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.

The Future of EU–US Cooperation in Space Traffic Management and Space Situational Awareness

29 August 2019

As more space activities develop, there is an increasing requirement for comprehensive space situational awareness (SSA). This paper provides an overview of the current landscape in SSA and space traffic management as well as possible scenarios for EU–US cooperation in this area.

Summary

  • Space situational awareness (SSA) and space traffic management (STM) are essential for sustainable near-Earth orbit. International cooperation in SSA and STM is vital with the growing number of satellite operators and the increasingly complex space environment.
  • The various definitions of SSA and STM are ambiguous. Understanding the activities that fall under each term can better assist in finding areas for cooperation and collaboration.
  • SSA has historically been a military activity, leading to an incomplete public catalogue of its use and barriers to sharing information with other states and the commercial sector. The rise in private space actors has increased the number of commercial STM providers and, with plans in the US to move responsibility for STM to civilian control, there will likely be more opportunities for international collaboration, particularly through the EU Space Surveillance and Tracking (SST) programme.
  • Individual EU member states possess developed STM capabilities, but overall these are still some way behind those of allies such as the US. Further investment in STM infrastructure and programmes is required for the EU and individual European states to be an essential partner to the US and add value to the global effort.
  • There are worldwide challenges, both political and technical, to providing STM coverage, which may lead to a lack of collaboration and gaps in understanding of activities in orbit. Existing sensors have limitations in terms of the size of objects that can be detected and the precision with which their movements can be predicted. These capability gaps represent opportunities for the EU to contribute.
  • The EU can build on its tradition of support for openness and civil society by creating a system that fosters an environment of cooperation and collaboration involving industry, commercial STM providers and the wider international community.
  • Although collaboration in STM is vital, the EU should also aim to tackle issues within the wider definition of SSA including space weather, intelligence and the security of ground stations.
  • The EU is well placed to become a global leader in SSA and STM. However, it needs to take into consideration the current political and technical landscape when making decisions regarding investment in capabilities and the pursuit of international partnerships.

EU–US Cooperation on Tackling Disinformation

3 October 2019

Disinformation, as the latest iteration of propaganda suitable for a digitally interconnected world, shows no signs of abating. This paper provides a holistic overview of the current state of play and outlines how EU and US cooperation can mitigate disinformation in the future.

  • EU and US cooperation on tackling disinformation needs to be grounded in an international human rights framework in order to bridge the differences of both parties and include other countries facing this challenge.
  • The disinformation debate needs to be reformulated to cover systemic issues rather than merely technical or security concerns. A lag in regulatory development has led to systemic vulnerabilities. In this context, policymakers need to push for more evidence-based analysis, which is only attainable if technology companies engage in honest debate and allow meaningful access to data – as determined by government appointed researchers rather than the companies themselves – taking into account and respecting users’ privacy.
  • Data governance needs to be the focus of attempts to tackle disinformation. Data’s implications for information, market and power asymmetries, feed into and exacerbate the problem.
  • Policymakers should focus on regulating the distribution of online content rather than the subject matter itself, which may have implications for freedom of speech.
  • Disinformation is mainly the result of inefficient gatekeeping of highly extractive digital companies. The old gatekeepers, journalists and their respective regulators, need to be actively engaged in devising the new regulatory framework.
  • Legacy media need to urgently consider the issue of ‘strategic silence’ and avoid being co-opted by political actors aiming to manipulate the accelerated, reactive news cycle by engaging in divisive ‘clickbait’ rhetoric verging on disinformation and propaganda. When strategic silence is not an option, contextual analysis is fundamental.
  •  The EU delegation should assist the coordination of EU–US efforts to tackle disinformation by drawing on the work and expertise at the G7 Rapid Response Mechanism (RRM), the Transatlantic Commission on Election Integrity (TCEI), the European Centre of Excellence for Countering Hybrid Threats (Hybrid CoE), the High-level Panel on Digital Cooperation, and work with the International Telecommunication Union (ITU) to foster a long-term interdisciplinary forum to harness technological innovation to protect and support democracy from threats such as disinformation.
  • The EU and US must avoid rushed regulation that may condone enhanced surveillance or vilify journalism that scrutinizes those in power in the name of security.

