Actions biochimiques/physiologiques

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.
