Microglia Function

Meaning

Microglia function encompasses the dynamic roles of the central nervous system’s resident immune cells, primarily involving continuous surveillance of the brain microenvironment, phagocytosis of cellular debris, apoptotic cells, and pathogens, and the release of various signaling molecules. These cells are essential for maintaining CNS homeostasis, responding to injury or disease, and actively shaping neural circuits through processes like synaptic pruning during development and plasticity.
