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.

Monoclonal antibody CT-P59 demonstrates potent antiviral efficacy against SARS-CoV-2 delta variant

A Korean study has recently demonstrated antiviral potency of monoclonal antibody CT-P59 against the delta variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The experiments conducted in animals infected with the delta variant have shown that CT-P59 is able to reduce symptom intensity and viral replication in the respiratory tract. The study is currently available on the bioRxiv* preprint server.

More popular type of antihypertensive drugs causes slightly more side effects

Two types of drugs that are recommended as a first treatment for patients with high blood pressure were found equally effective in improving cardiovascular outcomes, but the more popular type causes slightly more side effects, finds a multinational observational study led by researchers at Columbia University Vagelos College of Physicians and Surgeons.

Two types of blood pressure drugs provide equal benefits, but side effects differ

People who are just beginning treatment for high blood pressure can benefit equally from two different classes of medicine - angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) - yet ARBs may be less likely to cause medication side effects, according to an analysis of real-world data published today in Hypertension, an American Heart Association journal.

Researchers discover camelid-derived two nanobodies that target SARS-CoV-2

A new study has been published on the bioRxiv* preprint server, which has identified and characterized two RBD-targeting neutralizing nanobodies, namely, DL4 and DL28.

Synergistic multi-antibody cocktail protects against SARS-CoV-2 in animal model

Researchers in Canada have reported the discovery of a multi-antibody cocktail that synergistically protected against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in an animal model of acute infection.

SARS-CoV-2 reprograms host chromatic network to induce immune dysfunction

A recent study conducted at the University of Texas Science Center, Houston, in the USA, has revealed that upon infection, SARS-CoV-2 alters the host chromatin architecture to suppress antiviral interferon-responsive genes and augment inflammatory genes. The study is currently available on the bioRxiv* preprint server.

Can prior human seasonal coronavirus antibody response patterns predict SARS-CoV-2 inhibition?

A new study, recently released as a preprint on the medRxiv* server, reports the intriguing finding that the cross-neutralizing antibodies elicited by human seasonal coronaviruses (sCoVs) show varying ability to prevent binding between the SARS-CoV-2 spike antigen and its cognate receptor, the angiotensin-converting enzyme 2 (ACE2).

Emerging SARS-CoV-2 mutations L452R & Y453F evade cellular immunity

The study, published in the journal Cell Host & Microbe, also showed emerging mutations L452R and Y453F in the SARS-CoV-2 spike receptor-binding motif evade (HLA) A24-restricted cellular immunity. Meanwhile, the L452R enhances spike stability, viral fusogenicity, and viral infectivity. Hence, the findings suggest that HLA-restricted cellular immunity potentially affects the evolution of viral phenotypes.

Scientist explore conserved RNA elements as potential targets for anti-SARS-CoV-2 drugs

The study, published in the journal Angewandte Chemie International Edition, identified many small molecules that bind to certain parts of the SARS-CoV-2 genome that are less likely altered by mutations using dedicated substance libraries. The scientists derived key functional units and groups in ligands for effective and safe targeting of SARS-CoV-2 RNA.

Study proves effectiveness of Artemisia annua against SARS-CoV-2 in vitro

A multinational research group has been the first to show the excellent activity of artemisinin-based treatment against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in human cell lines – including a specific type of lung cells. Their findings were recently published in the journal Scientific Reports.
