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.

SARS-CoV-2 Omicron variant binding to its receptor and therapeutic entities

Researchers generated a set of computed structural models of the Omicron receptor-binding domain attached to its receptor angiotensin-converting enzyme.

Omicron evades immunity more than other SARS-CoV-2 variants

Researchers find that the SARS-CoV-2 Omicron variant shows a much more extensive escape from vaccine-elicited immunity.

Machine learning method for determining impact of mutations in the SARS-CoV-2 RBD on binding and antibody escape

Deep mutational learning (DML) is a technique developed by researchers from multiple institutions that combines experimental yeast display screening of RBD mutagenesis libraries with deep sequencing and machine learning.

Iota-carrageenan inhibits replication of SARS-CoV-2 VOCs

Scientists have recently reported the efficacy of carrageenan against both the SARS-CoV-2 original strain as well as the Alpha, Beta, Gamma, and Delta VOCs.

Glycans strengthen interaction between viral spike proteins and ACE2 receptors on host cells

A new study shows that the ACE2 and RBD of coronavirus spike fragments have different binding strengths and dissociation rates when they are glycosylated and non-glycosylated.

Impact of tumor environments on susceptibility and course of disease in those infected with SARS-CoV-2

A review assessed the impact of "hot" vs. "cold" immune/tumor environments (and associated therapies) on susceptibility and disease course in subjects with these two types of tumors and infected with SARS-CoV-2 to decipher the mechanisms that drive these adverse outcomes in COVID-19 infected cancer patients.

New tool to help map immune escape with SARS-CoV-2 mutations

A new study discusses a computational program that can be used to substitute for actual experimental evidence of the biologic impact of new mutations.

12 Dec 2021

Study finds mutational changes in Omicron variant likely increase transmissibility

A new study presented evidence for a large number of mutational changes in the Omicron variant which will likely increase its transmissibility and significantly decrease the neutralization capacity of monoclonal antibodies, leading to a decline in vaccine efficacy.
