Astrocyte Activity

Molecular classification
Cellular Process, Homeostatic Mechanism, Signaling Pathway
01

Overview

Astrocyte activity refers to the dynamic physiological and biochemical functions performed by astrocytes, a type of glial cell in the central nervous system (CNS). Astrocytes are star-shaped cells that play essential roles in maintaining CNS homeostasis, supporting neuronal function, regulating synaptic activity, and responding to injury or disease. Key functions include structural support, homeostasis maintenance, metabolic support, blood-brain barrier regulation, neurotransmitter regulation, synaptic modulation, vascular coupling, blood flow regulation, immune response, and injury reaction. Dysregulation of astrocyte activity is implicated in various neurological disorders.
