MicroRNA regulation of homeostatic synaptic plasticity.
Homeostatic mechanisms are required to control formation and maintenance of synaptic connections to maintain the general level of neural impulse activity within normal limits. How genes controlling these processes are co-coordinately regulated during homeostatic synaptic plasticity is unknown. MicroRNAs (miRNAs) exert regulatory control over mRNA stability and translation and may contribute to ...
متن کاملMicroRNA Regulation of the Synaptic Plasticity-Related Gene Arc
Expression of activity-regulated cytoskeleton associated protein (Arc) is crucial for diverse types of experience-dependent synaptic plasticity and long-term memory in mammals. However, the mechanisms governing Arc-specific translation are little understood. Here, we asked whether Arc translation is regulated by microRNAs. Bioinformatic analysis predicted numerous candidate miRNA binding sites ...
متن کاملCircadian Regulation of Synaptic Plasticity
Circadian rhythms refer to oscillations in biological processes with a period of approximately 24 h. In addition to the sleep/wake cycle, there are circadian rhythms in metabolism, body temperature, hormone output, organ function and gene expression. There is also evidence of circadian rhythms in synaptic plasticity, in some cases driven by a master central clock and in other cases by periphera...
متن کاملRegulation of AMPA receptors and synaptic plasticity.
Neuronal activity controls the strength of excitatory synapses by mechanisms that include changes in the postsynaptic responses mediated by AMPA receptors. These receptors account for most fast responses at excitatory synapses of the CNS, and their activity is regulated by various signaling pathways which control the electrophysiological properties of AMPA receptors and their interaction with n...
