SUMMARY:HDR - Alexandre Favereaux
DESCRIPTION:MicroRNAs et plasticité neuronale : de la physiologie à la pathologie. \n\n Since 2005\, my research activity has principally focused on the regulation of neuronal gene expression by microRNAs (miRNAs). miRNAs are small non-coding RNAs that inhibit protein translation by binding to the 3′ untranslated region (3′ UTR) of target mRNAs. miRNAs are abundant in the brain\, with the challenge being to identify their roles and targets in specific neuronal functions.\nWe first demonstrated that miRNAs are key regulator of gene expression in the context of chronic neuropathic pain\, with a tremendous therapeutic potential.\nIn a second study\, we showed that miRNAs are also involved in cancer-related pain mechanisms and that miRNAs can be used as analgesic drugs.\nIn physiological conditions\, miRNAs are also important regulators of synaptic protein expression. We recently showed that miRNAs regulate AMPA receptors expression during synaptic plasticity such as the homeostatic scaling paradigm.\nFinally\, my new project is based on the hypothesis that\, in addition to classical synaptic communication\, neurons are able to communicate through the exchange of RNAs shuttled between cells in extracellular vesicles called exosomes. \nPublications \nLetellier M\, Elramah S\, Mondin M\, Soula A\, Penn A\, Choquet D\, Landry M\, Thoumine O\, Favereaux A. miR-92a regulates expression of synaptic GluA1-containing AMPA receptors during homeostatic scaling.
