Abstract

Preincubation of peripheral blood non-adherent mononuclear cells with purified or recombinant interleukin 2 (IL-2) significantly enhanced natural killer (NK) activity against uninfected and varicella-zoster virus (VZV)-infected targets, while antibody-dependent cellular cytotoxicity (ADCC) against VZV-infected targets was not increased. Preincubation of effector cells with IL-2 had no effect on conjugate formation, but lysis of both targets was increased in single cell assays. IL-2-enhanced NK against VZV-infected targets was independent of gamma-interferon (gamma-IFN) production.

摘要

用纯化的或重组白细胞介素2(IL-2)对人外周血非贴壁单核细胞进行预孵育,可显著增强其对未感染和水痘-带状疱疹病毒(VZV)感染靶细胞的自然杀伤(NK)活性,而对VZV感染靶细胞的抗体依赖性细胞毒性(ADCC)并未增加。用IL-2对效应细胞进行预孵育对细胞结合形成没有影响,但在单细胞试验中,两种靶细胞的裂解均增加。IL-2增强的针对VZV感染靶细胞的NK活性与γ干扰素(γ-IFN)的产生无关。
