Lesional activation of Tc17 cells in Behçet disease and psoriasis supports HLA class I‐mediated autoimmune responses

Lesional activation of Tc17 cells in Behçet disease and psoriasis supports HLA class I‐mediated autoimmune responses

We aimed to determine pathological changes in Behçet disease (BD) skin lesions related to the complex genetic predisposition. In BD, the genetic predisposition may mediate antigen‐specific activation and differentiation of a Tc17 response, possibly targeting endothelial (auto)antigens. Neutrophils recruited by IL‐17A in this process may enhance tissue damage by extensive NET formation (NETosis). Thus, the IL‐23/IL‐17 axis presumably controls neutrophilic inflammation in BD vasculitis in the context of a predominant antigen‐specific CD8+ T‐cell response.
