Intraepithelial Lymphocytes: Scratching the surface

The epithelial surface is the site at which we first encounter pathogens. Two recent advances indicate that intraepithelial lymphocytes use specialized tools to help protect this surface.

Cell Density Counts of the Intestinal Intraepithelial Lymphocytes in the Celiac Patients

Background: Increased number of intestinal intraepithelial lymphocytes (IELs) is a key histological finding in the diagnosis of celiac disease (CD); however, the number of IELs in celiac patients and healthy subjects may vary from one region to another. Additionally, there are some seronegative celiac patients with a borderline histology. Objective: To determin...

Quantitation of intraepithelial lymphocytes in human jejunum.

An estimate of the number of intraepithelial lymphocytes in jejunal villous epithelium can be obtained by differential counting of nuclei in the epithelium. From counts carried out in 160 jejunal biopsies from patients who did not have coeliac disease the normal range has been established as 6-40 intraepithelial lymphocytes per 100 villous epithelial cells. In some biopsies there was a moderate...

The normal range of duodenal intraepithelial lymphocytes.

BACKGROUND Increased duodenal intraepithelial lymphocytes is a key histological finding in celiac disease. Available studies suggest a wide normal range (10 - 40 intraepithelial lymphocytes /100 epithelial cells, EC). We assessed the normal range of distal duodenal intraepithelial lymphocytes. METHODS Biopsies from the normal-looking distal duodenum from individuals referring for endoscopy fo...
