Neuroimmunomodulation in the Intestinal Mucosa

Gastroenterology Clinics of North America, 1991
The intestine contains major subdivisions of the nervous and immune systems. The lymphoid compartments of the intestine contain functionally distinguishable populations of immunologic cells and are innervated differently. The lamina propria has an extensive network of nerves using the neuropeptides SOM, SP, and VIP.

Neurobiology of the intestinal mucosa

Gastroenterology, 1986
The importance of the enteric nervous system for coordinating and programming the digestive modes of the gastrointestinal effecters is well recognized. Attention has been focused in the past on the involvement of intrinsic nerves in generating specific motility patterns of the smooth muscle effecters, with little regard for the influence of intrinsic ...

To Make a New Intestinal Mucosa

Rejuvenation Research, 2006
A number of clinical conditions are caused by disorders affecting the mucosal lining of the gastrointestinal tract. Some patients suffer from a loss of mucosal surface area due to congenital defects or due to surgical resections ("short bowel syndrome").

Adenosine is a vasodilator in the intestinal mucosa

American Journal of Physiology-Gastrointestinal and Liver Physiology, 1991
The vasoactivity of adenosine in the intestinal mucosa of anesthetized dogs was determined using two experimental techniques. By use of the microsphere technique, infusion of adenosine (1 mumol/min ia) was found to increase significantly venous outflow and mucosal and muscularis blood flows in both jejunum (+77, +72, and +78%) and ileum (+111, +146 ...

Morphology of the Intestinal Mucosa

1984
The three anatomic divisions of the small intestine are the duodenum, the jejunum, and the ileum. These total about 6 m in length in the human. The intestine receives the gastric chyme, which mixes with the secretions of Brunner’s glands, the crypts of Lieberkuhn, the liver, and the pancreas.

Serotonergic Integration In the Intestinal Mucosa

Current Pharmaceutical Design, 2020
Mucosal serotonin (5-HT) is a key paracrine signaling molecule in the integrated physiology of enterochromaffin cells, enteric mast cells, spinal afferent nerves and the enteric nervous system (ENS). Enterochromaffin cells release 5-HT as a paracrine signal to enteric mast cells, spinal afferents and neurons in the ENS.

Polyamine Distribution in the Rat Intestinal Mucosa [PDF]

Clinical Science, 1984
As the first step in a study of mucosal polyamine metabolism during intestinal adaptation, we have measured mucosal polyamine concentrations at different sites along the normal rat intestine. Putrescine, spermidine, spermine and cadaverine were measured by spectrofluorometric analysis after thin-layer chromatography of their dansylated derivatives ...

The ketokinase activity of the intestinal mucosa

Biochimica et Biophysica Acta, 1960
Abstract The ketokinase activity of homogenates of intestinal mucosa has been found to involve two enzymes, a heat-stable ketokinase which has a high affinity for fructose and sorbose and a heat-labile ketokinase which shows low affinity for both ketoses. The ketoses appear to be phosphorylated by both enzymes in the 1 position.

The Uptake of Lipids into the Intestinal Mucosa

1978
Fats, proteins, and complex carbohydrates represent the major sources of calories in the typical diet found in the Western world. During digestion within the proximal small intestine proteins and carbohydrates are broken down into simpler peptides and saccharides that are very polar and so are soluble in the aqueous environment of the intestinal ...

Lymphocytes of the intestinal mucosa of chickens

Cell and Tissue Research, 1988
Examination, by light and electron microscopy, of the morphology and the staining properties of intraepithelial lymphocytes from the intestine of the chicken revealed a population of lymphoid cells, of which a proportion (up to 20%) is granulated. The majority of cells were immunoreactive with anti-T cell serum and can therefore be considered to be ...
