Homogeneity or heterogeneity, the paradox of neurovascular pericytes in the brain.

ABSTRACT: Pericytes are one of the main components of the neurovascular unit. They play a critical role in regulating blood flow, blood-brain barrier permeability, neuroinflammation, and neuronal activity. In the central nervous system (CNS), pericytes are classified into three subtypes, that is, ensheathing, mesh, and thin-strand pericytes, based on their distinct morphologies and region-specific distributions. However, whether these three types of pericytes exhibit heterogeneity or homogeneity with regard to membrane properties has been understudied to date. Here, we combined bulk RNA sequencing analysis with electrophysiological methods to demonstrate that the three subtypes of pericytes share similar electrical membrane properties in the CNS, suggesting a homogenous population of neurovascular p
