Sumario:Human dialysable Transfer Factor (TFd) extracted from lymphocytes of patients with transitional cell carcinoma of bladder (TCCB) was replicated in culture by lymphoblastoid cell lines. The effectiveness of two such TFdLs produced in vitro in transferring sensitivity to TCCB was assessed in the lymphocyte migration test (LMT) using formalin-treated TCCB cells as antigen. The results, showed that one TFdL transferred sensitivity in 5/14 cases and the other in 12/15, not only to leucocytes of healthy individuals but also to leucocytes of TCCB patients. Preliminary results showing an in vivo transfer of sensitivity are discussed.
