with some calling for more security on the border to curb immigration while others argue that a more effective strategy is needed to address the sources of migration. What are the core causes of Central American migration and how have the US, Central American and now also Mexican governments facilitated and deterred migration from the region? Can institutions be strengthened to alleviate the causes of migration? And what possible policy alternatives and solutions are there that could alleviate the pressures individuals and communities feel to migrate? Anita Isaacs, professor of Political Science at Haverford College and co-director of the Migration Encounters Project, and Juan Ricard Ortega, principal advisor for Central America at the Inter-American Development Bank, will join us for a discussion on the core drivers of migration within and across Central America.Attendance at this event is by invitation only.

Furthermore, with geopolitical tensions and nationalistic approaches, there is a high risk that the most vulnerable will not get the life-saving interventions they need. 2020-04-23-Covid-Vaccine.jpg A biologist works on the virus inactivation process in Belo Horizonte, Brazil on 24 March 2020. The Brazilian Ministry of Health convened The Technological Vaccine Center to conduct research on COVID-19 in order to diagnose, test and develop a vaccine. Photo: Getty Images. On 10 January 2020, Chinese scientists released the sequence of the COVID-19 genome on the internet. This provided the starting gun for scientists around the world to start developing vaccines or therapies. With at least 80 different vaccines in development, many governments are pinning their hopes on a quick solution. However, there are many hurdles to overcome. Vaccine developmentFirstly, vaccine development is normally a very long process to ensure vaccines are safe and effective before they are used. Safety is not a given: a recent dengue vaccine caused heightened disease in vaccinated children when they later were exposed to dengue, while Respiratory Syncytial Virus vaccine caused the same problem. Nor is effectiveness a given. Candidate vaccines that use novel techniques where minute fragments of the viruses’ genetic code are either injected directly into humans or incorporated into a vaccine (as is being pursued, or could be pursued for COVID-19) have higher risks of failure simply because they haven’t worked before. For some vaccines, we know what levels of immunity post-vaccination are likely to be protective. This is not the case for coronavirus. Clinical trials will have to be done for efficacy. This is not optional – regulators will need to know extensive testing has taken place before licencing any vaccine. Even if animal tests are done in parallel with early human tests, the remainder of the process is still lengthy. There is also great interest in the use of passive immunization, whereby antibodies to SARS-CoV-2 (collected from people who have recovered from infection or laboratory-created) are given to people who are currently ill. Antivirals may prove to be a quicker route than vaccine development, as the testing requirements would be shorter, manufacturing may be easier and only ill people would need to be treated, as opposed to all at-risk individuals being vaccinated.Vaccine manufacturingDevelopers, especially small biotechs, will have to make partnerships with large vaccine manufacturers in order to bring products to market. One notorious bottleneck in vaccine development is getting from proof-of-principle to commercial development: about 95 per cent of vaccines fail at this step. Another bottleneck is at the end of production. The final stages of vaccine production involve detailed testing to ensure that the vaccine meets the necessary criteria and there are always constraints on access to the technologies necessary to finalize the product. Only large vaccine manufacturers have these capacities. There is a graveyard of failed vaccine candidates that have not managed to pass through this development and manufacturing process.Another consideration is adverse or unintended consequences. Highly specialized scientists may have to defer their work on other new vaccines to work on COVID-19 products and production of existing products may have to be set aside, raising the possibility of shortages of other essential vaccines. Cost is another challenge. Vaccines for industrialized markets can be very lucrative for pharmaceutical companies, but many countries have price caps on vaccines. Important lessons have been learned from the 2009 H1N1 flu pandemic when industrialized countries took all the vaccines first. Supplies were made available to lower-income countries at a lower price but this was much later in the evolution of the pandemic. For the recent Ebola outbreaks, vaccines were made available at low or no cost. Geopolitics may also play a role. Should countries that manufacture a vaccine share it widely with other countries or prioritize their own populations first? It has been reported that President Trump attempted to purchase CureVac, a German company with a candidate vaccine. There are certainly precedents for countries prioritizing their own populations. With H1N1 flu in 2009, the Australian Government required a vaccine company to meet the needs of the Australian population first. Vaccine distributionGlobal leadership and a coordinated and coherent response will be needed to ensure that any vaccine is distributed equitably. There have been recent calls for a G20 on health, but existing global bodies such as the Coalition for Epidemic Preparedness Innovations (CEPI) and GAVI are working on vaccines and worldwide access to them. Any new bodies should seek to boost funding for these entities so they can ensure products reach the most disadvantaged. While countries that cannot afford vaccines may be priced out of markets, access for poor, vulnerable or marginalized peoples, whether in developed or developing countries, is of concern. Developing countries are at particular risk from the impacts of COVID-19. People living in conflict-affected and fragile states – whether they are refugees or asylum seekers, internally displaced or stateless, or in detention facilities – are at especially high risk of devastating impacts. Mature economies will also face challenges. Equitable access to COVID-19 vaccine will be challenging where inequalities and unequal access to essential services have been compromised within some political systems. The need for global leadership There is an urgent need for international coordination on COVID-19 vaccines. While the WHO provides technical support and UNICEF acts as a procurement agency, responding to coronavirus needs clarity of global leadership that arches over national interests and is capable of mobilizing resources at a time when economies are facing painful recessions. We see vaccines as a salvation but remain ill-equipped to accelerate their development.While everyone hopes for rapid availability of safe, effective and affordable vaccines that will be produced in sufficient quantities to meet everyone’s needs, realistically, we face huge hurdles.

