大量实验显示γ 干扰素 (IFN γ)在固有性抗肿瘤免疫和适应性抗肿瘤免疫中发挥重要作。有关IFN γ在肿瘤免疫中的效应机制已有很多解释 ,但有关早期干扰素的来源尚不清楚。众所周知γδT细胞在病原微生物入侵早期的防御性免疫反应中起关键作用 ,且可产生大量的γ 干扰素 ,因而 Numerous experiments have shown that interferon gamma (IFN gamma) plays an important role in intrinsic antitumor immunity and adaptive antitumor immunity. There are many explanations for the mechanism of IFNγ’s effect on tumor immunity, but the sources of early interferons are unclear. It is well-known that γδ T cells play a key role in the defensive immune response early in the invasion of pathogenic microorganisms and can produce large amounts of interferon-γ, thus
