Abstract
The study of the human immune response to hepatitis B virus (HBV) has been hampered by the lack of an adequate model to evaluate the hepatitis B surface antigen (HBsAg) specific cell response. Thus, this study was conducted to perform an in vitro analysis of the antigenic properties of recombinant HBsAg and demonstrate the influence of variables such as culture time, antigen concentration and cell density on lymphocyte proliferation. Peripheral blood mononuclear cells (PBMCs) were isolated from the venous blood of vaccinated individuals, and in vitro cellular immune responses were evaluated using an HBsAg-specific proliferation assay. Lymphoproliferative responses were detected in culture systems, despite the lack of serum antibodies. Optimal results were obtained when lymphocytes were stimulated at a seeding density of 4×106cells/mL, with 50ng/mL of recombinant HBsAg protein vaccine for 3 days. Data from the present study may contribute to the development of an adequate system to evaluate the cellular immune responses to HBsAg in vaccine recipients.
