Based on your understanding of this cell’s function, you might expect this cell to be active in neurodegenerative disorders like alzheimers where this cell removes damaged neurons. additionally, this cell is active in preventing encephalitis and meningitis due to its ability to phagocytize microorganisms.

Microglial cell

Explanation:

The microglial cells are macrophages that are in the central nervous system (brain and spinal cord) protecting it. This cells will phagocytize damaged neurons as when a person has Alzheimer as well as agents that can cause a potential damage to the central nervous system such as the meningitis virus. When the Microglial cells phagocytize they absorb the damaged neuron or antigen and then they destroy it.
