Alteration in gut microbiome may lead to hyperinflammation in severe COVID-19

A team of international scientists has recently identified a distinct set of proinflammatory mediators and metabolites associated with the fatal consequences of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Moreover, they have established a link between gut microbiome alteration and hyper-inflammatory response in patients with severe COVID-19. The study is currently available on the bioRxiv* preprint server.

New approach could be a useful tool in the fight against cancer drug resistance

Using a virus to purposely mutate genes that produce cancer-driving proteins could shed light on the resistance that inevitably develops to cancer drugs that target them, a new study led by UT Southwestern scientists suggests.

Viral phosphoesterases (including in CoVs) can restrict antiviral innate immunity

An interesting new study describes the activities of a family of viral enzymes called two-histidine-phosphoesterases (2H-PEs), found in coronaviruses (CoVs) and rotaviruses, as well as a mammalian A-kinase anchoring protein enzyme, AKAP7, that shares the same function. Together called 2’,5’-PEs, these enzymes all break down 2’,5’-oligoadenylate compounds that activate the antiviral enzyme ribonuclease L (RNase L).

Zinc inhibits SARS-CoV-2’s main protease in vitro

Zinc has antiviral properties. However, the detailed kinetics and the mechanism of zinc in the inhibition of viruses, particularly SARS-CoV-2 – the causative virus of COVID-19 – is unclear. To probe the role of zinc as an anti-SARS-CoV-2 agent at the structural and molecular level, researchers in India studied the binding kinetics and the inhibition mechanism of zinc with SARS-CoV-2’s viral proteins.
