Regulation of dendritic development by neuronal activity.
Proper development of dendrites is essential for the establishment of neuronal circuitry. The elaboration of the dendritic tree is a highly dynamic and regulated process, which involves the formation of new branches as well as the maintenance or elimination of pre-existing branches. This review describes recent advances in our understanding of the molecular mechanisms of activity-dependent dendritic development. Neuronal activity triggers calcium-mediated signaling events that affect the structural components of dendrites and adhesion molecules. These calcium-induced signaling pathways also target nuclear transcription factors thereby controlling expression of genes required for dendritic development. Thus, a coordinated response to calcium-regulated signaling pathways mediates activity-dependent dendritic development.
