GluT4: A central player in hippocampal memory and brain insulin resistance.

GluT4: A central player in hippocampal memory and brain insulin resistance. Exp Neurol. 2019 Oct 12;:113076 Authors: McNay EC, Pearson-Leary J Abstract Insulin is now well-established as playing multiple roles within the brain, and specifically as regulating hippocampal cognitive processes and metabolism. Impairments to insulin signaling, such as those seen in type 2 diabetes and Alzheimer's disease, are associated with brain hypometabolism and cognitive impairment, but the mechanisms of insulin's central effects are not determined. Several lines of research converge to suggest that the insulin-responsive glucose transporter GluT4 plays a central role in hippocampal memory processes, and that reduced activation of this transporter may underpin the cognitive impairments seen as a consequence of insulin resistance.
