摘要
JM 是来自人胸腺不成熟 T 细胞的急性淋巴细胞白血病细胞系.本文以 SAC 刺激的人外周血纯化 B 淋巴细胞和小鼠脾细胞增殖为模型,观察了 JM 细胞培养上清(SPN_(JM))对人 B 淋巴细胞和小鼠脾细胞增殖的免疫调节作用.发现具有 T 细胞抑制活性的 SPN_(JM)对人和小鼠 B 淋巴细胞的增殖具有促进作用。在无 SAC 诱导时,SPN_(JM)与 HrIL—2协同对 B 细胞仍有促增殖作用.本实验还发现,高浓度时对 T 细胞具有抑制作用的 SPN_(JM),在低浓度时(1:640)对 T 细胞增殖亦具有促进作用.
JM is a acute lymphocytic leukemia cell line derived from immature T lymphocytes in human thymus.We bserved the immunoregulation effect of supernatants from JM cell culture(SPN_(JM))onproliferation of human B ymphocytes and mouse spleen cells by using purified human B lymphocytesand mouse spleen cells stimulated with AC.It is showed that SPN_(JM),which suppresses T lymphocyteproliferation,enhance the proliferation response of uman B cell and mouse spleen cells stimulatedwith SAC.Without inducement of SAC,SPN_(JM) with HrIL-2 still nhances B lympohocyteproliferation.Additionally,SPN_(JM) is able to up regulate T cell proliferation response at lowconcentration(1:640)although it suppresses T cell proliferation at high concentration.
