目的探討預(yù)輸注5-FU處理過的同種異基因淋巴細(xì)胞對(duì)大鼠移植肝的影響。方法實(shí)驗(yàn)分4組,均行Wistar大鼠至SD大鼠的肝移植。 對(duì)照組: 僅行肝移植; 單純淋巴細(xì)胞組: 受體于術(shù)前第7天及第4天各輸注Wistar大鼠淋巴細(xì)胞(5×10 6個(gè)/ml)懸液1 ml; 低濃度5-FU預(yù)處理組: 受體于術(shù)前第7天及第4天各輸注經(jīng)7.5 μg 5-FU處理過的Wistar大鼠淋巴細(xì)胞(5×10 6個(gè)/ml)懸液1 ml; 高濃度5-FU預(yù)處理組: 受體于術(shù)前第7天及第4天各輸注經(jīng)15 μg 5-FU處理過的Wistar大鼠淋巴細(xì)胞(5×10 6個(gè)/ml)懸液1 ml。于術(shù)后第7天處死SD大鼠,行移植肝臟Fas-L及CD8免疫組化檢測(cè)。結(jié)果肝小葉及匯管區(qū)中,低濃度5-FU預(yù)處理組Fas-L表達(dá)陽性細(xì)胞的IOD均高于對(duì)照組、單純淋巴細(xì)胞組和高濃度5-FU預(yù)處理組(P lt;0.05); 單純淋巴細(xì)胞組與高濃度5-FU預(yù)處理組比較差異無統(tǒng)計(jì)學(xué)意義(P gt;0.05)。肝小葉中, CD8+ T淋巴細(xì)胞的IOD在單純淋巴細(xì)胞組、低濃度5-FU預(yù)處理組和高濃度5-FU預(yù)處理組的差異無統(tǒng)計(jì)學(xué)意義(P gt;0.05); 在匯管區(qū),低濃度5-FU預(yù)處理組的CD8+ T淋巴細(xì)胞IOD低于單純淋巴細(xì)胞組、高濃度5-FU預(yù)處理組和對(duì)照組(P lt;0.05)。結(jié)論預(yù)輸注經(jīng)低濃度5-FU處理的同種異基因淋巴細(xì)胞可以較好地誘導(dǎo)大鼠肝移植免疫耐受,其可能的機(jī)理是通過誘導(dǎo)移植物中Fas-L表達(dá)的上調(diào),從而獲得免疫耐受。
