Epithelial Cell Shedding and Barrier Function
The intestinal epithelium is a critical component of the gut barrier. Composed of a single layer of intestinal epithelial cells (IECs) held together by tight junctions, this delicate structure prevents the transfer of harmful microorganisms, antigens, and toxins from the gut lumen into the circulation. The equilibrium between the rate of apoptosis and shedding of senescent epithelial cells at t...

متن کاملAugmenting Epithelial Barrier Function
The simplest multicellular animal organisms, coelenterates, are essentially floating intestines in the sea. More fundamentally, they are ‘barrier tubes’ that attempt to compartmentalize the environment they exist in. It is said that ontogeny recapitulates phylogeny. It is thus interesting that the blastocyst, among the earliest multicellular embryonic structures, is essentially a sac comprised ...
متن کاملProbiotic bacteria and intestinal epithelial barrier function.
The intestinal tract is a diverse microenvironment where more than 500 species of bacteria thrive. A single layer of epithelium is all that separates these commensal microorganisms and pathogens from the underlying immune cells, and thus epithelial barrier function is a key component in the arsenal of defense mechanisms required to prevent infection and inflammation. The epithelial barrier cons...
متن کاملEpithelial cell kinase-B61: an autocrine loop modulating intestinal epithelial migration and barrier function.
Epithelial cell kinase (Eck) is a member of a large family of receptor tyrosine kinases whose functions remain largely unknown. Expression and regulation of Eck and its cognate ligand B61 were analyzed in the human colonic adenocarcinoma cell line Caco-2. Immunocytochemical staining demonstrated coexpression of Eck and B61 in the same cells, suggestive of an autocrine loop. Eck levels were maxi...
