CD103, also known as Integrin alpha E or ITGAE, is a membrane-associated protein that belongs to the family of integrins. It functions in cell adhesion, migration, cell signaling and localization of lymphocytes in epithelial tissues. CD103 is expressed on T-lymphocytes in gastro-intestinal tract, bronchoalveolar fluids and allograft tissues. Immune cells in spleen or peripheral lymph nodes poorly express CD103. Antibody CD103 may be helpful in detection of hairy cell leukemia and HCL variants, which are CD103 positive. Most other hematologic malignancies are negative for CD103.
