Alzheimer's disease is complicated by poor pericyte function

A poorly functioning blood–brain barrier, in which pericytes play a leading role - special cells surrounding the capillaries of the brain, detains pathogenic proteins in the nervous tissue, which allows the disease to unfold in full force.
