Synaptic pruning and autism

WebSep 9, 2016 · The intimate relationship between LTD and synaptic pruning enables circuit plasticity in the developing and mature brain, and it therefore is also of interest in developmental brain disorders, such as autism. Indeed, synaptic dysfunction and abnormal synaptic pruning are characteristic features of ASD (for review, see refs. 15, 113). WebImpairments in synaptic pruning disrupt the excitatory versus inhibitory balance (E/I balance) of synapses, which may cause neurodevelopmental disorders such as autism spectrum disorder (ASD). Recent studies have determined molecular mechanisms by which microglia, the brain's resident immune cells, engulf inappropriate and less active synapses.
