Repeated elastin challenge for 1 month resulted in airway remodelling, lung function decline and airspace enlargement. Elastin-specific T cell recall responses were dose dependent and memory lasted for over 6 months. Adoptive T cell transfer and studies in T cells deficient Rag1-/-mice conclusively implicated T cells in these processes. Mechanistically, cigarette smoke exposure-induced elastin-specific T cell responses were matrix metalloproteinase (MMP)12-dependent, while the ensuing immune inflammatory processes were interleukin 17A-driven. Anti-elastin antibodies and T cells specific for elastin peptides were increased in patients with COPD.These data demonstrate that MMP12-generated elastin fragments serve as a self-antigen and drive the cigarette smoke-induced autoimmune processes in mice that result in a bronchitis-like phenotype and airspace enlargement. The study provides proof of concept of cigarette smoke-induced autoimmune processes and may serve as a novel mouse model of COPD.MMP12-generated elastin fragments serve as a self-antigen and drive cigarette smoke-induced autoimmune processes in mice. These findings provide experimental evidence for cigarette smoke-induced autoimmunity and represent a novel mouse model of COPD. https://bit.ly/2XK9dC6}, issn = {0903-1936}, URL = {//www.qdcxjkg.com/content/56/3/2000404}, eprint = {//www.qdcxjkg.com/content/56/3/2000404.full.pdf}, journal = {European Respiratory Journal} }
