Synaptogenesis
Synapses are specialized asymmetric cell-cell connections permitting the controlled transfer of an electrical or chemical signal between a presynaptic neuronal cell and a postsynaptic target cell (e.g. neuron or muscle). Adequate synapse function is an essential prerequisite of all neuronal processing, including higher cognitive functions, such as learning and memory. At synapses, neurotransmit...
متن کاملSynaptogenesis.
Synaptogenesis is a process involving the formation of a neurotransmitter release site in the presynaptic neuron and a receptive field at the postsynaptic partners, and the precise alignment of pre- and post-synaptic specializations. In C. elegans synapses are found as en passant axonal swellings along the nerve processes. Genetic screens using a synaptic vesicle-associated GFP marker have iden...
متن کاملGlial Control of Synaptogenesis
Though all communication between neurons occurs through synapses, we know surprisingly little about the mechanisms inducing their formation. In this issue of Cell, Barres and colleagues (Christopherson et al., 2005) demonstrate that glial-derived thrombospondins and additional soluble glial-secreted factors regulate synapse assembly and functional maturation.
متن کاملMechanisms of vertebrate synaptogenesis.
The formation of synapses in the vertebrate central nervous system is a complex process that occurs over a protracted period of development. Recent work has begun to unravel the mysteries of synaptogenesis, demonstrating the existence of multiple molecules that influence not only when and where synapses form but also synaptic specificity and stability. Some of these molecules act at a distance,...
متن کاملRole for glia in synaptogenesis.
Nearly one-half of the cells in a human brain are astrocytes, but the function of these little cells remains a great mystery. Astrocytes form an intimate association with synapses throughout the adult CNS, where they help regulate ion and neurotransmitter concentrations. Recent in vitro studies, however, have found that astrocytes also exert powerful control over the number of CNS synapses that...
