H-2d mice generated a major histocompatibility complex (MHC) class I (Ld)-restricted T-cell response of defined restriction and epitope specificity to the hepatitis B virus small surface antigen (HBsAg). Here, we compare different vaccination techniques that prime in vivo class I-restricted, murine cytotoxic T lymphocyte (CTL) precursors and specific serum antibody responses. CTL were efficiently primed by the injection of low doses of recombinant native HBsAg particles without adjuvants, by the injection of low doses of denatured HBsAg monomers without adjuvants, by infection with recombinant vaccinia virus carrying a HBsAg-encoding gene, or by intramuscular transfer of plasmid DNA encoding HBsAg under appropriate promoter control. The observation that the injection of 100 ng to 1 microgram of native HBsAg "virus-like particles' (VLP) without adjuvants is an exogenous antigen preparation that efficiently primes class I-restricted CTL responses was unexpected. It reveals a novel aspect of the immunogenicity of VLP for T cells.

UI	MeSH Term	Description	Entries
D006514	Hepatitis B Surface Antigens	Those hepatitis B antigens found on the surface of the Dane particle and on the 20 nm spherical and tubular particles. Several subspecificities of the surface antigen are known. These were formerly called the Australia antigen.	Australia Antigen,HBsAg,Hepatitis B Surface Antigen,Antigen, Australia
D006515	Hepatitis B virus	The type species of the genus ORTHOHEPADNAVIRUS which causes human HEPATITIS B and is also apparently a causal agent in human HEPATOCELLULAR CARCINOMA. The Dane particle is an intact hepatitis virion, named after its discoverer. Non-infectious spherical and tubular particles are also seen in the serum.

D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.	Animal,Metazoa,Animalia
D013601	T-Lymphocytes	Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.

D014614	Vaccines, Synthetic	Small synthetic peptides that mimic surface antigens of pathogens and are immunogenic, or vaccines manufactured with the aid of recombinant DNA techniques. The latter vaccines may also be whole viruses whose nucleic acids have been modified.

D014771	Virion	The infective system of a virus, composed of the viral genome, a protein core, and a protein coat called a capsid, which may be naked or enclosed in a lipoprotein envelope called the peplos.

D015395	Histocompatibility Antigens Class I	Membrane glycoproteins consisting of an alpha subunit and a BETA 2-MICROGLOBULIN beta subunit. In humans, highly polymorphic genes on CHROMOSOME 6 encode the alpha subunits of class I antigens and play an important role in determining the serological specificity of the surface antigen. Class I antigens are found on most nucleated cells and are generally detected by their reactivity with alloantisera. These antigens are recognized during GRAFT REJECTION and restrict cell-mediated lysis of virus-infected cells.
