Dendrite development
Neurons extend elaborate dendrites studded with spines. Unexpectedly, this cellular sculpting is regulated by the origin recognition complex -- the core machinery for initiating DNA replication.
متن کاملThe Control of Dendrite Development
Dendrite development is an important and unsolved problem in neuroscience. The nervous system is composed of a vast number of neurons with strikingly different morphology. Neurons are highly polarized cells with distinct subcellular compartments, including one or multiple dendritic processes arising from the cell body, and a single, extended axon. Communications between neurons involve synapses...
متن کاملMolecular control of cortical dendrite development.
Dendritic morphology has a profound impact on neuronal information processing. The overall extent and orientation of dendrites determines the kinds of input a neuron receives. Fine dendritic appendages called spines act as subcellular compartments devoted to processing synaptic information, and the dendritic branching pattern determines the efficacy with which synaptic information is transmitte...
متن کاملMolecules and mechanisms of dendrite development in Drosophila.
Neurons are one of the most morphologically diverse cell types, in large part owing to their intricate dendrite branching patterns. Dendrites are structures that are specialized to receive and process inputs in neurons, thus their specific morphologies reflect neural connectivity and influence information flow through circuits. Recent studies in Drosophila on the molecular basis of dendrite div...
متن کاملDendrite development regulated by CREST, a calcium-regulated transcriptional activator.
The lasting effects of neuronal activity on brain development involve calcium-dependent gene expression. Using a strategy called transactivator trap, we cloned a calcium-responsive transactivator called CREST (for calcium-responsive transactivator). CREST is a SYT-related nuclear protein that interacts with adenosine 3',5'-monophosphate (cAMP) response element-binding protein (CREB)-binding pro...
