The intestinal epithelium serves as an essential interface between the host and microbiota, regulating innate adaptive immunity, absorption of nutrients systemic metabolism, mediating bidirectional communication with nervous system. suffers constant challenges to proteostasis machinery due its exposure dynamically changing microbial laden lumenal gut environment high secretory demand placed on multiple epithelial cell types accommodate physiology-especially goblet, enteroendocrine Paneth cells. In all cases, cells require active unfolded protein response (UPR) sustain their physiological function, main pathway that monitors adjusts function changes in environment. A specialised endoplasmic reticulum (ER) stress sensor uniquely expressed lining mucosal surfaces, termed inositol-requiring transmembrane kinase/endoribonuclease β, has specific roles homeostasis, mucus production microbiota. Chronic ER or genetic mutations affecting key UPR mediators contribute occurrence inflammatory bowel disease ulcerative colitis, addition colon cancer. Here, we review recent advances linking physiology disease. Therapeutic strategies alleviate enforce improve ageing diseases are also discussed.

Gut health is crucial in many ways, such as improving human general and enhancing production agricultural animals. To maximize the effect of a healthy gastrointestinal tract (GIT), an understanding regulation intestinal functions needed. Proper depend on activity, composition, behavior epithelial cells (IECs). There are various types IECs, including enterocytes, Paneth cells, enteroendocrine (EECs), goblet tuft M stem (IESCs), each with unique 3D structures IEC distributions. Although communication between IECs other cell types, immune neurons, has been intensively reviewed, different rarely addressed. The present paper overviews networks among that influence functions. Intestinal absorption regulated by incretins derived from EECs induce nutrient transporter activity enterocytes. EECs, enterocytes release signals to activate Notch signaling, which modulates IESC homeostasis, proliferation differentiation. immunity can be altered via cytokines IECs. Finally, tools for investigating have discussed, novel model utilizing enteroids considered powerful tool research. Overall, importance communication, especially cover most functional regulating pathways, overviewed this paper. Such compilation will helpful developing strategies maintaining gut health.
