title: Morphometric electron and light microscope analysis of lymphoid cells in coeliac disease.
abstract: Lymphocytes in jejunal biopsies from normal subjects and from untreated, treated, and gluten-challenged coeliac patients were examined by accurate morphometric methods. There was no significant difference between lymphocytes from different sources and those in the jejunum. Transforming lymphocytes were ultrastructurally quite different from non-transforming lymphocytes. The appearance of transforming lymphocytes in the lamina propria in different groups of coeliac patients is in accordance with the increase in the number of plasma cells. In treated patients the results indicate a rapid humoral response to gluten challenge.
