The crosstalks between vascular endothelial cells, vascular smooth muscle cells, and adventitial fibroblasts in vascular remodeling.

Abstract

Pathological vascular remodeling (VR) is characterized by structural and functional alterations in the vascular wall resulting from injury, which significantly contribute to the development of cardiovascular diseases (CVDs). The vascular wall consists primarily of endothelial cells (ECs), vascular smooth muscle cells (VSMCs), and adventitial fibroblasts (AFs), whose interactions are crucial for both the formation of the vascular system and the maintenance of mature blood vessels. Disruptions in the communication between these cell types have been implicated in the progression of VR. This review examines the complex interactions between ECs, VSMCs, and AFs in the context of CVD development, emphasizing a relatively underexplored yet potentially critical mechanism. This interaction framework likely extends to the broader cellular dialogue in the pathogenesis of CVDs, suggesting novel therapeutic strategies for intervention.
