Can SARS-CoV-2’s impairment of endothelium cause vascular disease? The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the pathogen that causes the coronavirus disease (COVID-19), contains the spike protein that binds with the human angiotensin-converting enzyme 2 (ACE2) receptor to enter and infect host cells. Researchers in the U.S. and China have revealed that SARS-CoV-2's spike protein does not only latch and bind to healthy cells for infection, but also plays a key role in the disease process. The study, published in the journal Circulation Research, suggests that COVID-...

Fasting lowers blood pressure by reshaping the gut microbiota Nearly half of adults in the United States have hypertension, a condition that raises the risk for heart disease and stroke, which are leading causes of death in the U. S. At Baylor College of Medicine, Dr. David J. Durgan and his colleagues are dedicated to better understand hypertension, in particular the emerging evidence suggesting that disruption of the gut microbiota, known as gut dysbiosis, can have adverse effects on blood pressure. The human gastrointestinal tract is home of the gut microbiota, a large community of resi...
