Sexually Dimorphic Effects of Nociceptor LKB1 on Mitochondrial Metabolism and Mechanical Allodynia After Fasting.
Abstract
Pain induces metabolic stress in pain sensing neurons (nociceptors); alleviating this stress represents an avenue for treating pain. Liver kinase B1 (LKB1) is involved in maintaining energy homeostasis and is a key mediator of the cellular response to metabolic stress. If cellular energy modulation and pain relief is LKB1-dependent, then its removal could lead to metabolic imbalance and innocuous stimuli becoming painful (allodynia).
