the results indicate that the 7f7 antigen and the p3.58 melanoma antigen are identical , that some epitopes of this adherence molecule are differentially expressed on individual cell types and that one epitope , which is only weakly expressed on activated t cells , does not contribute to the role of the 7f7 antigen in some examples of cell-cell adherence .
