An investigation was undertaken to determine whether a recombinant gp160 envelope protein, which is currently being evaluated as a vaccine for AIDS, induces or modulates the production of tumour necrosis factor-alpha (TNF-alpha) or interleukin-1 beta (IL-1 beta). Incubation of monocytes from healthy, HIV-seronegative persons with 0.0001-1.0 micrograms of the recombinant vaccine did not result in the secretion of TNF-alpha or IL-1 beta, nor did the recombinant product augment or suppress monokine production by lipopolysaccharide (LPS) stimulated monocytes. The vaccine was also without a stimulatory or modulatory effect upon TNF-alpha or IL-1 beta secretion by monocytes from a patient with the AIDS-related complex (ARC) and from the monocytic THP-1 cell line. The lack of effect of gp160 on monokine production has important implications for its efficacy as a vaccine for AIDS.
开展了一项调查,以确定一种重组gp160包膜蛋白(目前正作为艾滋病疫苗进行评估)是否诱导或调节肿瘤坏死因子-α(TNF-α)或白细胞介素-1β(IL-1β)的产生。将健康的HIV血清阴性者的单核细胞与0.0001 - 1.0微克重组疫苗一起孵育,并未导致TNF-α或IL-1β的分泌,该重组产品也未增强或抑制脂多糖(LPS)刺激的单核细胞产生单核因子。该疫苗对艾滋病相关综合征(ARC)患者的单核细胞以及单核细胞THP-1细胞系分泌TNF-α或IL-1β也没有刺激或调节作用。gp160对单核因子产生缺乏影响对其作为艾滋病疫苗的疗效具有重要意义。
