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.

B.1.1.7 variant 45% more infectious than wild-type SARS-CoV-2, but can be effectively contained by BNT162b2 vaccine

The SARS-CoV-2 B.1.1.7 variant, also called the UK variant, was identified in London as well as in Southeast and East of England in December 2020. Since its emergence, the UK variant has undergone several mutations that have been said to have altered its infectivity and transmissibility in the community. The B.1.1.7 variant is defined by 17 mutations, several of which are located in the SARS-CoV-2 spike protein that mediates viral attachment and entry into human cells.

Plant-derived compound isorhamnetin may have antiviral potential against SARS-CoV-2

The lack of new or repurposed drugs to treat patients with severe or critical COVID-19 has been one of the biggest hurdles to reducing mortality rates in the ongoing pandemic caused by SARS-CoV-2. A new study describes the potential for the use of the plant molecule isorhamnetin in the management of this virus.
