ThIL-17 (IL-17+/IFN-gamma-) cell lines are significantly more encephalitogenic than Th1 (IL-17-/IFN-gamma+) cell lines in adoptive transfer EAE models. In actively induced EAE short ex vivo peptide stimulation identifies an IL-17+/IFN-gamma+ population of CD4+ CNS-infiltrating MOG35-55-specific T cells, which outnumber IL-17+/IFN-gamma- cells by approximately 3:1 as disease develops. A decrease in numbers of IL-17+/IFN-gamma+ cells following in vitro culture is accompanied by an increase in IL-17-/IFN-gamma+ cell numbers. Together these ex vivo and in vitro observations imply that the Th1 lineage is more encephalitogenic than is suggested by adoptive transfer of Th1 (IL-17-/IFN-gamma+) cell lines which have been terminally differentiated in vitro.
在过继转移实验性自身免疫性脑脊髓炎(EAE)模型中,Th17(IL-17+/IFN-γ-)细胞系比Th1(IL-17-/IFN-γ+)细胞系具有更强的致脑炎性。在主动诱导的EAE中,短时间的体外肽刺激可鉴定出一群IL-17+/IFN-γ+的CD4+中枢神经系统浸润性MOG35-55特异性T细胞,随着疾病发展,其数量比IL-17+/IFN-γ-细胞多出约3倍。体外培养后IL-17+/IFN-γ+细胞数量减少的同时,IL-17-/IFN-γ+细胞数量增加。这些体内外观察结果共同表明,Th1谱系的致脑炎性比体外终末分化的Th1(IL-17-/IFN-γ+)细胞系过继转移所显示的更强。
