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 ...

Many diseases arise from abnormalities in our capillaries, tiny exquisitely branching blood vessel networks that play a critical role in tissue health. Researchers have learned a lot about the ...

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 ...

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 ...

It’s essential for bones to be connected to the circulatory system, but little is known about how circulation works in that part of the body. Scientists do know that if a drug is injected into a bone, ...

While the behavior of blood cells flowing within single, straight vessels is a well-known problem, less is known about the individual cellular-scale events giving rise to blood behavior in ...

Scientists in Japan say they have made a critical step forward in kidney regeneration. A team from Hiroshima University, Kumamoto University, and Juntendo University School of Medicine have shown that ...

New research has uncovered that capillaries have the capacity to both sense brain activity and generate an electrical vasodilatory signal to evoke blood flow and direct nutrients to neurons. All it ...
