摘要:
The present invention provides a method of inducing or enhancing an immune response to polysaccharides or other T cell-independent antigen by the coadministration of the antigen with bacterial lipoproteins (including covalent attachment of the antigen and lipoproteins). In a preferred embodiment, the lipoprotein of the invention is lipoprotein D.
摘要:
The present disclosure provides modified human herpesvirus glycoprotein B (gB) proteins that incorporate unique mechanisms for generating proteins that mimic their native conformation to enhance their immunogenicity. The modified herpesvirus gB proteins insert a peptide linker at the furin cleavage site in the extracellular domain of herpesvirus gB. When expressed, the gB subunit associates in triplicate to produce a homotrimeric complex, mimicking the native conformation of the gB protein. Also provided are protein complexes comprising a homotrimeric complex of a modified herpesvirus gB protein and herpesvirus gH and gL proteins. Also provided are nucleic acids encoding the modified herpesvirus gB proteins, methods of inducing or suppressing an immune response in a subject by administering a vaccine comprising the modified herpesvirus gB protein, or nucleic acid encoding the same, or a protein complex comprising a homotrimeric complex of the modified herpesvirus gB protein and herpesvirus gH and gL proteins.
摘要:
Cell-free preparations of a cytokine produced by natural killer (NK) cells activated with interleukin 2 (IL-2) or produced by CD4 T cells activated with anti-CD3 monoclonal antibody are described. This cytokine induces antibody secretion by activated B cells. Methods for producing the cell-free supernatants containing the cytokine are also described.
摘要:
Provided are an immunogenic composition comprising polyglycerol phosphate (PGP) and methods for using the composition for treating or preventing staphylococcal infections. The PGP may be conjugated to a T-cell dependent antigen. Also provided are methods for synthesizing PGP and methods for conjugating PGP to a T-cell dependent antigen.
摘要:
A dual carrier immunogenic construct comprised of at least one primary carrier comprising a large molecular weight molecule of greater than 70 kD molecular weight and at least one secondary carrier comprising a T-dependent antigen conjugated to a primary carrier. The dual carrier immunogenic construct may further comprise moieties such as haptens and antigens. Such immunogenic constructs are suitable for use in the diagnosis, treatment, and prevention of diseases.
