How antibodies neutralize SARS-CoV-2 in convalescent patients

A new study by researchers from the United Kingdom and Taiwan and published on the preprint server bioRxiv in June 2020 describes the structural basis for the neutralizing effect of the SARS-CoV-2 antibody on the virus. This also indicates a possible therapeutic molecule by identifying its binding epitope as possibly a major neutralizing site.

Study reveals novel mechanism that triggers a cell-mediated immune response

Viruses and other disease-causing microbes influence the type of immune response their hosts will develop against them. In some cases, the predominant response involves antibodies, proteins made by the immune system that specifically recognize parts of the invading microbe and mediate its destruction.

Protein design can solve the puzzle of Parkinson's disease

Dopamine is a neurotransmitter involved in everything from higher cognitive functions to motor control, motivation, arousal, reinforcement, and sexual gratification, the receptors it acts on have been a longstanding target for treating disorders like Parkinson's disease, which is caused by the degeneration of dopamine-using neurons that control movement.

SARS-CoV-2 can adversely affect cardiac cells and heart function

A research group from Germany demonstrated a direct toxic effect of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on cardiac cells in their paper published on the bioRxiv* preprint server. The finding warrants an in-depth analysis of cardiac tissue in certain coronavirus disease (COVID-19) patients, as well as close monitoring for any direct cardiomyocyte injury.

Study reveals how essential SARS-CoV-2 protein can be stabilized and scaled for production

A research group from the University of Texas in Austin described a high-yield production of a stabilized severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein (S-protein) that may accelerate the development of vaccines and diagnostic tests. This methodological 'tour de force' paper is currently available on the bioRxiv* preprint server.

X-ray experiments demonstrate a new way to block the entry of SARS-CoV-2

As scientists across the globe race to develop a vaccine against SARS-CoV-2, the coronavirus that causes COVID-19, an international team led by Davide Corti at Vir Biotechnology and David Veesler at the University of Washington has been working around the clock on a complementary approach - identifying neutralizing antibodies that could be used as a preventative treatment or as a post-exposure therapy.

Novel insights on SARS-CoV-2 cell entry may inform further vaccine and treatment development

A research group from Harvard Medical School reported two cryo-electron microscopy structures derived from a single preparation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike (S) protein in their paper available on the preprint server bioRxiv. Understanding the nuances of prefusion and postfusion conformations shed light on viral cell entry and may, in turn, guide the development of vaccines and drugs.
