Immune molecules fine-tune brain circuits

Immune molecules fine-tune brain circuits

Beth Stevens, PhD, has discovered some unexpected synapse eliminators: molecules of the innate immune system, traditionally our first-line defense against infection. Her new findings may help us better understand how neural circuits are fine-tuned—and how they fall apart or form incorrectly in neurological disorders as diverse as Alzheimer’s, glaucoma and epilepsy.
