ER stress increases store-operated Ca2+ entry (SOCE) and augments basal insulin secretion in pancreatic beta cells [Molecular Bases of Disease]

Type 2 diabetes mellitus (T2DM) is characterized by impaired glucose-stimulated insulin secretion and increased peripheral insulin resistance. Unremitting endoplasmic reticulum (ER) stress can lead to beta-cell apoptosis and has been linked to type 2 diabetes. Although many studies have attempted to link ER stress and T2DM, the specific effects of ER stress on beta-cell function remain incompletely understood. To determine the interrelationship between ER stress and beta-cell function, here we treated insulin-secreting INS-1(832/13) cells or isolated mouse islets with the ER stress–inducer tunicamycin (TM). TM induced ER stress as expected, as evidenced by activation of the unfolded protein response. Beta cells treated with TM also exhibited concomitant alterations in their electrical activity and cytosolic free Ca2+ oscillations. As ER stress is known to reduce ER Ca2+ levels, we tested the hypothesis that the observed increase in Ca2+ oscillations occurred because of reduced ER Ca2+ levels and, in turn, increased store-operated Ca2+ entry. TM-induced cytosolic Ca2+ and membrane electrical oscillations were acutely inhibited by YM58483, which blocks store-operated Ca2+ channels. Significantly, TM-treated cells secreted increased insulin under conditions normally associated with only minimal release, e.g. 5 mm glucose, and YM58483 blocked this secretion. Taken together, these results support a critical role for ER Ca2+ depletion–activated Ca2+ current in mediating Ca2+-induced insulin secretion in response to ER stress.

Synergy in North Africa: Furthering Cooperation

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.

Summary

  • North 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.

The Future of US Global Leadership: Implications for Europe, Canada and Transatlantic Cooperation

Summary

  • The 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.

The Hurdles to Developing a COVID-19 Vaccine: Why International Cooperation is Needed

23 April 2020

Professor David Salisbury CB

Associate Fellow, Global Health Programme

Dr Champa Patel

Director, Asia-Pacific Programme
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

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 development

Firstly, 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 manufacturing

Developers, 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 distribution

Global 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.

Chair: Dr Champa Patel, Director, Asia-Pacific Programme, Chatham House

 

As a body with a relatively small operating budget and no formal mechanisms, or authority, to sanction member states that fail to comply with its guidance, the World Health Organization has been limited in its ability to coordinate a global response to the COVID-19 outbreak. 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?

Roles of active-site residues in catalysis, substrate binding, cooperativity, and the reaction mechanism of the quinoprotein glycine oxidase [Enzymology]

The quinoprotein glycine oxidase from the marine bacterium Pseudoalteromonas luteoviolacea (PlGoxA) uses a protein-derived cysteine tryptophylquinone (CTQ) cofactor to catalyze conversion of glycine to glyoxylate and ammonia. This homotetrameric enzyme exhibits strong cooperativity toward glycine binding. It is a good model for studying enzyme kinetics and cooperativity, specifically for being able to separate those aspects of protein function through directed mutagenesis. Variant proteins were generated with mutations in four active-site residues, Phe-316, His-583, Tyr-766, and His-767. Structures for glycine-soaked crystals were obtained for each. Different mutations had differential effects on kcat and K0.5 for catalysis, K0.5 for substrate binding, and the Hill coefficients describing the steady-state kinetics or substrate binding. Phe-316 and Tyr-766 variants retained catalytic activity, albeit with altered kinetics and cooperativity. Substitutions of His-583 revealed that it is essential for glycine binding, and the structure of H583C PlGoxA had no active-site glycine present in glycine-soaked crystals. The structure of H767A PlGoxA revealed a previously undetected reaction intermediate, a carbinolamine product-reduced CTQ adduct, and exhibited only negligible activity. The results of these experiments, as well as those with the native enzyme and previous variants, enabled construction of a detailed mechanism for the reductive half-reaction of glycine oxidation. This proposed mechanism includes three discrete reaction intermediates that are covalently bound to CTQ during the reaction, two of which have now been structurally characterized by X-ray crystallography.

Non-traditional security cooperation between China and south-east Asia: implications for Indo-Pacific geopolitics

8 January 2020 , Volume 96, Number 1

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.

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 development

Firstly, 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 manufacturing

Developers, 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 distribution

Global 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.

Nanodomains can persist at physiologic temperature in plasma membrane vesicles and be modulated by altering cell lipids [Research Articles]

The formation and properties of liquid-ordered (Lo) lipid domains (rafts) in the plasma membrane are still poorly understood. This limits our ability to manipulate ordered lipid domain-dependent biological functions. Giant plasma membrane vesicles (GPMVs) undergo large-scale phase separations into coexisting Lo and liquid-disordered lipid domains. However, large-scale phase separation in GPMVs detected by light microscopy is observed only at low temperatures. Comparing Förster resonance energy transfer-detected versus light microscopy-detected domain formation, we found that nanodomains, domains of nanometer size, persist at temperatures up to 20°C higher than large-scale phases, up to physiologic temperature. The persistence of nanodomains at higher temperatures is consistent with previously reported theoretical calculations. To investigate the sensitivity of nanodomains to lipid composition, GPMVs were prepared from mammalian cells in which sterol, phospholipid, or sphingolipid composition in the plasma membrane outer leaflet had been altered by cyclodextrin-catalyzed lipid exchange. Lipid substitutions that stabilize or destabilize ordered domain formation in artificial lipid vesicles had a similar effect on the thermal stability of nanodomains and large-scale phase separation in GPMVs, with nanodomains persisting at higher temperatures than large-scale phases for a wide range of lipid compositions. This indicates that it is likely that plasma membrane nanodomains can form under physiologic conditions more readily than large-scale phase separation. We also conclude that membrane lipid substitutions carried out in intact cells are able to modulate the propensity of plasma membranes to form ordered domains. This implies lipid substitutions can be used to alter biological processes dependent upon ordered domains.
