Often called microglia, brain immune cells act as the central nervous system’s dedicated defense force. They constantly scan for pathogens, clear cellular debris, and prune outdated synaptic connections to maintain neural health. Researchers leverage these cells to study neuroinflammation and develop therapies for conditions like Alzheimer’s, multiple sclerosis, and traumatic brain injury. Ultimately, patients with neurological disorders, as well as aging populations seeking cognitive resilience, benefit most from this vital research.
