Abstract

The Meffert lab studies mechanisms by which programs of gene expression are synchronously coordinated and maintained to underly enduring changes in brain function.  One focus of our research investigates the upstream post-transcriptional processes, coordinated by RNA-binding proteins and non-coding RNA, that can orchestrate the subcellular control of genes required to accurately alter synapse growth and excitation.  We leverage discoveries of molecular gene control mechanisms in settings of disease of the nervous system, including autism and chronic pain, with the goal of uncovering potential therapeutic targets.
