接触性超敏反应(CHS)需要T细胞以及多种细胞因子和粘附分子的参与。在经典的CHS中,抗原特异性T细胞被招募到抗原攻击部位,在那里它们与抗原反应,释放细胞因子,并吸引其他炎症细胞。在小鼠CHS模型中,致敏小鼠在免疫后4-7 d应用免疫原可引起该反应。反应在24小时达到高峰,48小时后略有减少,72小时后可恢复正常。尽管某些抗原仍然存在于攻击部位。在这里,我们检验了局部产生的白细胞介素10 (IL-10)调节反应持续时间的假设。我们的数据显示,IL-10蛋白在抗原激发后10-14小时达到峰值,并在24小时后返回背景。通过逆转录-聚合酶链反应检测,IL-10蛋白的产生与IL-10 mRNA的转录相对应,并遵循其转录。在抗原攻击后IL-10产生高峰期,除非先给予IL-10的中和抗体,否则不可能用免疫淋巴样细胞转移CHS。此外,当致敏小鼠在抗原刺激时给予中和的抗IL-10抗体时,CHS的持续时间远远超过自然反应的过程。最后,我们证明,在抗原性攻击之前将rIL-10注射到皮肤中,可以阻止先前致敏的小鼠产生CHS。综上所述,我们的数据显示IL- 10在体内CHS反应的自然调节中发挥了重要作用。
Contact hypersensitivity (CHS) responses require the participation of T cells, along with a variety of cytokines and adhesion molecules. In the classical CHS, antigen-specific T cells are recruited to a site of antigenic challenge, where they react with antigen, release cytokines, and attract other inflammatory cells. In the mouse model of CHS, this reaction is elicited in sensitized mice by application of the immunogen 4-7 d after immunization. The reaction peaks at 24 h, is slightly reduced by 48 h, and can return to normal by 72 h. This is in spite of the fact that some antigen is still present at the site of challenge. Here we examined the hypothesis that locally produced interleukin 10 (IL-10) regulates the duration of the response. Our data show that IL- 10 protein peaked 10-14 h after antigenic challenge and returned to background by 24 h. The production of IL-10 protein corresponded with, and followed IL-10 mRNA transcription as detected by reverse transcriptase-polymerase chain reaction. During peak IL-10 production after antigenic challenge, it was not possible to transfer CHS with immune lymphoid cells, unless neutralizing antibody to IL-10 was given first. Additionally, when sensitized mice were given neutralizing anti- IL-10 antibody at the time of antigenic challenge, the duration of CHS was prolonged well beyond the natural course of the response. Finally, we demonstrate that rIL-10, when injected into the skin before antigenic challenge, prevented the elicitation of CHS in previously sensitized mice. Taken together, our data show an important role for IL- 10 in the natural regulation of CHS responses in vivo.
