T cell epitopes from recovered COVID-19 patients identified for vaccine

A new study by researchers at The Hong Kong University of Science and Technology and published on the preprint server bioRxiv in August 2020 collates the available database of SARS-CoV-2 T cell epitopes gathered from 8 studies of COVID-19 patients who recovered. This could serve as a launchpad to fill in knowledge gaps regarding the immunological aspects of this disease, and drive towards an effective T cell vaccine.

Rabbits susceptible to SARS-CoV-2: Red flag for potential virus reservoir

A new study by scientists in the Netherlands and published on the preprint server bioRxiv* in August 2020 shows that the severe acute respiratory coronavirus-2 (SARS-CoV-2) can infect rabbits, which opens the door for possible circulation in rabbit farms and another potential source of animal to human SARS-CoV-2 infection. This finding calls for urgent research on the prevalence of the virus in farmed rabbits.

Using SARS-CoV-2 epitope to construct a vaccine

A new study published on the preprint server bioRxiv* in August 2020 reports the use of prediction and advanced simulation techniques to identify a novel T cell epitope on the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that could serve as the basis for a customized vaccine with broad-based efficacy.

SARS-CoV-2 Neucleocapside (N) protein is heavily glycosylated

However, the nucleocapsid (N) protein is also extremely abundant and, therefore, a useful target for both vaccine and diagnostic test development. A new study published on the preprint server bioRxiv in August 2020 reveals the structure of this protein, a valuable step in using it for these purposes.

Researchers develop advanced imaging technique to visualize effects of valencies on B cell responses

Designing a vaccine starts with finding the right ingredients. Every infectious agent has molecules, called antigens, that the immune system could potentially recognize and attack. So scientists must carefully consider which antigens should go into a vaccine.
