Angiotensin News and Research

RSS

Angiotensin is an oligopeptide in the blood that causes vasoconstriction, increased blood pressure, and release of aldosterone from the adrenal cortex. It is a powerful dipsogen. It is derived from the precursor molecule angiotensinogen, a serum globulin produced in the liver. It plays an important role in the renin-angiotensin system.

Research suggests toll-like receptor 4 appears to play role in severe COVID

A group of researchers re-evaluated their previously proposed hypothesis, which stated that the TLR4 activated by the spike glycoprotein S1 domain increases ACE2 expression and, thereby, aids in COVID-19 infection.

VPS29 gene facilitates coronavirus cell entry

In a research paper recently uploaded to the bioRxiv* preprint server by Poston et al. (August 8th, 2021), common host factors amongst several zoonotic pathogens are explored by CRISPR-Cas9 screening in human lung cells, focusing in particular on the betacoronavirus genus.

Study shows impaired SARS-CoV-2 mRNA vaccine antibody response in individuals with chronic conditions

A recent study in Colorado used real-world data to evaluate if individuals with chronic conditions have reduced antibody response to COVID-19 mRNA vaccines. The study investigated whether some medical conditions may impact antibody response to the mRNA vaccines.

Research shows how SARS-CoV-2 variants are evolving towards increased furin cleavage efficiency

The spike protein comprises of two subunits: S1 subunit having the receptor-binding domain (RBD) that helps it to bind to the angiotensin-converting enzyme 2 (ACE2), which is present on the cell surface of the host, and the S2 subunit that helps in the fusion of the cellular membrane and the viral membrane.

Scientists identify calpeptin as potential inhibitor of SARS-CoV-2

A team of US-based scientists has recently conducted a robust high-throughput screening to identify potential entry inhibitors of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The screening identifies calpeptin as a potent and highly specific inhibitor of SARS-CoV-2 and its variants. The study is currently available on the bioRxiv* preprint server.

Cetylpyridinium chloride-containing mouthwashes shown to inhibit SARS-CoV-2 in oral cavity

A team of international scientists has recently demonstrated the usefulness of cetylpyridinium chloride-containing mouthwashes in inhibiting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and reducing the risk of viral transmission. The study is currently available on the bioRxiv* preprint server.

9 Aug 2021

New insight into impact of SARS-CoV-2 mutations on receptor binding

A recent study by Canadian researchers, currently available on the bioRxiv* preprint server, contributes to the growing body of literature on emerging variants of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by appraising the impact of single mutations on their overall antigenicity and binding affinity for the angiotensin-converting enzyme 2 (ACE2) receptor.

9 Aug 2021

Virus-like particles reveal unexpected mechanism for increased fitness and spread of SARS-CoV-2

Researchers in the United States have developed a new model for testing mutations in the four structural proteins of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

9 Aug 2021

Affinity maturation of SARS-CoV-2 antibodies make them more powerful and resistant to escape mutations

A new study in the journal Immunity shows in fascinating detail how antibodies elicited by this virus show affinity maturation, a process occurring by somatic hypermutation (SHM) in the lymphoid germinal centers, to become more specific in their recognition of antigens.
