what is the location and function of microglia?
Microglia are a type of neuroglia, or glial cell, that are found in the central nervous system (CNS), including the brain and spinal cord. They are the resident immune cells of the CNS and play a key role in immune defense and surveillance.
Microglia are involved in various functions, including phagocytosis (engulfing and digesting cellular debris, pathogens, and dead neurons), antigen presentation, and the production of inflammatory and anti-inflammatory molecules. They also play a role in synaptic pruning and sculpting during development, as well as modulating neuroinflammation in response to injury or disease. Overall, microglia help to maintain the health and function of the nervous system.
