All it takes is the flip of a protein "switch" within the tiny wire-like capillaries of the brain to increase the blood flow that ensures optimal brain function. New research has uncovered that ...

Cerebral blood delivery depends on mechanisms such as electrical signaling, which propagates through capillary networks to upstream arterioles to deliver blood, and calcium signaling, which fine-tunes ...

Burlington, Vt.— A team of UVM scientists led by Mark Nelson, Ph.D., from the Larner College of Medicine at the University of Vermont, has uncovered a novel mechanism that reshapes our understanding ...

A study discovered that three major proinflammatory mediators -- interlukin-1 beta, tumor necrosis factor alpha, and thrombin -- individually and especially when combined, directly drive capillary ...

New research on tiny capillaries and cells called pericytes details how blood moves through over 400 miles of total vasculature in the human brain. While the human brain has over 400 miles of total ...
