Abstract

Interleukin 19 (IL-19) and interleukin 24 (IL-24) are cytokines that are highly expressed in filarial infections. To study the role of IL-19 and IL-24 in regulating T-cell responses, we examined the frequency of T-helper type 1 (Th1)/Tc1, Th2/Tc2, Th9/Tc9, Th17/Tc17, Th22/Tc22, and Tr1 cells in 26 filariae-infected individuals stimulated with filarial antigen following IL-19 or IL-24 neutralization. IL-19 or IL-24 neutralization resulted in significantly enhanced frequencies of Th1/Tc1 and/or Th17/Tc17 cells and significantly reduced frequencies of Th2/Tc2, Tr1, and/or Th9/Tc9 cells. Thus, we demonstrate that IL-19 and IL-24 are associated with the modulation of T-cell responses in filarial infections.

摘要

白细胞介素19(IL-19)和白细胞介素24(IL-24)是在丝虫感染中高表达的细胞因子。为了研究IL-19和IL-24在调节T细胞反应中的作用,我们检测了26名丝虫感染个体在IL-19或IL-24中和后用丝虫抗原刺激时,1型辅助性T细胞(Th1)/1型细胞毒性T细胞(Tc1)、2型辅助性T细胞(Th2)/2型细胞毒性T细胞(Tc2)、9型辅助性T细胞(Th9)/9型细胞毒性T细胞(Tc9)、17型辅助性T细胞(Th17)/17型细胞毒性T细胞(Tc17)、22型辅助性T细胞(Th22)/22型细胞毒性T细胞(Tc22)和1型调节性T细胞(Tr1)的频率。IL-19或IL-24中和导致Th1/Tc1和/或Th17/Tc17细胞频率显著增加,Th2/Tc2、Tr1和/或Th9/Tc9细胞频率显著降低。因此,我们证明IL-19和IL-24与丝虫感染中T细胞反应的调节有关。
