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.

Radboudumc researchers find essential mechanism in the disease process of COVID-19

Tobacco use may explain why more men die of coronavirus than women in Spain

Whether or not you are a smoker could condition how the coronavirus affects you. At least that is what numerous researchers are saying, insisting that tobacco use is to blame for the weakened cardiovascular systems which are at greatest risk from COVID-19.

French scientists suggest nicotinic agonists could treat COVID-19

Contrary to the warnings issued by health agencies worldwide against cigarette smoking amid the coronavirus disease (COVID-19), a new paper suggests the possibility that nicotine, a component of tobacco, could prevent coronavirus infection.

Study shows why people with certain heart diseases may be more susceptible to COVID-19

People with certain heart diseases may be more susceptible to worse outcomes with COVID-19, but the reason why has remained unknown.

Gut microbiota could predict severity of COVID-19

The COVID-19 pandemic is spreading to every corner of the world. But not everyone is falling sick at the same rate. A new study published on the preprint server medRxiv in April 2020 suggests that the composition of the gut microbiome could partially explain the difference in susceptibility. This adds a new dimension to what is currently known about the disease.

SARS-CoV-2 readily infects human intestinal cells in a laboratory model

A new Dutch study available on bioRxiv uses differentiated human small intestinal organoids in vitro to demonstrate that intestinal epithelium supports the replication of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and elicits a strong generic immune response.

Rice University looks to ‘trap and zap’ SARS-CoV-2 in wastewater

A team of researchers from Rice University has won a National Science Foundation (NSF) RAPID grant to adapt their wastewater nanotechnology project to help trap and inactivate the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), (which causes COVID-19 disease), in wastewater. This could help public health officials deal with the threat of disease transmission through wastewater.

Goblet cells in the human nasal passage may play key role in enabling COVID-19 infections

Two significant international studies involving hundreds of scientists, including a human geneticist at the Translational Genomics Research Institute (TGen), an affiliate of City of Hope, suggest that specific cells in the human nasal passage shaped like a champagne glass, known as goblet cells, may play a significant role in enabling COVID-19 infections.

Scientists are developing synthetic COVID-19 antibody to treat sick patients

A team of researchers at the Icahn School of Medicine at Mount Sinai, in collaboration with GenScript, is developing a synthetic antibody to SARS-CoV-2, the virus that causes coronavirus disease (COVID-19). This antibody is intended to block the virus from entering human lung cells, and would be another potential treatment option for COVID-19.

SARS-CoV-2 targets specific cells in the lung, nasal passage, and intestine

Now, the researchers from the Massachusetts Institute of Technology (MIT) have identified specific types of cells that are targets of the SARS-CoV-2 that causes the COVID-19 pandemic. The findings of the study published in the journal Cell may help in developing novel therapeutics to combat the deadly viral infection.

RAS inhibitors and COVID-19 severity in hypertensive patients

A new study published in the journal JAMA Cardiology in April 2020 reports that patients with hypertension who are taking medications called ACE inhibitors (ACEI) or ARBs are not at higher risk for death or more severe illness with COVID-19. This conclusion supports current guidelines for the treatment of hypertension during this pandemic.

Study identifies key nose cells as likely COVID-19 virus entry points

Two specific cell types in the nose have been identified as likely initial infection points for COVID-19 coronavirus. Scientists discovered that goblet and ciliated cells in the nose have high levels of the entry proteins that the COVID-19 virus uses to get into our cells.

23 Apr 2020

Scientists identify cells likely targeted by novel coronavirus

Researchers at MIT; the Ragon Institute of MGH, MIT, and Harvard; and the Broad Institute of MIT and Harvard; along with colleagues from around the world have identified specific types of cells that appear to be targets of the coronavirus that is causing the Covid-19 pandemic.

COVID-19 unlikely to be transmitted through semen, study shows

COVID-19 is unlikely to be spread through semen, according to University of Utah Health scientists who participated in an international study of Chinese men who recently had the disease.

COVID-19 and immunodeficiency

COVID-19 disease, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a highly infectious disease. As of today, over 170,000 people worldwide have succumbed to the infection. Reports have shown that some comorbidities and illnesses raise the risk of getting infected and also influence the severity of the disease. Having a compromised immune system can also drastically raise the risk of getting COVID-19.

Role of ACE/ARB inhibitors in the treatment of COVID-19

A new opinion piece published in the journal Circulation Research in April 2020 defends the use of antihypertensive drugs called ACE inhibitors and ARBs in patients with pandemic viral pneumonia called COVID-19.

ACE2 receptor expression by SARS-CoV-2 across different animal species

A new report published on the preprint server bioRxiv in April 2020 reports that several species of animals can be infected with relative ease by the SARS-CoV-2 virus that is the causative agent of the currently raging COVID-19 pandemic. This casts much light on the possible natural hosts and routes of transmission of this virus.

Mutations in novel coronavirus make it more dangerous

A new report published on the preprint server medRxiv in April 2020 reveals that the novel coronavirus SARS-CoV-2 shows the presence of new mutations acquired within infected human cases, which significantly increase its ability to cause human disease.

ACE2-TMPRSS2 profiling indicates tissue vulnerability to SARS-CoV-2 infection

A new study published in April 2020 on the preprint server bioRxiv reports that the different levels of susceptibility of various organs to viral attack by the SARS-CoV-2 virus causing the huge pandemic of COVID-19 sweeping around the world can be predicted from the level of expression of two molecules, the ACE2 receptor, and the TMPRSS2 protein.
