Expression pattern of MiR-146a and its correlation with antibody titers in human brucellosis / 中国免疫学杂志

ABSTRACT

Objective:To investigate the expression pattern of microRNA-146a in Brucella patients and its correlation with antibody titers.Methods: By using real time PCR assay, expression levels of microRNA-146a in sera samples from 20 brucellosis patients and 20 healthy volunteers were analyzed.The correlation between expression level of microRNA-146a and serum antibody titers were analyzed with SPSS17.0.Results: A quantification curve of microRNA-146a was constructed with synthesized standard.Expression levels of microRNA-146a among brucellosis patients were significantly lower than those in 20 healthy volunteers (P<0.001).For brucellosis patients,the expression level of microRNA-146a was negatively related with antibody titers (P<0.05). Conclusion:Expression of miRNA-146a in brucellosis patients was significantly inhibited and negatively related with antibody titer.
