Herpes simplex virus (HSV) infection is a possible pathogenic factor in Behçet’s disease (BD). Using proteomics analysis, this study detected a target HSV protein. Serum IgA and IgG reactivities against the identified protein were evaluated in patients with BD and in BD-like mice. A total of 4 protein bands generated by immunoprecipitation were analysed by proteomics, and HSV UL48 was commonly found in both IgA- and IgG-reactive protein bands. Compared with controls, patients with BD and BD-like mice exhibited higher titres of IgA reacting with recombinant HSV UL48 protein. Further proteomics analysis revealed that human heat shock cognate 71 kDa protein (Hsc71) is a cross-reacting target antigen against anti-HSV UL48 antibody. In addition, our data demonstrated a very strong association between serum IgG reactivity against recombinant human Hsc71 and recombinant HSV UL48 in patients with BD. We suggest that HSV infection and impaired human Hsc71 activity may be associated with the activation of autoreactive lymphocytes.Downloads
