Intra epitheliale lymfocytose
WebIntestinal intraepithelial lymphocytes (IEL) comprise distinct groups of innate-like and memory T cells that collectively form one of the largest T cell compartments in the body. IEL are located within the intestinal epithelium and are the first immune cells in the gut to interact with the food, microbiota, and pathogens that the gut is continually exposed to. WebBackground : A raised intraepithelial lymphocyte (IEL) count with normal villous architecture is a recognised finding in latent coeliac disease. Little information is available in cases without gluten sensitive enteropathy in adults. Aims: To assess the frequency of such a finding in routine practice and to determine whether it is clinically relevant.
