Anti-lamin A/C antibodies in patients with Behçet's disease

Abstract

Lamin A/C has been identified as a target antigen of anti-endothelial cell antibodies in vasculitis. Behçet's disease (BD) is a chronic vasculitis with unclear pathogenesis. Self-antibodies have been found to play an important role in the pathological process of BD. The aim of this study was to verify whether lamin A/C is an autoantigen of BD. First, the human lamin A/C protein was cloned and purified and verified by Western blotting. Next, a homemade ELISA kit was used to test the presence of anti-lamin A/C antibodies in BD patients. This is the first time it has been certified that lamin A/C is an autoantigen of BD. The reactivity of serum IgG against recombinant human lamin A/C was detected in 7 of 31 BD patients (23%) and 3 of 32 healthy controls (HC) (9%).
