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.

Human to animal transmission of SARS-CoV-2 in households is common

Coronaviruses are seen in multiple mammalian species. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of the COVID-19 pandemic, is said to have passed to humans from a mammalian source and to have originated from an animal reservoir as a zoonotic pathogen.

SARS-CoV-2 recruits heme metabolites in antibody evasion

A research paper recently published in the journal Science Advances by Cherepanov et al. (April 22nd, 2021) demonstrated that the NTD binds to biliverdin, a product of heme catabolism, leading to enhanced antibody escape at physiologically relevant concentrations.

Researchers suggest new approach to build a 'nanopore' biosensor for detecting specific molecules

Researchers have spent more than three decades developing and studying miniature biosensors that can identify single molecules. In five to 10 years, when such devices may become a staple in doctors' offices, they could detect molecular markers for cancer and other diseases and assess the effectiveness of drug treatment to fight those illnesses.

Why do we lose our sense smell/taste with COVID?

The angiotensin-converting enzyme 2 (ACE2) enzyme attached to the membranes of cells is the entry point for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). They are abundantly found all over the body and most prominently in the lungs and nose.

Nucleocapsid-based vaccines may prevent SARS-CoV-2 dissemination to distal organs

A team of scientists recently investigated and compared the efficacy of spike-based and nucleocapsid-based COVID-19 vaccines in mice infected with SARS-CoV-2. Their findings reveal that nucleocapsid-based vaccines are effective in preventing SARS-CoV-2 infection in distal organs, such as the brain.

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.
