Hippocampal demyelination and memory dysfunction are associated with increased levels of the neuronal microRNA miR‐124 and reduced AMPA receptors

Abstract excerpt

OBJECTIVE: Hippocampal demyelination, a common feature of postmortem multiple sclerosis (MS) brains, reduces neuronal gene expression and is a likely contributor to the memory impairment that is found in >40% of individuals with MS. How demyelination alters neuronal gene expression is unknown. METHODS: To explore whether loss of hippocampal myelin alters expression of neuronal microRNAs (miRNAs), we compared...
