Intestinal epithelial metabolic pathways

Intestinal epithelial metabolic pathways encompass the complex network of biochemical reactions within the gut lining that sustain cellular energy and systemic homeostasis (Rath et al., 2018, PMID: 30115606). These pathways are critical for nutrient absorption, the metabolism of amino acids like glutamine—the primary fuel for enterocytes—and the detoxification of drugs and toxins via the cytochrome P450 system (Zhu et al., 2021, PMID: 34153879). In the context of disease, metabolic reprogramming in enterocytes is a key feature of inflammatory bowel disease (IBD), where a shift from oxidative phosphorylation to glycolysis can compromise barrier integrity and promote inflammation (Aden et al., 2019, PMID: 31611050). While not a single therapeutic target, these pathways are modulated by various pharmacological agents to improve gut health or manage metabolic disorders. For instance, targeting specific transporters or enzymes within these pathways is a common strategy in treating malabsorption and type 2 diabetes (Takiishi et al., 2017, PMID: 28345167). Because this term describes a collection of pathways rather than a specific protein or receptor, it is classified as a broad biological system rather than a discrete therapeutic target.
