The light and dark sides of intestinal intraepithelial lymphocytes

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...

Intestinal intraepithelial lymphocytes: the plot thickens

O ver the last few years, the characterization of T lyraphocytes within the intestinal epithelium (ilEL) has revealed phenotypic and functional heterogeneity that rivals only that observed within the thymus. Of note in this context is that thymic and intestinal epithdia share the same embryologic origin in that they are both derived from endoderm. Several lines of evidence have led to the concl...

Self-verification 3608: Illuminating the Light and Dark Sides

Self-verification theory assumes that people actively work to preserve their selfviews, even if these self-views are negative. This article considers the benefits and drawbacks of receiving self-verification. Direct benefits of self-verification include psychological coherence, reduced anxiety, and improved health. Indirect benefits include greater intimacy and trust in relationships and more h...

Small Intestinal Intraepithelial Lymphocytes Maximum Immunobioactivity of Murine

Migration of intestinal intraepithelial lymphocytes into a polarized epithelial monolayer.

Intraepithelial lymphocytes (IEL) are a phenotypically distinct population of lymphocytes that reside in mucosal epithelia, below the intercellular tight junctions. Although adhesive functions of this population have been previously studied, relatively little is known about IEL migration from the microvasculature into the epithelium. We demonstrated that cultured human IEL were capable of migra...
