摘要:
The invention concerns the use of the FHA protein or part of the FHA protein, in free form, as adjuvant of the immune response or as immunostimulant in a human or an animal. The invention also concerns adjuvant and immunostimulatory compositions comprising FHA protein or a fragment thereof, and the use of said compositions for making vaccines.
摘要:
The invention concerns a methylated immunogenic recombinant peptide sequence comprising mycobacterial heparin-binding hemagglutinin. The invention also concerns chemical and enzymatic methods for preparing such a sequence, said sequence being previously produced in a non-methylated recombinant form then methylated by post-translational modification. The invention further concerns recombinant tools, vectors and host cells for implementing post-translational enzymatic methylation of the recombinant HBHA. The invention finally concerns immunogenic compositions comprising methylated, native or recombinant HBHA, such compositions being useful for preparing vaccines against mycobacterial infections.

摘要:
The invention features peptide sequences enabling mycobacteria adhesion to host cells, in particular to epithelial cells. More particularly, the invention features a mycobacterial antigen of the heparin-binding haemagglutinin type (HBHA) obtained from Mycobacterium bovis BCG or Mycobacterium tuberculosis. The invention also features a recombinant peptide sequence enabling mycobacteria adhesion to host cells. The invention particularly features the expression product of an Escherichia coli strain transformed with a nucleotide sequence coding for a protein enabling mycobacteria adhesion to host cells. These peptide sequences can be used in immunogenic compositions, for preparing vaccines against mycobacterial infections, and for mycobacterial infection serological diagnosis.
摘要:
A recombinant DNA containing a sequence (1) coding for a polypeptide heterologous to a filamentous haemagglutinin of Bordetella (Fha) fused within the same reading frame to a sequence (2) located upstream from the first sequence. Said sequence (2) codes for at least a part of the Fha precursor, which part comprises at least the N-terminal region of a truncated mature Fha protein which contains the interaction site of Fha and heparin, and which, when it is itself subjected on its own to the control of a promoter recognised by the cell polymerases of B. Pertussis, and inserted into a B. Pertussis cell culture, is expressed in said culture under the control of said promoter and excreted into the cell culture medium. The invention uses both the abilities of Bordetella, and particularly B. Pertussis, which does not appear to produce extracellular proteases, and the ease with which filamentous haemagglutinins can be isolated from those of the Bordetella synthesising same.
