This important study examines the role of pericytes in patterning the zebrafish blood-brain barrier (BBB) and controlling its permeability. Using pdgfrb mutant zebrafish models lacking brain pericytes ...

The tiny plastic particles are gobbled up by immune cells, travel through the bloodstream and eventually become lodged in blood vessels in the brain. It’s not clear whether such obstructions ...

For the first time, scientists have used real-time imaging to track tiny pieces of microplastics as they moved through the brain blood vessels of mice. In experiments, the international team of ...

For the first time, however, experts succeeded in visually tracking the movement of microplastics through brain blood vessels in mice—and the pile-ups resembled a microscopic “car crash.” ...

When military personnel fire certain powerful weapons, they may be exposed to blast waves that damage blood vessels in the brain. Blasts from military weapons may injure the brain through its ...

They found a new way in which microplastics may disrupt blood vessels and brain health, without crossing from the bloodstream to the brain. Microplastics are tiny particles of plastic, that break ...

This "tsunami in the body" is one way a blast can injure blood vessels that supply oxygen and nutrients to structures deep in the brain, says Dr. Ibolja Cernak, an expert on blast injuries at ...
