【摘要】目的探討干擾素（IFN）對人結腸癌細胞人類白細胞抗原DR(HLA-DR)表達的影響。
方法采用免疫組化SP法和ELISA法分別檢測不同劑量的α-IFN和γ-IFN刺激前、后HLA-DR在4株人結腸癌細胞HCT-8、Lovo、SW-480和Ls-174-T中的表達情況。
結果α-IFN和γ-IFN刺激之前，4株細胞中除Lovo細胞不表達HLA-DR，其他3株細胞均可不同程度表達HLA-DR; 刺激之后，4株細胞系的HLA-DR表達均有所增強，并呈現出IFN依賴性及γ-IFN的劑量依賴性，γ-IFN的誘導作用強于α-IFN。
結論IFN可以上調人結腸癌細胞HLA-DR的表達，IFN用于結腸癌的臨床治療具有一定的應用前景。
