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.

Potent pan-β-CoV human monoclonal antibody has in vivo activity in multiple animal models

Researchers evaluated the efficacy of viral spike domain 2-specific human monoclonal antibodies delivered intranasally, against all beta coronaviruses in hamsters and mice.

Natural SARS-CoV-2 infection-induced anti-spike antibody responses

Researchers demonstrated the anti-spike antibody response to SARS-CoV-2 infection and further estimated the acute SARS-CoV-2 infection-induced Ab activity against recently emerged variants like Omicron.

10 Mar 2022

Cross-species infectivity of SARS-CoV-2 variants correlated with prevalence

New research discusses the role of mutations in the receptor-binding domain of the spike protein in the generation of antibody resistance and loss of vaccine efficacy.

10 Mar 2022

Study finds chimeric mRNA induces potent and broadly acting neutralizing antibodies against SARS-CoV-2 variants

Researchers explored strategies to develop an mRNA-based COVID-19 vaccine that could elicit safer and wider protection against SARS-CoV-2 variants of concern.

10 Mar 2022

Engineered SARS-CoV-2 immunogens elicit broadly neutralizing antibodies

New research describes a novel approach whereby SARS-2 antigens were analyzed for conserved sites that may be targeted by broadly neutralizing antibodies that will confer immunity to other Sarbecoviruses.

10 Mar 2022

Study isolated largest panel of β-CoV broadly neutralizing antibodies to date

Researchers isolated a large panel of broadly neutralizing antibodies from COVID-19 recovered-vaccinated donors.

10 Mar 2022

Study reveals differential blood glycoprotein profiles in symptomatic and asymptomatic COVID-19 patients

A new study used glycoprotein profiling technology platform that couples high-resolution LC-MS for glycoprotein analysis in regards to COVID-19.

9 Mar 2022

CRIPSR identifies cell-type-specific ACE2 modifiers

Researchers compile a list of candidate genes to identify the surface abundance of functional regulators of ACE2.

9 Mar 2022

Low SARS-CoV-2 diabetogenicity found in infected human pancreatic cells in vitro

Researchers assessed the diabetogenic potential of SARS-CoV-2 in a single cell in vitro analysis on the pancreatic islet cells.

9 Mar 2022

How will mutations change the SARS-CoV-2 spike protein in the future?

A new Cells review discusses the factors that affect the function of the SARS-CoV-2 S protein and provides theoretical limits of this viral protein.

8 Mar 2022

Study evaluates heterologous vaccination scheme in children using two SARS-CoV-2 RBD protein vaccines

A recent study predicted the efficacy of the SOBERANA 02 and SOBERANA Plus COVID-19 vaccines in children.

8 Mar 2022

A promising approach for COVID-19 prophylaxis

SARS-CoV-2 viruses can hide from recognition by the immune system. However, the antiviral immune receptor RIG-I can be stimulated, which improves protection against lethal SARS-CoV-2 infections.

8 Mar 2022

SARS-CoV-2 spike protein characteristics responsible for viral evolution in human hosts

Researchers directly compared the pre-fusion spikes of SARS-CoV-2 Alpha and Beta variants with the original Wuhan strain and the D614G-only variant.

8 Mar 2022

Omicron-based vaccine candidate generated to assess whether immunogenicity could be further improved

Researchers developed a vaccine candidate termed Ad26.COV2.S.529, encoding a stabilized Omicron-based S protein resembling ancestral SARS-CoV-2 Wuhan-Hu-1 S protein.

8 Mar 2022

Identification of a rapid test for SARS-CoV-2 neutralization via antibodies and nanobodies

Researchers presented a technique called rapid in vitro inhibition assay (RIVIA), whereby potential SARS-CoV-2 antibody and nanobody candidates can be rapidly screened.

8 Mar 2022

How have human organoids been used in research to study SARS-CoV-2?

In a recent review published in the journal Organoids, scientists have presented an overview on the use of human stem cell-derived organoids in understanding functionality and cellular tropism of severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2), a deadly beta-coronavirus responsible for the ongoing coronavirus disease 2019 (COVID-19) pandemic.
