microglia
Microglia are specialized GLIAL CELLS of the CENTRAL NERVOUS SYSTEM that act as resident IMMUNE CELLS, protecting the brain and spinal cord through PHAGOCYTOSIS and immune surveillance.
Microglia are small NEUROGLIAL CELLS derived from MYELOID PROGENITOR CELLS that serve as the primary immune defense cells of the CENTRAL NERVOUS SYSTEM. They continuously monitor the neural environment, remove damaged NEURONS, cellular debris, and pathogens through PHAGOCYTOSIS, and regulate NEUROINFLAMMATION by releasing signaling molecules such as CYTOKINES. Microglia play important roles in BRAIN DEVELOPMENT, SYNAPTIC PRUNING, tissue repair, and responses to NEURODEGENERATIVE DISEASES such as ALZHEIMER DISEASE.
Microglia are the immune defense cells of the brain and spinal cord that protect nervous tissue by removing harmful substances and damaged cells.
• Microglia are the immune cells of the central nervous system. • They are found in the brain and spinal cord. • They protect nervous tissue from infection and injury. • They remove damaged cells and waste materials through phagocytosis. • They help control inflammation in the nervous system. • They support brain development by removing unnecessary connections between neurons. • Abnormal microglial activity is linked with several brain disorders.
