HLA-DR antigen of HBV intrauterine infection
Random sampling method,[link widoczny dla zalogowanych], and HLA-DR antigen itself from other factors, but there are still a small sample size due to the problem of inadequate representation. So. HLA-DR antigen and HBV intrauterine infection needs further study to expand the sample size. s! n plus ∞: 2 ∞ 222111112212222774 2003 of Public Health Vol 19 No. 7 Chin. , PublicHealth2003Vo1.19No. 7HBV and (or) its going to be a blood-borne antigen and (or) cell-derived 2 way into the fetus It, s3, is generally believed that early exposure in the development of the immune system to antigens induce immune tolerance. According to the results of transgenic mouse models,[link widoczny dla zalogowanych], meAg through the placenta in the uterus of tmeAg and HBcAg induced T-cell tolerance 【9】. If the fetal immune tolerance to HBV antigens. Then the infected liver cells,[link widoczny dla zalogowanych], circulating viruses and antigens can not be cleared. Once infected the fetus HBV,[link widoczny dla zalogowanych], is likely to become chronic carriers. The results show that,[link widoczny dla zalogowanych], HBeAg positive mothers neonatal HBV intrauterine infection rate up to 18.3% (8]. 9O% or more of them become chronic carriers. Comprehensive literature review and the current results. Speculated that HLA-DR antigens has the potential to affect antigen way was involved in the l {port 3v fetal immune tolerance induced by the process, making it susceptible to intrauterine infection of HBV genetic background.
