Translational Insights Into Pericyte-Mediated Regulation of Cerebral Blood Flow: Implications for Ischemic Stroke.

Abstract

Microvascular reperfusion stands as a critical therapeutic objective in ischemic stroke management. Pericytes, specialized contractile mural cells enveloping cerebral capillaries, serve as master regulators of capillary tone and regional hemodynamics, exerting a profound influence on post-ischemic stroke blood flow dynamics. Despite their pivotal role in microcirculatory control, there are limited therapeutic targets specifically aimed at regulating their activity. Here, we summarize the multifaceted roles of pericytes in ischemic stroke and discuss various pericyte-related strategies for ischemic stroke. While these interventions offer some benefits, they also present notable limitations, including adverse reactions, structural instability, suboptimal efficacy, and challenges in clinical translation. Future efforts directed toward deciphering the spatiotemporal responses of pericytes across different ischemic phases and achieving their selective and effective regulation are expected to yield novel strategies for precision microcirculatory rehabilitation.
