A plea for equitable global access to COVID‐19 diagnostics, vaccination and therapy: The NeuroCOVID‐19 Task Force of the European Academy of Neurology

Coronavirus disease 2019 (COVID‐19), a multi‐organ disease caused by severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), continues to challenge health and care systems around the globe. The pandemic has disrupted acute neurology services and routine patient care and has impacted the clinical course in patients with chronic neurological disease. COVID‐19 appears to have exposed inequalities of societies and healthcare systems and had a disproportionate impact on already vulnerable communities. The next challenge will be to set up initiatives to stop disparities in all aspects related to COVID‐19. From the medical perspective, there is a need to consider inequalities in prevention, treatment and long‐term consequences. Some of the issues of direct relevance to neurologists are summarised. With this appraisal, the European Academy of Neurology NeuroCOVID‐19 Task Force intends to raise awareness of the potential impact of COVID‐19 on inequalities in healthcare and calls for action to prevent disparity at individual, national and supranational levels

Mice Deficient in Nuclear Factor of Activated T-Cell Transcription Factor c2 Mount Increased Th2 Responses after Infection with Nippostrongylus brasiliensis and Decreased Th1 Responses after Mycobacterial Infection

Infection of nuclear factor of activated T-cell transcription factor c2 (NFATc2)-deficient mice with the helminth Nippostrongylus brasiliensis led to a distinct increase in interleukin-4 (IL-4) and IL-5 protein synthesis by lymph node and spleen cells and to elevated serum immunoglobulin E (IgE) levels in comparison to those seen with infected control mice. While IL-4, IL-5, and IL-13 mRNA expression was also enhanced in lymph node cells from the lungs of infected NFATc2(−/−) mice, the number of T cells secreting Th2-type lymphokines remained the same in mice infected with N. brasiliensis. In contrast, lymphocytes from NFATc2-deficient mice infected with Mycobacterium bovis BCG secreted less gamma interferon than lymphocytes from infected control mice. These findings indicate that NFATc2 is an activator of Th1 responses and a suppressor of Th2 responses in vivo
