Researchers around the world are a step closer to a better understanding of the intricacies of COVID-19 thanks to two new web resources developed by investigators at Baylor College of Medicine and the University of California San Diego. The resources are freely available through the Signaling Pathways Project (Baylor) and the Network Data Exchange (UCSD).

Researchers uncover early results about an existing tuberculosis vaccine that has been hypothesized to help against the coronavirus
While scientists race to develop and test a vaccine effective against SARS-CoV-2, the virus that causes COVID-19, recent studies have indicated that countries with widespread BCG vaccination appear to be weathering the pandemic better than their counterparts. This has led many researchers to suspect that BCG vaccine, which immunizes against tuberculosis, might offer protection against COVID-19.

T cells take the lead in controlling SARS-CoV-2 and reducing COVID-19 disease severity
Ever since SARS-CoV-2 first appeared, researchers have been trying to understand whether sometimes the immune system does more harm than good during the acute phase of COVID-19. The latest study by researchers at La Jolla Institute for Immunology clearly argues in favor of the immune system.

Designed antiviral proteins inhibit SARS-CoV-2 in the lab
Computer-designed small proteins have now been shown to protect lab-grown human cells from SARS-CoV-2, the coronavirus that causes COVID-19.
In the experiments, the lead antiviral candidate, named LCB1, rivaled the best-known SARS-CoV-2 neutralizing antibodies in its protective actions. LCB1 is currently being evaluated in rodents.
COVID-19 is caused by a virus known as SARS-CoV-2, which is similar in structure to two other viruses that have caused recent outbreaks: SARS-CoV, which caused an outbreak of SARS in 2003, and MERS-CoV, the cause of a 2012 outbreak of Middle East Respiratory Syndrome.

Tiny antibody component highly effective against SARS-COV-2 in animal studies
University of Pittsburgh School of Medicine scientists have isolated the smallest biological molecule to date that completely and specifically neutralizes the SARS-CoV-2 virus, which is the cause of COVID-19. This antibody component, which is 10 times smaller than a full-sized antibody, has been used to construct a drug - known as Ab8 - for potential use as a therapeutic and prophylactic against SARS-CoV-2.

Which immune response could cause a vaccine against COVID-19?
Immune reactions caused by vaccination can help protect the organism, or sometimes may aggravate the condition. It is especially important now when multiple vaccines against COVID-19 are being developed. The top immunologists analyse types of immune response to predict what kind of vaccine would be the best.
