尽管HBeAg非病毒颗粒所必需,HBeAg阳性的野生病毒株更容易传播,precore(编码HBeAg)在进化上看是保守的[3]。究其原因,这一现象与HBeAg对宿主免疫的负性调节有利于HBV感染建立和慢性化有关[4]。对应的,precore编码区G1896A终止密码子突变...
总结新生儿发生暴发性肝炎的情况并不常见,但死亡率很高,往往由病毒性肝炎引起的并发症导致,也可能与病毒抗原诱导的机体过度免疫反应有关。其诊断标准是高滴度的anti-HBc IgM。通过对HBV基因组尤其是前C区的序列分析,作者发现在第1896...

All were HbeAg positive, and 6/34 were anti-HbCore IgM positive, indicative of acute infection. Where tested, the predominant genotypes were B and C, occurring in 16/32 and 11/32 respectively. Genotype D was noted in 4/32 women. One woman was co-infected with Hepatitis C.Mean viral ...

The core of the problem is that OBI cannot be easily diagnosed and, for this reason, any HBcAb positive/HBsAg negative patient should be considered a possible occult infection carrier. What we know from literature is that onco-hematological diseases have the major risk of OBI reactivation, ...
blood specimens from different groups of consenting subjects in Benue State, were screened by ELISA for Hepatitis B surface antigen (HBsAg), hepatitis B surface antibodies (HBsAb), hepatitis B core antibodies (HBcAb), hepatitis Be antigen (HBeAg) and Hepatitis B core IgM antibodies (HBcIgM). ...

(D and E) The frequency of HBV-specific cells in and the expression of indicated surface markers on intrahepatic CXCR5+CD8+ and CXCR5−CD8+T cells from 8 HLA-A2 positive patients with HBV-related HCC were detected by using MHC-I pentamers targeting the HBV core 18–27 epitope (FLPSDFF...
