It is now well established that interactions of CD40 on the B cells, along with its ligand (CD40-L) on the T cells, regulate B cell proliferation and differentiation. However, the functional significance of CD40 expression on cells known for most efficient Ag-presenting function, i.e., dendritic cells, is not so clear. In this study, we demonstrate that CD40 is expressed on human dendritic Langerhans cells (LC) freshly isolated from epidermis. Using CD40-L transfected cells, CD40 triggering was… CONTINUE READING
