SARS-CoV-2 mutations strengthen RBD-ACE2 binding, making the virus more infectious

In January 2020, the first complete severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) genome sequence was deposited to GenBank. Since then, the amount of new genome sequences has increased rapidly at GenBank and GISAID. This has laid the foundations for analyzing the virulence, antigenicity, pathogenicity, and transmissibility of SARS-CoV-2 mutations.

SARS-CoV-2 B.1.1.7 and B.1.351 variants exhibit enhanced affinity towards the ACE2 receptor

In a short correspondence paper recently uploaded to the Lancet by Ramanathan, Muthukumar et al. (May 19th, 2021) the affinity of labeled SARS-CoV-2 spike receptor-binding domain proteins sourced from each of these two variants of concern towards human angiotensin-converting enzyme 2 (ACE2) recombinant proteins is investigated using microscale thermophoresis, confirming the enhanced affinity towards the receptor observed in other studies.

FDA approves Rybrevant for treating subset of non-small cell lung cancer

Today, the U.S. Food and Drug Administration approved Rybrevant (amivantamab-vmjw) as the first treatment for adult patients with non-small cell lung cancer whose tumors have specific types of genetic mutations: epidermal growth factor receptor (EGFR) exon 20 insertion mutations.

Study could lead to new antibiotics to fight bacterial infections

One member of a large protein family that is known to stop the spread of bacterial infections by prompting infected human cells to self-destruct appears to kill the infectious bacteria instead, a new study led by UT Southwestern scientists shows.

University of Freiburg professor honored for groundbreaking results on the brain’s immune system

The blood-brain barrier is an impenetrable barrier between the circulating blood and the brain established before birth that prevents immune cells from entering the brain from the body's immune system. Thus, the brain has its own immune system with a key actor called microglia.

Novel broad-spectrum antiviral compounds effective against Zika and SARS-CoV-2

A research team at the University of Alberta, Canada, led by Dr. Daniel Limonta, has described two novel molecules with broad antiviral properties that are effective against a range of virus types, including SARS-CoV-2.

How do common mutations in SARS-CoV-2’s spike affect its binding affinity with host cell receptors?

Antibodies produced during a previous case of COVID-19 or vaccine-induced immunity are targeted towards S protein, where the neutralizing antibodies attach to the Spike RBD domain. Some of the variants have mutations in their RBD domain, causing resistance to the neutralizing antibodies. However, the effect of these mutations on the affinity and kinetics of the binding of Spike RBD to ACE2 is not clear. A new study has been published on the bioRxiv* preprint server, which deals with the study of affinity and kinetic analysis of the interface between Spike RBD and ACE2 at physiological temperatures.

Pfizer-BioNTech vaccination not associated with platelet activation in new study

Among the devastating complications of severe or critical coronavirus disease 2019 (COVID-19), clot formation ranks high in the adverse impact it creates. An important question is whether SARS-CoV-2-spike-based vaccines also cause such coagulopathies. A new study, released as a preprint on the medRxiv* server, examines this risk for the first time.

Scientists discover novel defensive response to SARS-CoV-2

Scientists from Hokkaido University have discovered a novel defensive response to SARS-CoV-2 that involves the viral pattern recognition receptor RIG-I. Upregulating expression of this protein could strengthen the immune response in COPD patients.

Facets of SARS-CoV-2 infection and animal models

A new study in the journal Frontiers in Cell and Developmental Biology discusses the ribonucleic acid (RNA) genome of the virus, and the mechanisms by which it establishes infection within the host cell. The researchers also summarize the development of animal models of COVID-19, which will both help understand the clinical features of the illness, and indicate new approaches for the treatment of the infection.

Metal complexes against coronavirus

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused more than 3.42 million deaths worldwide. Despite the fact that there are vaccines for SARS-CoV-2, the emergence of new variants and the lack of adequate treatments have encouraged the search for new ways to combat this disease more effectively.
