Microglia are a type of glial cell that are part of the immune system for the central nervous system. Microglia are small cells that act as phagocytes, clearing components that can threaten the nervous system.
Microglial cells or microglia are the primary and first form of active immune protection in the central nervous system. Microglia are key cells in brain maintenance.
These cells rid the central nervous system of plaque, injury, or neurons and synapses from infection. When we are sleeping, these cells can work properly and optimally.
In addition to cleaning the brain, these cells can also prevent the emergence of Alzheimer's disease. Microglia help remove beta-amyloid, a toxic protein that can be found in the brains of Alzheimer's patients.
