intraepithelial lymphocyte

T cell memory and development of intraepithelial lymphocytes.

An accepted name for this type of pathology is needed, such as'high density intraepithelial lymphocyte enteropathy'.

Intraepithelial lymphocytes: distributed throughout the tissue.

Intraepithelial lymphocytes rarely expressd CD25, although when found this was more common in the crypt than surface epithelium.

An increased intraepithelial lymphocyte count should always suggest the possibility of gluten ingestion in treated patients, even when the mucosal structure looks otherwise normal.

Inflammatory cells are increased both in the surface epithelium ("intraepithelial lymphocytes") and in the lamina propria.

Local increase in the number of intraepithelial lymphocytes seems to be an early event in the coeliac lesion (the so called infiltrative lesion).

Intraepithelial lymphocytes were immunonegative for class II major histocompatibility complex, while epithelial cells showed increased expression of this product in coeliac disease.

One approach to the recognition of potential latent or low grade coeliacs is by studies of intraepithelial lymphocyte T cells expressing gamma/delta receptors.

Thus, all this study seems to tell us is that it is rather dangerous to evaluate rectal intraepithelial lymphocytes in terms of enterocyte nuclei (Fig 4).

The study however did find an increase number of patients with higher intraepithelial lymphocytes (IEL, a type of white bloodcell) in the oat-eating cohort.

This study confirms previous results indicating the intraepithelial lymphocyte count is the most sensitive morphometric parameter of gluten induced mucosal changes in coeliac disease patients.

A definite increase in the intraepithelial lymphocyte count was indeed found at the end of the challenge in all subjects who had received 100 or 500 mg/day of gliadin.

Intraepithelial lymphocytes (lELs), and poly-morphonuclear leukocytes (PMNs), which reside in the epithelial mucosa, are recruited to damaged regions.

The following morphometric parameters were evaluated: villous height, crypt depth, villous height/crypt depth ratio, and the intraepithelial lymphocyte count.

There is now a substantial body of evidence that the expression of gluten hypersensitivity as enteropathy may be minimal, measurable only if a count of intraepithelial lymphocytes is performed.

Anti-gliadin and reticulin antibodies as well as numbers of intraepithelial lymphocytes (IELs) did not differ significantly between oat-eating celiacs and non-oat eating controls in remission.

The numbers of intraepithelial lymphocytes for a total of 1000 enterocytes was counted and expressed as intraepithelial lymphocytes per 100 enterocytes, as previously described.

Five or fewer intraepithelial lymphocytes per 100 epithelial cells in surface and crypt lining were considered to be within normal limits (Table 2, G and H) [ 21 ] .

Apart from our own prospective studies there seems to have been only one other approach to rectal mucosa in gluten sensitivity based on a retrospective analysis of intraepithelial lymphocytes material obtained 25 years previously.

Consequences of the stimulation of the intraepithelial lymphocyte could be cytokine induced crypt hyperplasia, increased epithelial HLA class II expression, and increased epithelial permeability.

Intraepithelial lymphocytes (IEL) are lymphocytes found in the epithelial layer of mammalian mucosal linings, such as the gastrointestinal (GI) tract and reproductive tract.

Some characteristics of this underdeveloping sparse mucosal immune system is a lamina propriar that does not have IgA plasma cells or CD4 cells, and very little amounts of intraepithelial lymphocytes.

Studies of jejunal fluid revealed the coeliac like intestinal antibody pattern in 16 of 98 non-coeliac cases, of whom six also had a high count of intraepithelial lymphocytes (Arranz and Ferguson, submitted).
