Interleukin 10 (IL-10) is a central immunoregulatory cytokine with important effects on B-cells. We have studied the influence of IL-10 promoter polymorphisms on the immune response to HBsAg and hepatitis A vaccination. We vaccinated 202 twin pairs in an open prospective study with a combined recombinant HBsAg/inactivated hepatitis A vaccine. IL-10 promoter polymorphisms were investigated in all individuals and their influence on anti-HBs, and anti-HAV responsiveness was studied. In the multiple regression analysis accounting for smoking, gender, body mass index and age, the ACC haplotype (-1082, -819 and -592) had a strong influence on anti-HBs production. Individuals carrying the ACC haplotype had anti-HBs titres almost twice as high as individuals without this haplotype. In contrast, anti-HAV production was suppressed by the presence of the -1082A allele in comparison with individuals homozygous for the -1082G allele. The contribution of the shared IL-10 promoter haplotype accounted for 27%of the genetic influence on anti-HBs antibody response. In conclusion, genetic variability in the IL-10 promoter is an important modulator of the immune response against hepatitis viral antigens.展开更多
