Protein Imbalance Linked to Autism-Like Behavior
Summary: A new study finds that autism-like behaviors appear in mice when two competing neuronal proteins—MDGA2 and BDNF—lose their balance. Under normal conditions, MDGA2 restrains BDNF/TrkB signaling; when MDGA2 levels fall, BDNF/TrkB activity rises, driving increased excitatory neuronal activity and social deficits. Mice with reduced MDGA2 displayed behaviors resembling core features of autism spectrum disorder … Read more
