Abstract

Monoclonal antibodies anti-T6 and anti-M241 define unique cell populations within different lineages: cortical thymocytes and dendritic cells in the skin. T6 positive cutaneous dendritic cells are located predominantly in the epidermis and belong to the Langerhans/indeterminate lineage, whereas, most of the M241 positive cells are located in the perivascular regions of the dermis. Biochemical analysis of thymocytes and cutaneous dendritic cells was performed in order to determine whether the reactivity of these antibodies with these cell types is due to sharing of antigenic determinants by two unrelated proteins, or whether similar proteins are present on cells of different lineages. Our results indicate that T6 antigens are borne by the same glycoprotein (49K) on cortical thymocytes and Langerhans/indeterminate cells. Similarly, M241 antigens isolated from thymocytes and cutaneous dendritic cells are found on the same glycoprotein (43K).