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.

Can fluorescence-guided surgery help identify all lesions in unknown locations or is the integrated use of a roadmap created by preoperative imaging mandatory? A blinded study in prostate cancer patients.

Rationale: Lymphatic tracers can help visualize the lymphatic drainage patterns and sentinel nodes of individual prostate cancer patients. To determine the role of nuclear medicine, in particular the positional guidance of a SPECT/CT-based 3D imaging roadmap, in this process we studied to which extend fluorescence-guidance underestimated the number of target lesions. Methods: SPECT/CT imaging was performed after intraprostatic tracer administration of either ICG-99mTc-nanocolloid (hybrid tracer group) or 99mTc-nanocolloid to create a roadmap that depicted all sentinel nodes (SNs). Patients who received 99mTc-nanocolloid were injected with "free" ICG immediately prior to surgery ("free" ICG group). Before unblinding, fluorescence-guidance was used for intraoperative SN identification. This was followed by extended pelvic lymph node dissection (ePLND). Following unblinding of the SPECT/CT images, the number of missed SN’s were recorded and their resection was pursued when the anatomy allowed. Results: Preoperative SPECT/CT revealed no differences in the SN identification rate between ICG-99mTc-nanocolloid and 99mTc-nanocolloid. However, fluorescence-guidance only allowed intraoperative removal of all SNs in 40% of patients in the hybrid tracer group and in 20% of patients in the "free" ICG group. Overall, 75.9% of the intraoperatively resected SNs in the hybrid tracer group and 51.8% of the SNs in the "free" ICG group were removed solely under fluorescence-guidance. During ePLND 22 additional SNs were resected (7 in the hybrid tracer group and 15 in the "free" ICG group). After unblinding 18 remaining SNs were identified (6 in the hybrid group and 12 in the "free" ICG group). In the "free" ICG group, ex vivo evaluation of the excised specimens revealed that 14 SNs removed under ePLND or after unblinding contained radioactivity but no fluorescence. Conclusion: The preoperative imaging roadmap provided by SPECT/CT enhanced the detection of prostate SNs in more ectopic locations in 17 of the 25 patients and the hybrid tracer ICG-99mTc-nanocolloid was shown to outperform "free" ICG. Overall, fluorescence-guided pelvic nodal surgery underestimated the number of SNs in 60-80% of patients.

Label-free Visualization of Early Cancer Hepatic Micrometastasis and Intraoperative Image-guided Surgery by Photoacoustic Imaging

Objectives: The detection of cancer micrometastasis for early diagnosis and treatment poses a great challenge for conventional imaging techniques. The aim of study is to evaluate the performance of photoacoustic imaging (PAI) in detecting hepatic micrometastases from melanoma in a very early stage and perform tumor resection by intraoperative photoacoustic image-guidance. Methods: In vivo studies were performed by following protocols approved by the Ethical Committee for Animal Research at Xiamen University. First, a B16 melanoma hepatic metastasis mouse model (n = 10) was established to study the development of micrometastases in vivo. Next, the hepatic metastasis mice models were imaged by scalable PAI instrument, ultrasound, 9.4 T high-resolution magnetic resonance imaging (MRI), positron emission tomography/computed tomography (PET/CT), and bioluminescence imaging. Photoacoustic images acquired with optical wavelengths spanning from 680 to 850 nm were spectrally unmixed by using a linear least-squares method to differentiate various components. Differences in the signal-to-background ratios among different modalities were determined with the two-tailed paired t test. The diagnosis results were assessed with histologic examinations. Excised liver samples from patients diagnosed with hepatic cancer were also examined to identify tumor boundary. In vivo metastatic melanoma removal in surgery was precisely guided by the portable PAI system. Results: PAI achieved as small as ~400 µm hepatic melanoma detection at a depth up to 7 mm in vivo, which could early detect small melanoma compared with ultrasound and MRI in mouse models. The signal ratio of tumor-to-liver acquired with PAI in micrometastases at 8 days (4.2 ± 0.2, n = 6) and 14 days (9.2 ± 0.4, n = 5) were significantly higher than those obtained with PET/CT (1.8 ± 0.1, n = 5 and 4.5 ± 0.2, n = 5, P <0.001 for both). Functional PAI provided dynamic oxygen saturation changes during tumor growth. The limit of detection was measured to be approximately 219 cells per microliter in vitro. We successfully performed intraoperative photoacoustic image-guided surgery in vivo using the rapid portable PAI system. Conclusion: Our findings offer a rapid and effective tool to noninvasively detect micrometastases and guide intraoperative resection as a complementary clinical imaging application.

