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.

Rapid finger stick test to detect antibodies against SARS-CoV-2 variants

A new preprint reports a semi-quantitative test that can measure neutralizing antibodies to the SARS-CoV-2 pathogen at the point of care, using a finger stick or venipuncture blood.

Study may pave the way for a more personalized approach to COVID-19 diagnosis and treatment

Using some of the most advanced molecular sequencing tools available to evaluate COVID-19 rapid autopsy tissues, researchers have identified four major regulatory pathways, specific molecular effectors behind COVID-19 symptoms, and differences that drive diverging clinical courses among individual patients.

Emergence of SARS-CoV-2 immune escape variants in an immunocompromised patient

A German case study recently published in the journal Nature Communications has characterized a long-term severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection dynamics in an immunosuppressed kidney transplant recipient and provided evidence for the evolution of SARS-CoV-2 into potentially harmful immune escape mutants during persistent infections.
