Vascular Smooth Muscle Cell Contraction Pathway (VSMC Contraction Pathway)

Target
VSMC Contraction Pathway
Molecular classification
Signaling Pathway
01

Overview

The vascular smooth muscle cell (VSMC) contraction pathway is a critical signaling cascade that regulates the contractile state of blood vessels, thereby controlling vascular tone, blood flow, and blood pressure. It involves calcium-dependent and calcium-independent mechanisms, primarily through MLCK and RhoA/ROCK signaling. Dysregulation contributes to hypertension and other cardiovascular diseases.
