The present invention relates to a method for producing and isolating specific immunogenic heat shock proteins from cancer cells or virally infected or recombinant cells and vaccines prepared from such proteins.
摘要:
The present invention relates to a method for isolating and identifying specific immunogenic pathogen-specific peptides associated with stress proteins induced by the treatment of pathogens and pathogen-infected cells with stress inducing stimuli. The invention also relates to the use of the antigenic fragments derived from complexes thereof with heat shock or other stresses proteins as the immunogenic determinant in vaccine compositions.
摘要:
The present invention provides a method for the purification of complexes comprising a stress protein complexed to a peptide or peptide fragment, from a source mixture, typically a cell lysate. The improved method of the invention provides for protein complexes to be purified using ion exchange based methods, without the need to use chemicals such as chaotropes and ampholytes. The purified complexes can be used as the immunogenic determinant in vaccine compositions for the treatment or prevention of infectious diseases or cancerous conditions.
摘要:
The present invention provides an improved method for the purification of a mixture of complexes comprising a stress protein complexed to a peptide or peptide fragment from a source mixture, typically a cell lysate. The method of the invention provides for protein complexes to be purified using ion exchange chromatography based methods, wherein a modified buffer solution is used which results in the purified stress protein complexes being more immunogenic than protein complexes obtained using conventional methodology. The purified complexes can be used to produce improved vaccine preparations which elicit enhanced immune responses in the subjects to whom the vaccine compositions are administered.
摘要:
The present invention provides a vaccine comprising a microbial pathogen, wherein the microbial pathogen is subjected to a stress inducing stimuli. The stress inducing stimuli can be heat or osmotic stress, through preferably the microbial pathogen is genetically modified such that at least one repressor gene for a heat shock protein gene is inactived, this allowing the constitutive expression of heat shock proteins. In particular the use of heat shock protein repressor mutant bacteria is shown to be effective for inducing immunity when comprised within vaccines of the present invention. The present invention further provides a method for producing a vaccine comprising stressed induced microbial pathogens and further the use of the heat shock protein repressor deletion mutant microbes as vaccine vectors which can be additionally allow the expression of heterologous antigen fragments.
摘要:
The present invention relates to methods for the production of heat shock protein complexes for use in vaccine compositions. In particular, there is provided a method for increasing the level and immunogenicity of heat shock protein complexes produced in cells by subjecting the cells to specific stress inducing stimuli. The invention further extends to the use of heat shock protein complexes produced according to the methods of the invention in the preparation of vaccine compositions for the prevention and treatment of infectious diseases and cancerous conditions.
