摘要:: Natural cytotoxicity against bovine leukemia cells (PC-3 cells) was found in bovine peripheral blood lymphocytes (PBL), and in non-adherent cells but not in adherent cells to nylon-wool column. Natural cytotoxic cells (NCC), which have natural cytotoxic activity, are found in T cell-rich fraction. When NCC were cocultured with PC-3 cells, natural cytotoxic factor (NCF) was released rapidly from NCC, and dose-response curve for NCF was almost linear induction. Cytotoxicity against PC-3 cells by NCC or NCF was increased with an increment of incubation period. Cytotoxicity against K562 cells, CL-1 cells, M1 cells or EL-4 cells by NCF was almost the same level as that against PC-3 cells, but that against those cell lines by NCC was not found. NCF activity in culture fluid from NCC cocultured with K562 cells or CL-1 cells was lower than that from NCC cocultured with PC-3 cells.
