The internalization and intracellular processing of monoclonal antibody to immunoglobulin mu heavy chain (Mamu) have been investigated in two human Burkitt lymphoma cell lines (Ramos and Raji), in a human B cell lymphoma and in normal human peripheral blood B cells. In addition to the degradation of 125I-labeled Mamu to trichloroacetic acid (TCA) soluble material, a distinct pattern of larger 125I-Mamu fragments was detected in all sources of B cells tested. The particular fragmentation pattern, as revealed by sodium dodecyl sulfate-polyacrylamide gel electrophoretic analysis, involved the cleavage of both peptide bonds and disulfide bridges. This type of antibody fragmentation appeared to be a selective mechanism associated with sIgM, as no other degradation than that leading to TCA-soluble material could be detected after the internalization and degradation of radiolabeled monoclonal antibodies towards a variety of non-Ig B cell surface receptors. Three fragments of 125I-Mamu degradation were also detected in the supernatant of Ramos cells, implying that the recycling and exocytosis of certain 125I-Mamu fragments also took place.
