Stevens will present new work on the role of brain immune cells called microglia in the regulation of synapses — the junctions between neurons — and, ultimately, in autism.
Here’s how Stevens describes what she’ll discuss:
"Emerging evidence indicates that microglia, immune cells that reside in the brain, are altered in some individuals with autism, but it is not yet known whether they play a direct role. Are microglia simply responding to changes in the brain environment? Or could they play an active or even causal role in autism?
"Understanding their normal function in brain development is providing important insight. Work from our laboratory over the past couple of years has demonstrated a surprising new role for microglia and molecules traditionally associated with innate immune system function in elimination and refinement of central nervous system synapses.
"In my talk, I will present evidence that microglia actively participate in synaptic pruning by engulfing, or phagocytosing, developing synapses. Our recent studies support a model in which the immune system tags ‘weaker’ or less active synapses in the developing brain, and then microglia eliminate those synapses. Our findings have important implications for understanding mechanisms underlying synaptic dysfunction in autism, Rett syndrome and other neurodevelopmental disorders."
