摘要

To identify immunoglobulin (Ig) variable heavy chain (VH) gene us-ages in Korean ankylosing spondylitis (AS) patients, expression level of VH2 genes from peripheral blood mononuclear cells (PBMCs) of 8 AS patients and 9 healthy donors was analysed by quantitative real-time PCR (Q-PCR). Q-PCR re-sults demonstrated VH2 genes were overexpressed in AS patients (Relative amount of mRNA of VH2 genes to a house-keeping gene, 7.13±7.77 vs, 0.68±0.55; p<0.0001). The sequence analysis revealed the majority of them con-tained CDC42 binding protein kinase beta (CDC42 BPB) genes. The insertion of CDC42 BPB gene was confirmed by PCR with primers corresponding CDC42 BPB and CH genes. Our study revealed VH2 overexpression and unique rear-rangement in Ig VH genes from peripheral blood of AS patients. This may imply aberrant immunoglobulin gene rearrangement in B cell occurs in Korean AS pa-tients, which requires further investigation.
