Heterogeneous Nuclear Ribonucleoprotein A2/B1 as a Target Antigen in Han Chinese for BD Patients

Protein Pept Lett. 2015;22(6):504-8. doi: 10.2174/0929866522666150428121442.

Abstract

Behcet's disease (BD) is a recurrent pathema with a typical symptom of inflammation involved in many organs. Previous report indicated that the serum of Korean patients with BD stimulates membrane expression of hnRNP A2/B1 in endothelial cells. In this study, the target 35 kDa recombinant human hnRNP A2/B1 were over-expressed and purified, then sequenced with MALDI-TOF- TOF mass spectrometry. Western blotting and ELISA were applied to detect serum reactivity against hnRNP A2/B1 respectively. The results demonstrate that hnRNP A2/B1 is an autoantigen of BD in Han Chinese population.
