Lymphoid cells in chicken intestinal epithelium

Cell and Tissue Research, 1975
The intraepithelial lymphoid cells of chicken small intestine were studied by light microscopy using 1 mu Epon sections, and by electron microscopy. Three cell types were found: small lymphocytes, large lymphoid cells, and granular cells. These cells correspond to the theliolymphocytes and globule leucocytes of previous authors. The numbers of all cell

Regulation of intestinal goblet cell secretion. III. Isolated intestinal epithelium

American Journal of Physiology-Gastrointestinal and Liver Physiology, 1984
Cholinergic secretagogues evoke mucus secretion from goblet cells in the crypts of small and large intestinal mucosa in vivo and in organ culture. It was not known whether this response reflected a direct action on epithelial cell receptors or an indirect effect involving intermediate neurons of the enteric nervous system.

Glycosphingolipids and the differentiation of intestinal epithelium

Experimental Cell Research, 1981
Abstract Changes in lipid-bound cell surface carbohydrates during cell differentiation were studied in epithelial cells of rat small intestine (crypt and villus tip cells). The identity of the cells was established by morphological and enzymatic criteria. Acid and non-acid glycosphingolipids were analysed by thin-layer chromatography, with a separate

Enteroendocrine Cells: Chemosensors in the Intestinal Epithelium

Annual Review of Physiology, 2016
The enteroendocrine system orchestrates how the body responds to the ingestion of foods, employing a diversity of hormones to fine-tune a wide range of physiological responses both within and outside the gut. Recent interest in gut hormones has surged with the realization that they modulate glucose tolerance and food intake through a variety of ...

Intestinal epithelium responses to titanium dioxide nanoparticles

Nutrition, Metabolism and Cardiovascular Diseases, 2019
Background. Humans are exposed to nanoparticles from a variety of sources through a broad range of exposure ways since nanomaterials are increasingly used in different productive sectors. Titanium dioxide (TiO2) is enclosed in many consumer products including pharmaceuticals, cosmetics, and foods.

Interactions between lipopolysaccharide and the intestinal epithelium

Journal of the American Veterinary Medical Association, 2004
I ischemia often results in endotoxemia, and endotoxemia significantly increases postoperative morbidity and mortality rates in patients with ischemic intestinal disease. Even if all grossly ischemic intestine is resected, remaining intestine may be injured as a result of distention.

Retroviral Gene Transfer into the Intestinal Epithelium

Human Gene Therapy, 1995
The epithelial cells of the gastrointestinal tract may be attractive targets for somatic gene therapy. In these studies, we have used rats and mice to explore the feasibility of gene transfer into the small intestinal epithelium using retroviral vectors.

[Proteus adhesion to intestinal epithelium].

Mikrobiologicheskii zhurnal, 1990
The adhesive properties of Proteus strains isolated from different sources have been studied under conditions similar to the real interaction of microorganisms with the epithelial cells of intestine. A comparison of the adhesive properties of Proteus and of colon Bacillus has shown that the value of the strong adhesion to the mucosa of Proteus isolated

Ancylostoma caninum: Fine structure of intestinal epithelium

Experimental Parasitology, 1969
Abstract A study of the ultrastructure of the intestine of Ancyclostoma caninum reveals several new features: The presence of glycogen, the presence of intramitochondrial crystalloids, the fine structure of pigment granules, and the differences between mid- and hindgut.

Gate-keeper function of the intestinal epithelium

Beneficial Microbes, 2013
There is currently a major focus on the role of the gut barrier function in balancing mucosal immune responses. Increased epithelial permeability for exogenous antigens is a crucial primary or secondary event in the pathogenesis of several disorders affecting body surfaces and beyond. The epithelial gate-keeper function is determined by the individual'
