In Alzheimer’s disease, blood flows sluggishly through the brain, partly because Aβ provokes small blood vessels to constrict. In the June 20 Science, researchers led by David Attwell at University ...

A gene variant found more often in people who live past 100 has reversed key markers of cardiac aging in laboratory tests on ...

Researchers have built a 3D human blood-brain barrier in the lab and discovered a key role of brain pericytes in cerebral malaria disease Cerebral malaria is a deadly complication of Plasmodium ...

Pulmonary arterial hypertension (PAH) is a rare condition that's difficult to treat. The hallmarks of the disease—narrowing of the arterioles and capillaries that deliver blood to the lungs—force the ...

Leiden researchers found a way to measure the tiny forces exerted by pericytes, one of the most elusive, hard to research cell types, which occur in tiny blood vessels. Building on this fundamental ...

Depending on whom you ask, pericytes are either vital vascular regulators that boost blood flow to needy areas of the brain, or mere bystanders that let other cells take on that job. A new study ...

Discovering the role of pericytes in the blood-retinal barrier suggesting pathogenetic insights into diabetic retinopathy, outlines a new report. Inside the eye, at the interface between blood vessels ...

Pericytes are a type of cells found in the brain's blood vessels. Using advanced imaging technique, it was found that these cells grow even in the empty spaces when the pericytes die, reveals a new ...

A team of scientists from the United States has recently conducted a study using pericyte-like cell-containing brain cortical organoids as an experimental model to investigate the impact of severe ...

Pericytes wrap around endothelial cells and have important roles in supporting the growth and maintenance of blood vessels. Previous work indicated that venular pericytes facilitate the initial ...

Extended periods of limb immobilization -- whether from long-term bed rest, casting, spaceflight, or other circumstances -- can reduce skeletal muscle mass and strength to the extent that recovery is ...
