A study in this issue of the JCI shows that in response to autoantigens consisting of peptides from normal proteins, patients with diabetes mount a T cell response characterized by production of IFN-gamma (see the related article beginning on page 451). However, in response to these same antigens, T cells from normal control subjects produce IL-10. The antigen-specific response characterized by release of a regulatory cytokine suggests a mechanism for the control of autoimmunity that is initiated at the time of antigen presentation.
本期《临床研究杂志》中的一项研究表明,针对由正常蛋白质肽段组成的自身抗原,糖尿病患者会产生以干扰素-γ分泌为特征的T细胞应答(见第451页开始的相关文章)。然而,针对相同抗原,正常对照受试者的T细胞产生白细胞介素-10。以调节性细胞因子释放为特征的抗原特异性应答提示了一种在抗原呈递时启动的自身免疫控制机制。
