T(H)-17 cells have been shown to play a role in bacterial defense, acute inflammation, and autoimmunity. We examined the role of interleukin 17 (IL-17) production in human immunodeficiency virus type 1 (HIV-1) infection. Both HIV-1- and cytomegalovirus (CMV)-specific IL-17-producing CD4(+) T cells were detectable in early HIV-1 infection but were reduced to nondetectable levels in chronic and nonprogressive HIV-1 infection. IL-17-producing CMV-specific cells were not detected in blood from HIV-1-uninfected normal volunteers. Virus-specific T(H)-17 cells could coexpress other cytokines and could express CCR4 or CXCR3. Although the etiology of these cells has yet to be established, we propose that microbial translocation may induce them.
辅助性T细胞17(T(H)-17细胞)已被证明在细菌防御、急性炎症和自身免疫中发挥作用。我们研究了白细胞介素17(IL-17)产生在1型人类免疫缺陷病毒(HIV-1)感染中的作用。在HIV-1感染早期可检测到HIV-1特异性和巨细胞病毒(CMV)特异性产生IL-17的CD4(+) T细胞,但在慢性和非进展性HIV-1感染中减少到检测不到的水平。在未感染HIV-1的正常志愿者血液中未检测到产生IL-17的CMV特异性细胞。病毒特异性T(H)-17细胞可共表达其他细胞因子,并可表达CCR4或CXCR3。尽管这些细胞的病因尚未明确,但我们认为微生物易位可能会诱导它们产生。
