Researchers have built the first-ever molecular atlas of the human brain vasculature at single-cell resolution, spanning from early development to adulthood and through disease stages such as brain ...

Hypertension begins harming the brain surprisingly early, even before measurable blood pressure increases. Key cells related to blood vessels, signaling, and myelin maintenance begin aging prematurely ...

The brain is among the most “immune-privileged” of organs primarily through the highly selective permeability of the blood-brain-barrier (BBB), its minimal lymphatic drainage, the presence of ...

Many people who have long COVID—a condition in which health issues persist months after infection—report struggling with “brain fog,” recurring memory and concentration lapses that make it difficult­­ ...

The blood–brain barrier (BBB) is meant to protect the brain from noxious agents; however, it also significantly hinders the delivery of therapeutics to the brain. Several strategies have been employed ...

Enough pints of beer can have you falling off your bar stool or loudly reciting lyrics to early 2000s jams to total strangers, because alcohol can get past one of the strongest defenses in the body.

Leakiness in the brain could explain the memory and concentration problems linked to long COVID. In patients with brain fog, MRI scans revealed signs of damaged blood vessels in their brains, ...

Microplastics in the bloodstream may cause blockages the brain and affect our brain functioning and behavior, according to recent research. Environmental biologists tested the effects of microplastics ...

The properties of the blood-brain barrier serve a vital protective role, but they also keep drugs from reaching the organ. Big pharmaceutical companies have been making deals for technologies that ...
