Objective To investigate the expression of HLA DM (DMA and DMB) gene in patients with rheumatoid arthritis (RA) in the Han nationality.Methods HLA DMA, DMB and DRB transcripts in purified peripheral blood B cells with anti CD19 mAb coated magnetic beads from 36 RA patients,26 ankylosing spondylitis (AS) and 33 matched normal control subjects were analyzed by semiquantitative and competitive RT PCR.Meanwhile,the expression of HLA DM and DR proteins was also quantified by Western blot.Results Compared with normal controls or AS patients,only the transcription of HLA DMA and DMB from RA patients was significantly decreased ( P 0 01),but no difference in HLA DRB ( P 0 05).An mean DM∶DR ratio in RA patients was significantly lower than that in normal controls ( P 0 01).The mean ratio of DMA/β actin in RA patients was dramatically decreased compared with that in normal controls at protein level ( P 0 01),but DRA/β actin showed no significant difference between the two groups ( P 0 05).Conclusion This specific HLA DM down regulation might play an important role in the processes of antigen presentation and autoimmune in RA.
