分子免疫学家的梦想是阐明一个基本的生化过程,解释影响数百万人的疾病的根源,并且如果准确理解这一过程,可能会产生一种合理的诊断、预防或治疗方法。在本期 JBC 中,Ting 等人。报告了蛋白质组学、生化和结构分析,更好地解释了抗原呈递的 HLA-DR4 分子如何结合瓜氨酸肽以引发类风湿性关节炎 (RA),这是一种影响 0.5-1% 人口的慢性自身免疫性疾病。
The molecular immunologist's dream is to elucidate a fundamental biochemical process that explains the basis of an affliction that affects millions of people, and that, precisely understood, might yield a rational approach to diagnosis, prevention, or therapy. In this issue of JBC, Ting et al. report proteomic, biochemical, and structural analyses that better explain how the antigen-presenting HLA-DR4 molecules bind citrullinated peptides to provoke rheumatoid arthritis (RA), a chronic autoimmune disease that affects 0.5–1% of the population.
