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.

Antibody response following SARS-CoV-2 mRNA vaccine is greater than natural infection

Researchers in the United States have provided the first evidence that messenger RNA (mRNA)-based vaccines against severe acute respiratory coronavirus 2 (SARS-CoV-2) induce a broader array of antibody subtypes against the viral spike protein than natural infection does.

Sacubitril/valsartan drug did not significantly reduce cardiovascular death after heart attack

The heart failure drug sacubitril/valsartan did not significantly reduce the rate of heart failure or cardiovascular death following a heart attack compared to ramipril, an angiotensin-converting enzyme (ACE) inhibitor proven effective in improving survival following heart attacks.

Farxiga approved in the US for the treatment of chronic kidney disease in patients at risk of progression with and without type-2 diabetes

Approval is the most significant advancement in the treatment of chronic kidney disease in more than 20 years. In DAPA-CKD Phase III trial, Farxiga demonstrated unprecedented reduction in the risk of the composite of worsening of renal function, end-stage kidney disease and cardiovascular or renal death.

A look at how coronavirus disease (COVID-19) affects Parkinson's

Earlier, herpes simplex virus (HSV), influenza virus A, measles virus, cytomegalovirus (CMV), and mumps virus have all been associated with after-effects of the virus that includes Parkinson's disease (PD). This list may now include SARS-CoV-2.

A SARS-CoV-2 ferritin nanoparticle vaccine elicits broad immunity

In a recent bioRxiv* preprint research paper, M. Gordon Joyce et al. designed engineered nanoparticle immunogens that recapitulate the structural and antigenic properties of prefusion Spike (S), S1 and receptor-binding domain (RBD). They demonstrated that these immunogens induced robust S-binding, ACE2 (angiotensin-converting enzyme)-inhibition, and authentic and pseudovirus neutralizing antibodies against SARS-CoV-2 in mice.

The "key" to vaccine development depends on virus’ binding to human cells

New variants of the SARS-CoV-2 virus most likely will necessitate the development of more vaccine options in the years ahead, and a biomedical scientist at Iowa State University believes the "key" to that development lies in the way the virus binds to human cells.
