Abstract

AIM

To evaluate the effects of ribavirin on cytokine production of recall antigen and PHA-stimulated PBMC obtained from healthy individuals.

MATERIALS AND METHODS

PBMC were challenged with tetanus toxoid (5 microg/mL) and PHA (10 microg/mL) in absence or presence of ribavirin at different concentrations (1, 10 and 100 (microM). Parallel sets of wells containing PBMC exposed to medium alone were used as negative controls. On day 3 after initiation of the cultures, IL-2, IFN-gamma, IL-4, IL-10, TNF-alpha content were determined in supernatants of PBMC from the different individuals.

RESULTS

The effects of ribavirin on cytokine released by human PBMC in response to PHA and TT showed a great variation among individuals. No significant changes were observed between 1-10 microM concentrations in the production of TNF-alpha, IFN-gamma and IL-10 by both PHA and TT-stimulated PBMC. Ribavirin inhibited TNF-alpha, IFN-gamma, and IL-10 in both PHA and TT-stimulated PBMC at 100 microM (p <0.05). At this concentration, ribavirin induced an increase of 124% in the production of IL-2 by PHA-stimulated PBMC (p <0.05).

CONCLUSIONS

The present data suggest that ribavirin may cause diverse effects on immunoregulatory cytokine secretion with changes in the Th1/Th2 balance.

摘要

目的

评估利巴韦林对从健康个体获得的回忆抗原和PHA刺激的外周血单个核细胞(PBMC)细胞因子产生的影响。

材料与方法

在不存在或存在不同浓度(1、10和100μM)利巴韦林的情况下,用破伤风类毒素(5μg/mL)和PHA(10μg/mL)刺激PBMC。将含有仅暴露于培养基的PBMC的平行孔板用作阴性对照。在培养开始后的第3天,测定来自不同个体的PBMC上清液中的IL-2、IFN-γ、IL-4、IL-10、TNF-α含量。

结果

利巴韦林对人PBMC响应PHA和破伤风类毒素释放的细胞因子的影响在个体间存在很大差异。在1-10μM浓度之间,PHA和破伤风类毒素刺激的PBMC产生的TNF-α、IFN-γ和IL-10没有观察到显著变化。在100μM时,利巴韦林抑制PHA和破伤风类毒素刺激的PBMC中的TNF-α、IFN-γ和IL-10(p<0.05)。在此浓度下,利巴韦林使PHA刺激的PBMC中IL-2的产生增加了124%(p<0.05)。

结论

目前的数据表明,利巴韦林可能对免疫调节细胞因子的分泌产生不同影响,并改变Th1/Th2平衡。
