目的:体内预存的各种记忆细胞是器官移植中的重要障碍。记忆细胞对侵入的病原体产生强烈的免疫反应,但同时会导致移植物发生排斥。研究发现,沙利度胺在初次器官移植中具有抑制免疫排斥反应的作用,但其作用机制仍不明确。沙利度胺在器官移植中的潜在作用,很有可能使其成为作用于新靶点、高效低毒的免疫抑制剂。这里,我们拟研究沙利度胺联合共刺激分子阻断剂对皮肤预致敏小鼠心脏移植物生存期的作用,并探讨其在免疫记忆中的作用机制。 方法:首先通过同种异体皮肤移植得到预致敏小鼠,然后随机将皮肤预致敏小鼠分成4组,每组6只。对照组(control组,Ctrl)给予同型抗体,共刺激分子阻断剂组(Ab组)在心脏移植第0、2、4...Background: Before organ transplantation, various memory cell populations existing in transplantation are known to be key barriers. They may fight against the effects of immunosuppressive therapies which were used to prolong graft survival, although memory cells usually could express robust immune responses when meeting invading pathogens. Therefore, the development of new targets, efficiency and ...学位:医学硕士院系专业:医学院_外科学学号:2452012115319
