Abstract

Adult T cell leukemia (ATL) is a malignant disease characterized by tumorous proliferation of CD4+ T cells infected with retrovirus human T cell leukemia virus Type-I (HTLV-I) and concurs with an autoimmune disease and cancer due to attenuated immune response. In this study, we established ATL patient derived B-cell line TM-1 producing cancer-specific IgM antibodies, and further characterized its antigen specificity by establishing hybridomas fused with human-mouse origin hetero-myeloma cell line RF-S1. We established three hybridoma cell lines termed 2E12, 3E9, and 3E10, which continuously secreted human IgM antibodies. Immunohistochemical staining of formalin-fixed tissue section using antibodies secreted from these hybridomas showed that these antibodies specifically recognized tumor sites of human colon adenocarcinomas. Antibody produced from hybridoma 3E9 bound to some of leukemic cell lines, but not to normal human PBL, which was evidenced by the flow cytometric analysis, indicating that antibody produced from 3E9 recognizes cell surface antigen specifically expressed in the leukemic cells.
