Cerebral Vascular Smooth Muscle Cells is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
This page provides comprehensive information about the cell type. See the content below for detailed information.
Cerebral vascular smooth muscle cells (vSMCs) line the walls of arterioles, arteries, and larger cerebral vessels. They are essential for cerebrovascular function, blood flow regulation, and maintenance of the blood-brain barrier. Dysfunction of vSMCs contributes to vascular cognitive impairment and neurodegenerative diseases.
