BACKGROUND: Chronic hepatitis B virus (HBV) infection is associated with a weak but specific cellular immune response of the host to HBV. Tripeptidyl peptidaseⅡ (TPPⅡ), an intracellular macromolecule and proteolytic enzyme, plays an important complementary and compensatory role for the proteasome during viral protein degradation and major histocompatibility complex class I antigen presentation by inducing a specific cellular immune response in vivo. Based on a previous study, we aimed to explore the role of MHC class I antigen presentation in vivo and the mechanisms that may be involved...

In this study a representative group of Mongolian adults was tested for hepatitis B virus (HBV) and hepatitis C virus (HCV). Screening was conducted at 17 different locations on a randomly sampled group, representative of the Mongolian adult population. A total of 1158 adults, 500 (43.1%) men and 659 (56.9%) women were included. The prevalence estimates of HBV and HCV among the general Mongolian adult population were found to be 11.1%± 1% (SE) and 8.5% ± 0.7% or 207,418 and 160,228 cases, respectively. For HCV the majority of cases are concentrated in older age groups with a prevalence of 25...

REVIEW
Brent M Hanson, Jessie A Dorais
Special considerations must be taken when patients with human immunodeficiency virus (HIV), Hepatitis B, or Hepatitis C desire to achieve pregnancy. Patients with chronic viral illnesses desire children at rates similar to the general population, and options are available to decrease both vertical transmission and viral transmission between partners. Preconception counseling or consultation with fertility specialists is imperative in patients with HIV, Hepatitis B, and Hepatitis C so that reproductive goals can be addressed and optimized...

Heteroaryldihydropyrimidine (HAP) and sulfamoylbenzamide (SBA) are promising non-nucleos(t)ide HBV replication inhibitors. HAPs are known to promote core protein mis-assembly, but the molecular mechanism of abnormal assembly is still elusive. Likewise, the assembly status of core protein induced by SBA remains unknown. Here we show that SBA, unlike HAP, does not promote core protein mis-assembly. Interestingly, two reference compounds HAP_R01 and SBA_R01 bind to the same pocket at the dimer-dimer interface in the crystal structures of core protein Y132A hexamer...

The majority of patients with acute febrile jaundice (>95%) identified through a yellow fever surveillance program in the Democratic Republic of Congo (DRC) test negative for antibodies against yellow fever virus. However, no etiological investigation has ever been carried out on these patients. Here, we tested for hepatitis A (HAV), B (HBV), C (HCV), D (HDV) and E (HEV) viruses, all of which can cause acute febrile jaundice, in patients included in the yellow fever surveillance program in the DRC. On a total of 498 serum samples collected from suspected cases of yellow fever from January 2003 to January 2012, ELISA techniques were used to screen for antibodies against HAV (IgM) and HEV (IgM) and for antigens and antibodies against HBV (HBsAg and anti-HBc IgM), HCV and HDV...

BACKGROUND: Chronic hepatitis B is a common, progressive disease, particularly when viral replication is detected. Oral antivirals can suppress viral replication and prevent or delay the development of cirrhosis and liver-related complications. The treatments of chronic hepatitis B cannot totally cure the disease but can prevent its progression to hepatocellular carcinoma, decreasing the levels of both morbidity and mortality. To date, there are several therapies indicated by the international guidelines as first-line treatments for the management of hepatitis B; two of the most effective are those based on either tenofovir or entecavir...

BACKGROUND: In universal hepatitis B (HB) vaccination, single vaccine-derived polyclonal anti-HBs antibodies (anti-HBs) need to inhibit infection of HB viruses (HBV) of non-vaccine genotypes. We experimentally addressed this issue. METHODS: Anti-HBs-positive sera were obtained by vaccination with genotype A- or C-derived HBs antigen (HBsAg, gtA-sera or gtC-sera). Their reactivity to genotype A- and C-derived HBsAg (gtA-Ag and gtC-Ag) was measured by ELISA. The capacity of sera to neutralize HBV was evaluated using an in vitro infection model...

Lomibuvir (1) is a non-nucleoside, allosteric inhibitor of the hepatitis C virus NS5B polymerase with demonstrated clinical efficacy. Further development efforts within this class of inhibitor focused on improving the antiviral activity and physicochemical and pharmacokinetic properties. Recently, we reported the development of this series, leading to compound 2, a molecule with comparable potency and an improved physicochemical profile relative to 1. Further exploration of the amino amide-derived side chain led to a series of lactam derivatives, inspired by the X-ray crystal structure of related thiophene carboxylate inhibitors...
