Vaccines, Antibodies and Drug Libraries. The Possible COVID-19 Treatments Researchers Are Excited About
In early April, about four months after a new, highly infectious coronavirus was first identified in China, an international group of scientists reported encouraging results from a study of an experimental drug for treating the viral disease known as COVID-19. It was a small study, reported in the New England Journal of Medicine, but showed that remdesivir, an unapproved drug that was originally developed to fight Ebola, helped 68% of patients with severe breathing problems due to COVID-19 to improve; 60% of those who relied on a ventilator to breathe and took the drug were able to wean themselves off the machines after 18...

All Your Coronavirus Questions, Answered
One of the worst symptoms of any plague is uncertainty—who it will strike, when it will end, why it began. Merely understanding a pandemic does not stop it, but an informed public can help curb its impact and slow its spread. It can also provide a certain ease of mind in a decidedly uneasy time. Here are some of the most frequently asked questions about the COVID-19 pandemic from TIME’s readers, along with the best and most current answers science can provide. A note about our sourcing: While there are many, many studies underway investigating COVID-19 and SARS-CoV-19, the novel coronavirus that causes the illn...

An Animal Model of Acute and Chronic Chagas Disease With the Reticulotropic Y Strain of Trypanosoma cruzi That Depicts the Multifunctionality and Dysfunctionality of T Cells
In conclusion, during acute T. cruzi infection with the reticulotropic Y strain, immune activation leads to the generation of antigen-specific multifunctional CD4+ Th1 and CD8+ Tc1 cells and their regulation by inhibitory receptor co-expression. In contrast, during chronic T. cruzi infection, the chronicity of the infection induces a moderate inflammatory infiltrate in colon and liver tissues accompanied with poor T cell effector function that is possibly related to the co-expression of inhibitory receptors on T cells, but this phenomenon does not occur in cytotoxic CD8+ T cells. Taken together, these data supp...
