Commensal-specific immune responses at the intestinal mucosa
The intestinal mucosa harbors a dense community of microbes that breaks down polysaccharides indigestible by the host, synthesizes essential vitamins, stimulates maturation of the immune system, and outcompetes the growth of pathogenic species. In return, the host provides commensals with a habitat …

EFFECTOR T CELL HOMING TO THE SMALL INTESTINAL MUCOSA
The intestinal mucosa, including the intestinal epithelium and underlying lamina propria (LP), contains a large number of effector/memory T cells that are thought to play a central role in the generation and maintenance of mucosal immune responses and in maintaining mucosal integrity. The work in …

Regulation of T cell effector functions in the intestinal mucosa
… regulating differentiation and functionality of intestinal CD4+ and CD8+ T cells. Memory CD4+ T cells is found in the circulation as well as in tissues. In addition to responding to re-infections in an antigen dependent manner these circulating memory CD4+ T cells can produce interferon (IFN)-γ …

The iron-binding proteins of iron-absorbing rat intestinal mucosa
… of radiolabelled ferrous ascorbate into isolated intestinal loops and the determination of mucosal, blood and carcass uptake.

Response of large intestinal mucosa in rats to dietary protein and fat
… rates of cell proliferation of the colon mucosa are associated with the diets high in protein and fat. The objectives of this research were: (1) to determine the pH and ammonia concentrations of the contents in the cecum and different segments of colon in rats fed defined semi-purified …

The demonstration of glucose-6-phosphate phosphatase activity in the intestinal mucosa of the bullfrog Rana catesbeiana (Shaw)
… phosphatase can be demonstrated in frog intestinal mucosa, and the determine the optimum conditions for its study."--Page 6

Phenotype and function of intestinal CD103+ dendritic cells
Mucosal tissues such as the intestine present an enormous surface area to the outside environment and are continually exposed to foreign antigens in food and microflora. Thus, the intestinal mucosa must must remain tolerant to these innocuous antigens while at same time be able to mount effective …

Syntheses of Dimensionally Altered Enzyme Substrates by Means of the Finkelstein Reaction (Benzopurine, Naphthopurine)
… with the enzyme adenosine deaminase from calf intestinal mucosa.

Role of the colonic lymphoglandular complex in mucosal immunity in swine
<p>Colonic lymphoglandular complexes (LGCs) and intestinal mucosa of conventional postweaning pigs were analyzed by flow cytometry and immunohistochemistry using monoclonal antibodies specific for B and T lymphocyte subsets. Lymphocytes were compartmentalized into B (T-independent) and T-dependent …

A study of several factors incident to the absorption of choline from the small intestine of the albino rat
… to the mechanism by which it is absorbed by the intestinal mucosa.</p><p>The studies referred to thus far leave the field open for additional investigation. No mention was found in the literature of studies on selective areas of absorption of choline in the small intestine, or whether enzyme …

The hormonal mechanism of intestinal adaptation
The gastrointestinal tract has a large functional reserve. This is particularly true of the small intestine, and early studies by Flint in 1912, showed that dogs could withstand 50%-70% small intestinal resection, returning to normal health after an initial period of weight loss and malabsorption. …

Microcapsule Containing Lactic Acid Bacteria for Treatment of Peptic Ulcers
… the microorganisms that normally occur in the intestinal tract (Tannock, 1997). It has also been suggested that probiotics can prevent pathogen infections by adhering to the intestinal mucosa (Lee, Lim, Teng, Ouwehand, Tuomola, & Salminen, 2000). While probiotics can be delivered to the …

Recombinant Lactobacillus as a Vaccine Vector for HIV
… a well characterized commensal of the human intestinal tract, was engineered to express HIV antigens. In this study we have genetically cloned the HIV gag gene into Lactobacillus gasseri, confirmed the expression of Gag protein and evaluated the immunogenicity of the recombinant bacteria in a …

Mechanisms of Prostaglandin-Stimulated Recovery of Mucosal Barrier Function in the Ischemia-Injured Porcine Intestine: Role of Intestinal Ion Transport
… conducted to determine physiologic mechanisms of mucosal repair in the ischemia-injured intestine. The first experiment (Chapter III) investigated the contributory role of individual Cl- channels in the recovery of barrier function in ischemia-injured porcine ileum. Ischemia-injured porcine ileal …

Detection of colorectal carcinoma-associated antigens using specific antibodies against human milk oligosaccharides

Unravelling the role of microbiome and Escherichia coli as a trigger for Inflammatory Bowel Disease with a particular focus on Crohn's disease.
… precisely known. However, an imbalance in the intestinal microbiome (dysbiosis) and putative pathogens have been implicated. Several lines of evidence implicate bacteria in the pathogenesis of IBD, and Escherichia coli (E. coli) is one of the leading candidate triggers. These studies aimed to …

Oral uptake and distribution of microspheres
… experimental evidence suggesting that the gastrointestinal tract (GIT) may be penetrated by sub-micron sized polymeric particles which have the capacity to deliver therapeutic compounds. We investigated this, initially with Fluoresbrite™ carboxylate latex microspheres (0.87 m diameter) which were …
