Biochem/physiol Actions

HBcAg core human is a capsid protein of hepatitis B virus (HBV). It acts as a viral factor for HBV clearance. HBcAg is implicated in viral replication.
Hepatitis B virus core antigen (HBcAg) is a positive control for human HBV antibodies.In humans with chronic HBV (hepatitis B virus) infection, cytotoxic effects of blood T lymphocytes can be suppressed by incubating cells with antibodies against hepatitis B core antigen (HBcAg). The antigen can also work as a T-cell independent antigen in athymic mice. However, it is an efficient immunogen, resulting in T-cell activation and increased anti-HBc levels. High cytoplasmic/membranous expression of HBcAg is associated with increased liver inflammation.

Hepatitis B virus (HBV) chronically infects approximately 350 million people worldwide, and 600 000 deaths are caused by HBV-related hepatic failure. Golgi protein 73 (GP73) is a serum biomarker for liver diseases, including chronic hepatitis B. Here, we determine the effect

A measurable serological response to hepatitis C infection is delayed on average until 70 days after infection. In addition, it may not occur in some immunocompromised people. Detection of free hepatitis C (HCV) core antigen in blood has enabled diagnosis

The intrahepatic distribution of hepatitis B core antigen (HBcAg) and surface antigen (HBsAg) was studied in 32 patients with chronic type B hepatitis, and the results were correlated with the status of hepatitis B e antigen/antibody (HBeAg/anti-HBe) and with the
