WebDec 7, 2024 · The intestinal epithelium is more than just a physical barrier regulating nutrient uptake, rather it plays a critical role in homeostasis through its intrinsic innate immune function, pivotal regulation of antigen sensitization, and a bi-directional interplay with the microbiota that evolves with age. WebJan 25, 2024 · Intestinal epithelial cells (IECs) emerged as critical modulators of obesity and glucose homeostasis through their effect on lipopolysaccharide (LPS) signaling and decontamination. Furthermore, IECs create a link between microbial metabolites and whole-body metabolic function.
WebApr 4, 2024 · Intestinal epithelial barrier function is closely associated with the development of many intestinal diseases. Heat-killed Lacticaseibacillus paracasei (HK-LP) has been shown to improve intestinal health and enhance immunity. However, the function of HK-LP in the intestinal barrier is still unclear. This study characterized the inflammatory ... WebOct 1, 2024 · The intestinal epithelial cells form a barrier of selective permeability which protects from invasion by the normal bacteria present in the gut. When the barrier is compromised, bacteria and their products can attack the cells and cause inflammation, which can (in severe cases) cause sepsis.
