In celiac disease, one pathway that allows fragments of gliadin protein to get past the intestinal epithelium and subsequently trigger an protease-activated receptor 2 ( PAR2 ) in the intestinal epithelium.

When a host consumes a tissue cyst ( containing bradyzoites ) or an oocyst ( containing sporozoites ), the bradyzoites or sporozoites stage-convert into tachyzoites upon infecting the intestinal epithelium of the host.
34.
Tight junctions in the intestinal epithelium are also known to be size-selective, such that large molecules ( with molecular radii greater than about 4.5 & # 8491; ) are excluded.
35.
The parasites first invade cells in and surrounding the intestinal epithelium, and inside these cells, the parasites differentiate into tachyzoites, the motile and quickly multiplying cellular stage of " T . gondii ".
36.
Osteonectin has been localized in a variety of tissues, but is found in greatest abundance in osseous tissue, tissues characterized by high turnover ( such as intestinal epithelium ), basement membranes, and certain neoplasms.
37.
The normal test will result in a higher amount of the radiolabeled cobalamin in the urine because it would have been absorbed by the intestinal epithelium, but passed into the urine because all hepatic B12 receptors were occupied.
38.
Protection of these stem cells is essential for long-term maintenance of the intestinal epithelium, and the location of Paneth cells adjacent to stem cells suggests that they play a critical role in defending epithelial cell renewal.
39.
Larger molecules may also pass the intestinal epithelium via the paracellular pathway, although at a much slower rate and the mechanism of this transport via a " leak " pathway is unknown but may include transient breaks in the epithilial barrier.

He then identified the Wnt signal-enhancing Rspondins as ligands of Lgr5, and exploited the Rspondin / Lgr5 axis to develop a 3D organoid culture system for indefinite expansion of normal intestinal epithelium starting from a single adult Lgr5 stem cell.
