microglia

Microglia are a type of glial cell found in the brain and spinal cord. They serve as the central nervous system's immune cells, constantly monitoring for signs of injury, infection, or disease. When they detect problems, microglia respond by cleaning up damaged cells and debris, and they can also help regulate inflammation. Think of them as the brain's housekeeping and defense team, ensuring the overall health and proper functioning of neural tissue. Their actions are crucial for maintaining a healthy environment for neurons and supporting brain repair processes.
