Reaction patterns of the 7th Human Leukocyte Differentiation Antigen Workshop blind panel adhesion molecules were studied on CD3/CD4, CD3/CD8, CD3/TCRγδ double positive T cells from peripheral blood of patients with chronic graft versus host disease (n=8) and healthy controls (n=4). Reactivity of 14 adhesion antibodies was tested by three-colour immunophenotyping. The mean proportion of CD3+ T cells (69±19%), CD3/CD8++ (31±13%) and CD3/TCRγδ++ (4±2%) T sub-populations of patients were comparable with the healthy controls. However, the mean percentage of CD3/CD4++ T cell subset in patients (14±12%) proved to be significantly decreased in comparison with the normal control value (34±16%) presumably due to secondary immunodeficiency. The workshop antibodies proved to be reactive with three T cell subsets expressing the examined antigens. Based on the results of the adhesion molecule workshop new CD categories have been introduced: CD156b as a transmembrane protein, CD167a as an epithelial tyrosin kinase receptor, CD168 as a receptor for hyaluronan mediated motility (RHAMM) and CD171 as a co-stimulatory adhesion molecule. There were significant differences in the expression of the CD167a and CD156b antigens on the CD3/CD4++ subset between the samples of patients compared with the controls characterizing the CD4+ T lymphocyte subpopulation in chronic graft versus host disease.
