Abstract

Rheumatoid arthritis(RA)is an inflammatory autoimmune disease triggered by antigenic peptides with environmental and genetic risk factors.It has been shown that antigen-specific targeting could be a promising therapeutical strategy for RA by restoring immune tolerance to self-antigens without compro-mising normal immunity.Citrullination of antigens enhances antigenic properties and induces autoim-mune responses.Here,we showed that citrullinated antigenic(citAg)vaccine ameliorated collagen-induced arthritis with decreased T-helper 1(Th1)and Th17 cells,downregulated proinflammatory cytokines including interlukin-6 and tumor necrosis factor-α,and inhibited antigen recall responses.B cell receptor sequencing further revealed that citAg vaccine could dampen the dysregulated V(D)J recom-bination,restoring the immune repertoire.Taken together,the results demonstrated that citAg vaccine might have a therapeutic effect on RA.
