Abstract: ミニブタの同種移植における免疫反応の指標を得る目的で, ドナー末梢血リンパ球(PBL)前処置した後, ドナーPBLに対する in vitroでのIL-2様活性の測定を行い, 以下の結果が得られた: (1)MHC不適合無処置群の48時間MLC上清中にIL-2様活性がみられ, 48時間培養の方が高値であった; (2)MHC不適合PBLを1回移植した群は, 無処置群よりも in vitroでのIL-2様活性は高値であった; (3)MHC不適合PBLを週1回計4回移植した群は, in vitroでのIL-2様活性の検出がやや早期に認められた. / In order to determine the means of monitoring the immunological status of allograft recipients in miniature swine, an assay was developed to measure interleukin (IL)-2 production in vitro by pretreatment of donor peripheral blood lymphocytes (PBL). Miniature swine were given 0 to 4 weekly intravenous transfusions of 5-10×10^7 donor PBL incompatible at major histocompatibility complex (MHC) and assayed in vitro for donor specific immune IL-2-like activities. The results are summarized as follows: (1) IL-2-like activity in 24 hr and 48 hr supernatants from mixed lymphocyte cultures (MLC) with MHC-incompatible PBL was detected without pretreatment. The 48 hr MLC supernatant exhibited a high IL-2-like activity compared with the 24 hr; (2) IL-2-like activity after only one transfusion with MHC-incompatible PBL was higher than that without pretreatment; (3) IL-2-like activity in 4 weekly transfusions was detectable slightly earlier than that without pretreatment or three transfusions with MHC-incompatibile PBL.
