Abstract
目的 探讨小分子化合物J2对异基因角膜移植小鼠淋巴细胞的影响.方法 建立小鼠角膜移植模型,随机分为A、B、C、D 4个组.A组为空白对照组3只BALB/c小鼠,B、C、D组各11只鼠,均取右眼行C57BL/6-BALB/c同种异体角膜移植术,自手术当日开始腹腔注射给药,B组给予不含药物的安慰剂,C组给予环孢素A(CsA)10mg/kg,D组给予J2 15mg/kg,每日1次,连续给药12d.给药后7d,取大鼠脾细胞给予刀豆蛋白(ConA)刺激细胞增生,采用ELISA法测定细胞上清液中白细胞介素-2(IL-2)及IL-4的含量,比较各组细胞增生指数及细胞因子含量.结果 B组角膜植片平均存活时间为(18.88±4.19)d,C组、D组发生排斥时间分别为(35.13±5.74)d、(33.62±6.80)d,明显延迟,与B组比较差异均有统计学意义(q=9.17,P＜0.01;q=8.33,P=0.00),而C组与D组比较差异无统计学意义(q=0.85,P=0.60).ConA刺激角膜移植后小鼠脾细胞增生,各组小鼠脾细胞的增生指数差异无统计学意义(F=3.729,P=0.061).异基因小鼠角膜移植后3周左右小鼠脾细胞中IL-2和IL-4的含量无明显变化.应用ConA刺激后ELISA法检测结果表明,角膜移植小鼠脾细胞分泌IL-2明显增多,J2可抑制ConA诱导的IL-2分泌增加.结论 J2可能通过抑制CD4+ T淋巴细胞而抑制角膜排斥反应的发生;J2能够明显抑制ConA刺激角膜移植后小鼠脾细胞的增生及Th1细胞因子的产生。
