Abstract

Human lymphocytes were treated with human alpha (IFN-alpha), beta (IFN-beta), or recombinant gamma (IFN-gamma) interferons separately or in combination to determine their ability to enhance natural killing against mouse L cell targets. Our results showed that recombinant IFN-gamma was approximately 50 times more active per unit of antiviral activity than either IFN-alpha or IFN-beta. Moreover, the levels of natural killing by lymphocytes treated with combinations of IFN-alpha and IFN-beta were additive, whereas combinations of recombinant IFN-gamma and IFN-alpha or recombinant IFN-gamma and IFN-beta were synergistic. The development of natural killing in lymphocytes treated with recombinant IFN-gamma did not occur more rapidly but reached higher levels (62%) than that observed with lymphocytes treated with IFN-alpha or IFN-beta (15%). The results suggest the importance of IFN-gamma and mixtures of IFN-gamma with IFN-alpha or IFN-beta in the enhancement of natural killing activity against virus infections and neoplasia.

摘要

将人淋巴细胞分别或联合用人α干扰素(IFN-α)、β干扰素(IFN-β)或重组γ干扰素(IFN-γ)进行处理,以确定它们增强对小鼠L细胞靶标的自然杀伤能力。我们的结果显示,每单位抗病毒活性,重组IFN-γ的活性比IFN-α或IFN-β高约50倍。此外,用IFN-α和IFN-β联合处理的淋巴细胞的自然杀伤水平是相加的,而重组IFN-γ与IFN-α或重组IFN-γ与IFN-β的联合处理则具有协同作用。用重组IFN-γ处理的淋巴细胞中自然杀伤的发展速度并不更快,但比用IFN-α或IFN-β处理的淋巴细胞(15%)达到更高水平(62%)。结果表明IFN-γ以及IFN-γ与IFN-α或IFN-β的混合物在增强针对病毒感染和肿瘤的自然杀伤活性方面的重要性。
