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.

Structured 'cut-and-paste' design enables streamlined development of SARS-CoV-2 molecular probes

A seminal study by US researchers, currently available on the bioRxiv* preprint server, demonstrates how structure-based design can be efficiently employed to develop molecular probes targeting the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike and its domains, with possible future use in diagnostics, treatment and vaccine development.

Statin therapy linked to lower death rate in hospitalized patients with COVID-19

The use of cholesterol-lowering drugs called statins is associated with a lower death rate and a lower incidence of mechanical ventilation in patients hospitalized with Coronavirus disease 2019 (COVID-19), researchers report June 24 in Cell Metabolism.

Abnormal findings in testicular tissue of COVID-19 patients, SARS-CoV-2 mostly undetected

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused over 9.263 million cases and taken more than 477,000 lives as of June 24, 2020 – just six months after the initial outbreak in Wuhan, China, was reported. The illness, called COVID-19 disease, caused by SARS-CoV-2 is a severe pneumonic illness, caused by the entry of the virus into the type II alveolar cells.

Smoking increases risk of COVID-19 for men but not women

Even as the COVID-19 pandemic continues to spread over the world, scientists have had to come to terms with the fact that they don’t know much about the SARS-CoV-2 or the disease it causes. Now, a new study by researchers at the University College Cork, Ireland, and published on the preprint server medRxiv in June 2020 discusses the differences in COVID-19 risk between men and women who smoke.

Pangolin version of SARS-CoV-2 can cause COVID-19-like illness

The results of a recent multinational research endeavor, currently available on the bioRxiv preprint server, display the biological framework of SARS-CoV-2-related coronavirus in pangolins and reveal striking similarities to coronavirus disease (COVID-19) in humans, but also show that it can be transmitted vertically to the fetus.

Scientists create 'all-atom' model of SARS-CoV-2 spike protein

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes the coronavirus disease (COVID-19), an illness that has spread across the globe, infecting more than 9 million people. The novel coronavirus invades cells through "spike proteins," which sticks and binds itself to a host cell.

Single-dose Israeli vaccine candidate protective against SARS-CoV-2

Now, a new Israeli study published on the preprint server bioRxiv in June 2020 reports a new recombinant vaccine expressing the S or spike protein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to be highly protective with a single dose in an animal model. This could be a gamechanger in the fight to contain the outbreak.

Interesting study on which species may be infected by SARS-CoV-2

The team from the University of Cambridge and the Pirbright Institute found that the Spike protein on SARS-CoV-2 engages with the host cell receptor angiotensin-converting enzyme 2 (ACE2) across a wide range of animals, even though the Spike binding site shows a between-species variation in its amino acid composition.

Promising candidate monoclonal antibodies show "exquisite potency" against SAR-CoV-2

Researchers at Columbia University, Dana-Farber Cancer Institute, and the National Institutes of Health have identified and characterized a range of monoclonal antibodies that potently neutralize severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Direct structural link between SARS-CoV-2 and essential fatty acid

Now, a new study published on the preprint server bioRxiv in June 2020 reports the discovery of a novel free fatty acid (FFA) binding pocket on the SARS-CoV-2 virus that could explain in part the viral effects of hyperinflammation, immune modulation, and membrane structure.

Blood types and COVID-19 risk confirmed

Blood type may play a pivotal role in driving disease severity among coronavirus disease (COVID-19) patients. Genetic analysis of COVID-19 patients has shown that people with blood type O seemed to be protected against severe disease. In contrast, those with blood type A may experience complications tied to the viral infection.

Novel SARS-CoV-2 antibody cocktail impeccably mimics human antibody response

By using both humanized mice and convalescent patients, the researchers from the US and Singapore successfully generated non-competing and highly potent monoclonal antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein that could potentially be combined to form antibody cocktails. Their groundbreaking paper is published in the leading research journal Science.

First genome-wide CRISPR screen reveals genes that control SARS-CoV-2 infection

By performing a genome-wide CRISPR screen on the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), U.S. researchers identified novel proviral genes and pathways, and highlighted host genes that may regulate coronavirus disease (COVID-19) pathogenesis, as well as revealing potential targets for novel treatment approaches. Their findings are currently available on the bioRxiv* preprint server.
