摘要:
The present invention relates to mucin glycoconjugates, and to a process of producing mucin glycoconjugates. It relates to the biological, pharmaceutical and medical applications thereof. The invention notably provides mucin glycoconjugates which do not require a protein carrier, such as KHL, to induce an immune response (anti-Tn IgG).
摘要:
The present invention relates to a method for preparing carbohydrate T cell epitope conjugates of formula (I): M(T-B)n(I) wherein M, T, B and n are as defined in claim 1.
摘要:
The invention relates to a recombinant protein comprising one or several polypeptides bearing one or several epitopes of one or several HPV antigens, said polypeptides being inserted in the same or different permissive sites of an adenylate cyclase (CyaA) protein or of a fragment thereof, wherein said CyaA fragment retains the property of said adenylate cyclase protein to target Antigen Presenting Cells. It also concerns polynucleotides encoding the same. The recombinant protein or the polynucleotide can be used for the design of therapeutic means against HPV infection or against its malignant effects.

摘要:
The present invention relates to a strain of M. bovis BCG or M. microti, wherein said strain has integrated part or all of the RD1 region responsible for enhanced immunogenicity of the tubercle bacilli, especially the ESAT-6 and CFP-10 genes. These strains will be referred as the M bovis BCG::RDI or M. microti::RD1 strains and are useful as a new improved vaccine for preventing tuberculosis and as a therapeutical product enhancing the stimulation of the immune system for the treatment of bladder cancer. These strains are also useful for the expression and presentation of heterologous antigens and molecule that are of therapeutic or prophylactic interest.
