Bonavida B
J Immunol. 1977 Oct;119(4):1530-3.
Mice sensitized against a tumor allograft and given cyclophosmamide 6 days later failed to generate an immune response to the allograft. Spleen cells derived from these mice suppressed the generation of cytotoxic T cell response by normal spleen cells in mixed leukocyte cultures. The suppressor cells were not specific, thymus dependent, and resistant to 2000 R.
对肿瘤同种异体移植物致敏的小鼠,6天后给予环磷酰胺,未能对同种异体移植物产生免疫反应。来自这些小鼠的脾细胞在混合白细胞培养物中抑制了正常脾细胞的细胞毒性T细胞反应的产生。抑制细胞是非特异性的,依赖胸腺,且对2000伦琴有抗性。
