当HIV-1感染细胞被某些抗原刺激激活时,细胞因子反应会受到极大的影响。我们报道了HIV-1Tat基因在T(Jurkat)和B(Raji)细胞系中对细胞因子调节的作用。研究TAT和/或PMA+PHA对14种细胞因子(IL-1α、IL-2、IL-4、IL-5、IL-6、IL-8、IL-10、IL-12、肿瘤坏死因子-α、肿瘤坏死因子-β、粒-巨噬细胞集落刺激因子、转化生长因子-β、干扰素-γ和巨噬细胞生长因子-1α)表达的影响。除了对细胞因子β的稳态水平有不同的影响外,TAT还可以像Raji B细胞那样单独或与Jurkat T细胞一样在PMA+PHA刺激下协同诱导B细胞和T细胞分泌肿瘤坏死因子-mRNAs。
Cytokine responses are dramatically affected when HIV-1 infected cells are activated with certain antigenic stimuli. We report the effects of HIV-1 tat gene in cytokine modulation, using HIV-1 tat transfected T (Jurkat) and B (Raji) cell lines. Studying the effect of tat and/or PMA+PHA on mRNA expression of 14 cytokines (IL-1α, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12, TNF-α, TNF-β, GM-CSF, TGF-β, IFN-γ and MIP-1α) illustrated differential effects. In addition to the varied effects of tat on the steady state levels of cytokine mRNAs, tat induced the secretion of TNF-β preferentially in both B and T cell lines, either by itself as in Raji B cell line or synergistically upon PMA+PHA stimulation as in Jurkat T cell line.
