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.

Novel mutation identified in SARS-CoV-2 spike protein from Sweden

Researchers from Sweden and Brazil have identified a novel mutation in a strain of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) obtained from a patient in Stockholm, Sweden, in late April.

Researchers initiate multiple studies to identify coronavirus-related heart problems

COVID-19 is shown to impact the heart and, in some cases, have long-lasting cardiac effects. To discover the extent to which COVID-19 affects the heart, cardiologists and researchers with the University of Miami Miller School of Medicine have begun multiple studies.

SARS-CoV-2 lured away and trapped by a new decoy version of ACE2

Researchers in the United States and Canada have engineered affinity-optimized “receptor traps” that prevent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from binding to and infecting cells.

Novel short ACE2 isoform may influence SARS-CoV-2 susceptibility

A study led by researchers at the University of Southampton, UK, has identified a novel short isoform of the full-length receptor that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) uses to gain entry to host cells.

New bivalent vaccine delivers robust cell-mediated and humoral immunity against SARS-CoV-2

In a groundbreaking bioRxiv study, US researchers demonstrate the capability of next-generation bivalent human adenovirus serotype 5 (hAd5) vaccine for inducing both cellular and humoral immunity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – using both an S protein sequence optimized for cell surface expression and a conserved nucleocapsid antigen designed to be transported to the endosomal subcellular compartment.

Researchers report a liquid biopsy for COVID-19

A new study published on the preprint server medRxiv in July 2020 reports the potential of cell-free DNA as a marker of the severity of disease in COVID-19. This could help triage patients as well as provide a prognostic marker.

Smoking worsens COVID-19 severity, warn researchers

A study conducted by researchers at the University of California, Los Angeles, suggests that smoking increases the risk of more severe lung disease in cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

Loss of smell in COVID-19 explained by scientists

Now, a team of researchers at Harvard Medical school says they have found the reason why some people who get COVID-19 experience loss of smell.

29 Jul 2020

Basigin/CD147 discarded as an accessory SARS-CoV-2 binding receptor

By using specialized assays customized to detect specific receptor interactions, researchers from the Wellcome Sanger Institute in Cambridge UK find no evidence for direct binding of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein to a transmembrane glycoprotein known as basigin.

28 Jul 2020

Emergent SARS-CoV-2 D614G spike mutation more infective due to "open" morphology

Researchers from the Los Alamos National Laboratory and Duke Human Vaccine Institute & Department of Surgery demonstrated that globally prevalent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) with the amino acid substitution D614G in the spike protein is much more infective due to profitable binding encounters with the host receptors.

28 Jul 2020

Computational analyses suggest new pathway for inflammatory response to SARS-CoV-2

Analyses of lung fluid cells from COVID-19 patients conducted on the nation's fastest supercomputer point to gene expression patterns that may explain the runaway symptoms produced by the body's response to SARS-CoV-2.

28 Jul 2020

Cat catches coronavirus from owners

Cases of pet animals contracting the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been reported since the coronavirus disease (COVID-19) first emerged. Now, a pet cat has become the first animal in Britain to test positive after contracting the virus from its owners.

28 Jul 2020

High ACE2 Expression on pancreatic islet cells during inflammation could explain new-onset diabetes in COVID-19

A new study suggests that the SARS-CoV-2 infection may be linked to the onset of diabetes, via the infection of pancreatic islet beta cells, which produce insulin.

27 Jul 2020

Scientists develop COVID-19 test to detect neutralizing antibodies with high sensitivity, specificity

According to a study published in Nature Biotechnology, the sVNT is capable of detecting the functional neutralizing antibodies (NAbs) that can block the binding of the coronavirus spike protein to the angiotensin-converting enzyme 2 (ACE2) host receptor, which mimics the virus-host interaction.

25 Jul 2020

An important SARS-CoV-2 enzyme is responsible for low in vivo antiviral efficacy of hydroxychloroquine

Researchers have shown that hydroxychloroquine interferes with only one redundant pathway that activates the SARS-CoV-2 spike protein.

24 Jul 2020

Study shows interferons do not induce the expression of SARS-CoV-2 cell entry receptor

In a new bioRxiv study, authors identified a isoform of ACE2 (designated as deltaACE2 or dACE2) receptor, shown to be induced in various human cell types.

23 Jul 2020

Common hypertension drugs do not increase risk of severe, fatal COVID-19 infection

A new Northwestern Medicine study in mice found a widely used class of drugs to treat patients with hypertension, cardiovascular disease and diabetic kidney disease - many of whom are elderly -- does not increase the risk of developing a severe and potentially fatal COVID-19 infection, as previously feared.

22 Jul 2020

Mouse model of fatal COVID-19 developed for vaccine and drug testing

Now, a new study published on the preprint server bioRxiv in July 2020 presents an engineered transgenic mouse that reproduces the functional and clinical characteristics of severe human SARS-CoV-2 infection.

21 Jul 2020

Novel blood test for heart failure could lead to new diagnostics for COVID-19 patients

A new blood test that reliably predicts outcomes for heart failure patients could lead to new diagnostics and treatments for COVID-19 patients as well, according to newly published research from cardiologists at the University of Alberta.

20 Jul 2020

More COVID-19 cases where blood type A is common

Now, a new study by researchers at the University of Ulm, Germany, which is published on the preprint server medRxiv in July 2020, focuses on how blood group distribution is related to the mapped dynamics of the epidemic as shown by its geographical distribution.
