Microglial Cell Activation

Molecular classification
Cellular Process, Immune Response
01

Overview

Microglial cell activation is a dynamic process central both to healthy brain maintenance—via immune defense/debris removal—and pathological conditions when dysregulated chronic inflammation occurs. It involves complex signaling pathways with diverse functional outcomes depending on context-specific cues within the CNS environment.
