ABSTRACT
Objective To explore the influence of three SNPs within interlukinc (IL) 10 promoter region on the expression of interlukin 10 mRNA in childhood systemic lupus erythematosus (SLE),then to determine if the SNPs do associate with the pathogenesis of childhood SLE.Methods The levels of IL 10 mRNA were detected in children with SLE and their parents by Taqman PCR,then the correlations between levels of IL 10 mRNA and haplotypes were assessed.Results The results showed that haplotype GCC was associated with higher level of IL 10 mRNA within children with SLE.Conclusion Haplotype GCC is associated with high secretion of IL 10 within childhood SLE,but not operate independently,and maybe it regulates the high secretion of IL 10 with other susceptible genes of SLE.
