Maternal insulin resistance multigenerationally impairs synaptic plasticity and memory via gametic mechanisms

Abstract

It’s well known that hippocampal synaptic plasticity and memory are impaired in experimental models of metabolic diseases, however, it is unclear if maternal diet or metabolic alterations around the gestational age may multigenerationally affect learning and memory. In this study, authors demonstrate that maternal high fat diet-dependent insulin resistance affects synaptic plasticity and memory of descendants until the third generation via reduced exon specific brain-derived neurotrophic factor expression in the hippocampus of descendants
