Discovery may lead to new treatment approach for people with alcohol-associated liver disease

Investigators at Cedars-Sinai have uncovered a new pathway that helps explain how consuming too much alcohol causes damage to the liver, specifically mitochondrial dysfunction in alcohol-associated liver disease.

Study shows IgA antibodies play a significant role in neutralizing SARS-CoV-2

A recent paper by researchers from Australia, currently available on the medRxiv* preprint server, shows how Immunoglobulin A (IgA) antibodies in individuals who were infected with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) contribute to the neutralization of the virus and its variants, even though this response is heterogeneous and less potent when compared to IgG antibodies.

Investigating taraxerol as a protease inhibitor against SARS-CoV-2

In a recent study posted to the Research Square preprint* server, a team of researchers investigated the toxicity and absorption, distribution, metabolism, and excretion (ADME) characteristics of a potent herbal drug, taraxerol, in the management of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The paper is under consideration for publication in the Structural Chemistry journal.

Booster vaccines found to augment T-cell responses to SARS-CoV-2 Omicron

In a recent study published in the latest issue of the journal Cell, a team of researchers evaluated T-cell reactivity to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant's spike (S) and non-spike proteins.

6 Feb 2022

A novel approach to predict mutations within the SARS-CoV-2 spike

A study posted recently to the bioRxiv* preprint server demonstrated that the emergence of new spike variants of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) can be predicted.
