The virus infects the gut cells of the beetles, which subsequently disseminate the infection by excreting virus at feeding and breeding sites.

Possibly, most effects of lectins are due to gastrointestinal distress through interaction of the lectins with the gut epithelial cells.

Beneficial flora increase the gut's absorption of water, reduce counts of damaging bacteria, increase growth of human gut cells, and stimulate growth of indigenous bacteria.

An ocular grid (Leitz code No. 519902), to count the fluorescent gut cells, was moved systematically along the villous epithelium and the typical flattened goblet cell depleted follicle associated epithelium of Peyer's patches domes.

Evidence is accumulating to show that gut epithelial cells interact closely with adjacent mononuclear cells.

Malabsorption occurs because of the destruction of gut cells called enterocytes.

Omeprazole works differently, inhibiting the enzyme that pumps acid out of gut cells regardless of what stimulates acid production.

Heme is retained in the peritrophic matrix, a layer of protein and polysaccharides that covers the midgut and separates gut cells from the blood bolus.

Zinc stimulates metallothionein, a protein in gut cells that binds copper and prevents their absorption and transport to the liver.

It is abundant in the gut secretory cells and in the pancreas where it co-localises with glucagon.
