During sterile inflammation, emigrating leukocytes sequentially engage subsets of pericytes associated with blood vessels and acquire adhesive, migratory and survival signals. Figure 1: Two types of ...

Figure 1: Pericytes sense inflammation and interact with cells of the innate immune system during interstitial migration. Figure 2: The interaction of myeloid leukocytes with NG2 + pericytes during ...

Pericytes—dainty little cells that decorate the brain’s smallest blood vessels— are drawing growing research interest, and controversy. For one, whether these cells help control cerebral blood flow ...

A new study reveals the crucial role of vascular system cells -- known as pericytes -- in the formation of long-term memories of life events -- memories that are lost in diseases such as Alzheimer's ...

A recent study reveals that SARS-CoV-2 may damage blood vessels without infecting cells directly. A recent study reveals the details of how SARS-CoV-2 affects pericytes, a cell type critical for the ...

Pericytes are a type of cells found in the brain's blood vessels. Using advanced imaging technique, it was found that these cells grow even in the empty spaces when the pericytes die, reveals a new ...

Discovering the role of pericytes in the blood-retinal barrier suggesting pathogenetic insights into diabetic retinopathy, outlines a new report. Inside the eye, at the interface between blood vessels ...

In the healthy central nervous system, blood flows where neurons need it most. Now, researchers led by Adriana Di Polo at the University of Montreal help explain why. In the August 12 Nature, they ...

Of all the body’s organs, the brain is the most like Area 51: Entry to the region is severely restricted, thanks to a barricade of cells and molecules known collectively as the blood-brain barrier.

Inside the eye, at the interface between blood vessels and the retina, lies a boundary that prevents harmful substances present in the blood from entering the retina. Researchers at the Center for ...