Intraoperative 68Gallium-PSMA Cerenkov Luminescence Imaging for surgical margins in radical prostatectomy - a feasibility study

Objective: To assess the feasibility and accuracy of Cerenkov Luminescence Imaging (CLI) for assessment of surgical margins intraoperatively during radical prostatectomy (RPE). Methods: A single centre feasibility study included 10 patients with high-risk primary prostate cancer (PC). 68Ga-PSMA PET/CT scans were performed followed by RPE and intraoperative CLI of the excised prostate. In addition to imaging the intact prostate, in the first two patients the prostate gland was incised and imaged with CLI to visualise the primary tumour. We compared the tumour margin status on CLI to postoperative histopathology. Measured CLI intensities were determined as tumour to background ratio (TBR). Results: Tumour cells were successfully detected on the incised prostate CLI images as confirmed by histopathology. 3 of 10 men had histopathological positive surgical margins (PSMs), and 2 of 3 PSMs were accurately detected on CLI. Overall, 25 (72%) out of 35 regions of interest (ROIs) proved to visualize a tumour signal according to standard histopathology. The median tumour radiance in these areas was 11301 photons/s/cm2/sr (range 3328 - 25428 photons/s/cm2/sr) and median TBR was 4.2 (range 2.1 – 11.6). False positive signals were seen mainly at the prostate base with PC cells overlaid by benign tissue. PSMA-immunohistochemistry (PSMA-IHC) revealed strong PSMA staining of benign gland tissue, which impacts measured activities. Conclusion: This feasibility showed that 68Ga-PSMA CLI is a new intraoperative imaging technique capable of imaging the entire specimen’s surface to detect PC tissue at the resection margin. Further optimisation of the CLI protocol, or the use of lower-energetic imaging tracers such as 18F-PSMA, are required to reduce false positives. A larger study will be performed to assess diagnostic performance.

Mobilizing Multinational Military Operations in Africa: Quick Fixes or Sustainable Solutions?

Peacekeeping missions which have sought to address evolving forms of conflict and instability on the African continent – led by the United Nations, African Union and European Union – have frequently been overstretched.

Across regions including the Sahel, the Horn and West Africa, the issues of violent extremism and criminality – often set against a backdrop of collapsing or severely weakened central states – have led to the mobilisation of a diverse set of new collective responses.

These include notable African-led efforts such as AMISOM in Somalia or more recently the G5 Sahel, where France have played a pivotal role in initiating new and more ad hoc approaches to coalition-building.

As existing multinational missions in Africa continue to evolve on the ground and while new collective opportunities increasingly present themselves, it is critical for policymakers to understand how far such efforts reflect meaningful long-term solutions to the challenges of conflict and insecurity.

At this roundtable event, participants will reflect on how such missions become mobilised and legitimised, the extent to which they can be defined as ‘new’, and whether they represent a truly sustainable means to tackle the issue of conflict in Africa.

This roundtable is held in partnership with Cardiff University and the University of Portsmouth and is supported by the Leverhulme Trust.

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.

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.