ration Lipid rafts and neurodegeneration: structural and functional roles in physiologic aging and neurodegenerative diseases [Thematic Reviews] By feedproxy.google.com Published On :: 2020-05-01T00:05:27-07:00 Lipid rafts are small, dynamic membrane areas characterized by the clustering of selected membrane lipids as the result of the spontaneous separation of glycolipids, sphingolipids, and cholesterol in a liquid-ordered phase. The exact dynamics underlying phase separation of membrane lipids in the complex biological membranes are still not fully understood. Nevertheless, alterations in the membrane lipid composition affect the lateral organization of molecules belonging to lipid rafts. Neural lipid rafts are found in brain cells, including neurons, astrocytes, and microglia, and are characterized by a high enrichment of specific lipids depending on the cell type. These lipid rafts seem to organize and determine the function of multiprotein complexes involved in several aspects of signal transduction, thus regulating the homeostasis of the brain. The progressive decline of brain performance along with physiological aging is at least in part associated with alterations in the composition and structure of neural lipid rafts. In addition, neurodegenerative conditions, such as lysosomal storage disorders, multiple sclerosis, and Parkinson’s, Huntington’s, and Alzheimer’s diseases, are frequently characterized by dysregulated lipid metabolism, which in turn affects the structure of lipid rafts. Several events underlying the pathogenesis of these diseases appear to depend on the altered composition of lipid rafts. Thus, the structure and function of lipid rafts play a central role in the pathogenesis of many common neurodegenerative diseases. Full Article
ration The recalibration of Chinese assertiveness: China's responses to the Indo-Pacific challenge By feedproxy.google.com Published On :: Wed, 08 Jan 2020 11:14:26 +0000 8 January 2020 , Volume 96, Number 1 Read online Feng Liu In response to the changing geopolitical landscape in Asia, both China and the United States attempt to alter the regional order in their own favour, both in the economic and security realms. This article shows how diverging views on future arrangements are leading to strategic shifts and increasing tension between these two Great Powers. As part of its quest for Great-Power status, China has been actively pushing its regional initiatives such as the Belt and Road Initiative (BRI) and the Asian Infrastructure Investment Bank (AIIB), as well as adopting assertive security policies towards its neighbours. In contrast, in order to counter China's growing influence America's regional strategy is undergoing a subtle shift from ‘rebalancing to Asia’ to focusing on the ‘Indo-Pacific’ region. However, amid an intensifying trade war and other challenges facing the region, China has chosen to moderate its proactive foreign policy-orientation in the past few years. In particular, China has made attempts to downplay its domestic rhetoric, rebuild strategic relationship with India and Japan, and to reassure ASEAN states in the South China Sea. In response to the Indo-Pacific strategy, it would be more effective for China to articulate a more inclusive regional vision and promote an institutional framework that also accommodates a US presence in the region.

ration Non-traditional security cooperation between China and south-east Asia: implications for Indo-Pacific geopolitics By feedproxy.google.com Published On :: Wed, 08 Jan 2020 11:17:30 +0000 8 January 2020 , Volume 96, Number 1 Read online Xue Gong The ‘free and open Indo-Pacific’ (FOIP) strategy, actively promoted by the United States with support from its allies and partners, is a significant geopolitical response to China's growing power and expanding influence in Asia and beyond. Beijing has adopted various new strategies to cope with the challenges related to FOIP. One of these strategies is to secure a robust relationship with south-east Asia in order to make these regional states either neutral to or less supportive of the Indo-Pacific vision. In addition to economic statecraft and soft power, Beijing believes that it can also tap into the domain of non-traditional security (NTS) to strengthen relations with this region to position itself better in the intensifying regional geopolitical competition. The article addresses the following question: what is the impact of China's NTS cooperation with south-east Asia on Beijing's geopolitical rivalry with other major powers in the Indo-Pacific region? The article argues that China's NTS cooperation with south-east Asian countries may help China maintain its geopolitical standing in the region, but it is unlikely to lead to any dramatic increase of China's strategic influence in the region. This essentially means that Beijing may be able to prevent ASEAN or most ASEAN member states from lending substantive and strong support to the Indo-Pacific construct, but it will not be able to stop ASEAN states from supporting some elements of the FOIP.

The rise of China and tensions with the US are affecting bilateral relationships and traditional alliances in the region. Whether seen from the perspective of the Quad – Australia, India, Japan and the US – or the Indo-Pacific concept embraced by a wide range of countries but with no shared consensus on scope and objectives or with ASEAN who insists on the importance of its own centrality, the region is redefining and reconceptualising itself.With a diverse range of initiatives – including the Regional Comprehensive Economic Partnership (RCEP) and Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) – there are a plethora of regional agreements and institutional groupings that add further complexity.As the Bretton Woods architecture continues to be dominated by Western powers, China is also spearheading parallel governance initiatives such as the Asian Infrastructure Investment Bank (AIIB), the Belt and Road Initiative and the Shanghai Cooperation Organization (SCO) as a means of enhancing its geopolitical and geoeconomic influence.This one-day conference will focus on how such networks and alliances have been built, and sustained, in the Asia-Pacific region. In order to understand how new regional initiatives might open up opportunities for new forms of international cooperation, the conference will focus on the themes of cyber-technology and innovation, sustainable development and mitigating the impacts of climate change and new infrastructure initiatives. It will assess whether there is a zero-sum conflict between competing networks and agendas or whether a common approach can be developed.
