| 摘 要： | 目的：检测一种恶性疟原虫保护性抗原重组复合基因表达产物（ＨＲＡ）诱导小鼠细胞免疫的反应．方法：免疫小鼠的脾淋巴细胞，体外分别经ＣｏｎＡ、ＨＲＡ和可溶性裂殖子抗原（ＳＭＡ）的刺激，３Ｈ－ＴｄＲ参入法检测淋巴细胞的增殖水平．结果：含佐剂的ＨＲＡ免疫ＢＡＬＢ／ｃ和Ｃ５７ＢＬ／６小鼠后，其脾细胞经ＨＲＡ刺激后，增殖明显，可溶性裂殖子抗原免疫的ＢＡＬＢ／ｃ小鼠脾细胞经ＨＲＡ刺激发生明显的增殖．结论：ＨＲＡ上的Ｔ细胞位点发挥了效应．具有一定的突破ＭＨＣ限制的能力．

| Abstract: | Objective: The cellular immune responses to a Plasmodium falciparum hybrid recombinant antigen (HRA) were investigated. HRA codes for several T/B cell epitopes from MSA1, MSA2, RESA and Universal T cell epitopes of IL 1, tetanus toxiod. Methods: Splenocyte proliferation of immunized mice was examined by 3H TdR incorporation. Results: HRA could prominently induce splenocyte proliferation of BALB/c and C57BL/6 mice after immunized with HRA emulsified with Freund adjuvant.HRA could also induce prominently proliferation BALB/c mice immunized with soluble merozoite antigen (SMA). Conclusion: T cell epitopes of HRA are effective. HRA may overcome MHC restriction. |
