摘要:
A method is provided for inducing the adaptive immune response of a patient to an antigen comprising administering to the patient an effective amount of a flagellin protein or peptide fragment thereof to induce an adaptive immune response to said antigen.
摘要:
A method for generating antigen-sensitized Ig-A-producing lymphoblasts in a mammal, using an immunogen comprising an antigen or antigen mixture in association with hydroxylated calcium phosphate (hydroxy apatite) is administered to a mucosal surface of the mammal.
摘要:
A purified immunogenic polypeptide comprises an epitope unit recognized by a protective monoclonal antibody having a high affinity and a high specificity for a surface polysaccharide of a pathogenic microorganism of bacterial, viral, or fungal origin. The polypeptide is capable of inducing an immune response in vivo against the pathogenic microorganism. The immune response confers protection in mice against challenge with the virulent microorganisms.
摘要:
Method of eliciting in a mammalian host a protective immune response to Helicobacter infection and treatment of Helicobacter infection by administering to the host an immunogenically effective amount of a Helicobacter urease or urease subunits as antigen. Vaccine compositions are also provided.
摘要:
The invention features methods for isolating immunoglobulin variable region genes, and the use of these genes in the production of chimeric and isotype switched antibodies. The invention also features substantially pure DNA encoding a variable region of the antibody produced by hybridoma cell line HNK-20, and chimeric antibodies containing this variable region.
摘要:
This application relates to the use of attenuated prokaryotic miccrooganism strains (such as Salmonella) expressing nucleic acid encoding HPV proteins as vaccines against HPV infection and he associated increased risk of cancer. In particular, the work shows that it is possible to assemble VLPs in a prokaryotic organism and that nasal immunization of mice with the strains HPV-specific conformationally dependent and neutralizing antibodies in serum and genital secretions. The experiments described herein show that it is also possible to assemble chimeric VLPs of a HPV including a fusion partner and that tumor protection can be induced.
摘要:
Attenuated strain of a prokaryotic microorganism, being an attenuated strain of Salmonella suitable for use in a live vaccine for administration to a human or animal, in which the microorganism is transformed with nucleic acid encoding Human papilloma virus 16 L1 major capsid protein. The protein assembles in the microorganism to form virus-like particles (VLPs) that are capable of illiciting an immune response sufficient to produce neutralizing antibodies in serum and genital secretions specific for Human papilloma 16 infection when the microorganism is administered to the human or animal body.
