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.

Study pinpoints genes responsible for kidney function

Recently scientists pinpointed 182 genes likely responsible for kidney function—most of which can be targeted with existing drugs.

SARS-Cov-2 spike proteins can directly impact the function of blood-brain barrier

Like a key, SARS-CoV-2 - the virus that causes coronavirus disease 2019 (COVID-19) - attaches to specific molecules on the host cell surface, opening gateways into the cell interior.

Scientists use molecular dynamics simulations to reveal the secrets of SARS-CoV-2 virus

The virus wreaking havoc on our lives is an efficient infection machine. Comprised of only 29 proteins (compared to our 400,000), with a genome 1/200,000 the size of ours, SARS-CoV-2 is expertly evolved to trick our cells to contribute its machinery to assist in its propagation.

Nanoparticle SARS-CoV-2 tool could accelerate the search for drugs

A team of scientists from the National Center for Advancing Translational Sciences and Naval Research Laboratory in Washington, D.C., has developed a new tool that mimics how SARS-CoV-2 -- the virus that causes COVID-19 -- infects a cell, information that could potentially speed the search for treatments against the disease.

First lethal mouse model established for COVID-19 infection

Army scientists have developed the first lethal mouse model of SARS-CoV-2, the virus that causes COVID-19, using mice that were genetically engineered to express the human ACE2 gene--a key mechanism by which the virus enters human cells.

Study shows coronavirus does not induce cross-protective immune antibodies

According to researchers, patients infected with severe acute respiratory syndrome coronavirus (SARS-CoV) or SARS-CoV-2 generate antibodies that adhere to the other coronavirus; however, the cross-reactive antibodies are not actually cross-protective, as far as cell-culture experiments are concerned.
