However, their function in key regulators of energy homeostasis control is not well understood and is completely unexplored in females.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods and results<\/jats:title><jats:p>Mice lacking neurons expressing the sodium channel Nav1.8 were generated using an ablation strategy based on cre recombinase\u2010mediated expression of diphtheria toxin fragment A (DTA) (Nav1.8\u2010cre\/DTA mice) to investigate whether these neurons modulate body weight, food intake, gut hormone secretion, gastrointestinal transit, and glucose tolerance in response to nutrient challenges in a sex\u2010dependent manner. Male Nav1.8\u2010cre\/DTA mice show resistance to gain weight in response to high\u2010fat high\u2010sugar diet (HFHSD), whereas females lacking Nav1.8+ neurons have improved oral glucose tolerance accompanied by higher insulin levels and attenuated glucagon secretion after an oral glucose load. Female Nav1.8\u2010cre\/DTA mice also show higher fasting and postprandial glucagon like peptide\u20101 (GLP\u20101) levels with an increased number of GLP\u20101\u2010positive cells.
