Dendritic morphology is typically highly branched,and the branching and synaptic abundance of dendrites can enhance the receptive range of neurons and the diversity of information received,thus providing the basis for information processing in the nervous system.Once dendritic development is aberrantly compromised or damaged,it may lead to abnormal connectivity of the neural network,affecting the function and stability of the nervous system and ultimately triggering a series of neurological disorders.Research on the regulation of dendritic developmental processes has flourished,and much progress is now being made in its regulatory mechanisms.Noteworthily,dendrites are characterized by an extremely complex dendritic arborization that cannot be attributed to individual protein functions alone,requiring a systematic analysis of the intrinsic and extrinsic signals and the coordinated roles among them.Actin cytoskeleton organization and membrane vesicle trafficking are required during dendrite development,with actin providing tracks for vesicles and vesicle trafficking in turn providing material for actin assembly.In this review,we focus on these two basic biological processes and discuss the molecular mechanisms and their synergistic effects underlying the morphogenesis of neuronal dendrites.We also offer insights and discuss strategies for the potential preventive and therapeutic treatment of neuropsychiatric disorders.
