The question under analysis in this commentary is, what was the evolutionary selection pressure that necessitated the ectopic expression of a subset of peripheral self-antigens in the thymus and by peripheral APC? The suggestion is that antigen expression is delayed until after the immune system is responsive.
本评论分析的问题是,是什么进化选择压力需要在外周自身抗原的子集在胸腺和外周 APC 中异位表达?这表明抗原表达是延迟到免疫系统有反应之后。
