What Are Microglia?

The video discusses the role of microglia, a type of glial cell, in the brain. It explains how microglia function as the brain's immune system, compensating for the blood-brain barrier's restriction on immune cells. Microglia are involved in monitoring the brain environment, cleaning up debris, and responding to injuries by activating and multiplying. They also play a role in brain development by pruning synapses and may contribute to neurodegenerative diseases like Alzheimer's. The video concludes with a call to action for viewers to support the channel.
