摘要
目的探索混合皮肤移植中，自体皮岛诱发移植免疫耐受的免疫机制。方法在体外建立混合表皮淋巴细胞(MELC)培养体系，以反映移植受者对皮肤移植物的免疫排斥反应。同时，将自体表皮细胞引入已建立的混合表皮淋巴细胞培养体系，以模仿混合皮肤移植中的自体皮岛效应,并分析发挥抑制效应的细胞来源。结果自体角质形成细胞可抑制淋巴细胞对同种异体抗原的增殖。结论自体皮岛中的角质形成细胞参与对同种异体抗原的提呈而诱导移植物耐受。
：Aim To explore the mechanism of the immune tolerance induced by the auto-islets in the intermingled skin grafting. Methods The mixed epidermal cell and lymphocyte culture (MELC) was established, in which auto-keratinocytes were added to mimic the effect exerted by the auto-islets in vivo. Results Auto-keratinocytes could inhibit the lympho-proliferation induced by alloantigen. Conclusion The immune tolerance induced by auto-islets may be related to the function of auto-keratinocytes as antigen presenting cells.
