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.

Natural selection and adaptation of SARS-CoV-2 in mammals

Researchers of the Hubei University of Medicine, China, have analyzed several mutations in different variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from mammal species that suggest natural selection and host adaptation are occurring in the virus.

Research explores sex differences in placental defenses against SARS-CoV-2 infection

A plethora of earlier studies has reported on the differences between the sexes in susceptibility to the currently circulating severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), as well as its severity. A new preprint research paper posted to the bioRxiv* server extends this to the placenta in pregnancy.

New nanoparticle SARS-CoV-2 vaccine confers robust protection with single dose after two weeks

In a methodologically ‘state-of-the-art’ approach, US researchers have developed a protein-based nanoparticle vaccine against coronavirus disease (COVID-19), with a swift generation of antibodies and the potential to protect individuals who cannot receive other COVID-19 vaccines for medical reasons. The research is posted to the bioRxiv* preprint server.
