摘要:
The liposomes of the invention comprise at least one dual layer comprising a mixture formed by a phospholipid (I) with a flow temperature of 20-25 DEG C, and a phospholipid (II) with a flow temperature of 20-60 DEG C. The invention is characterized in that the molar ratio of phospholipid (I) to phospholipid (II) is 5:95 - 30:70. Said liposomes are for use in the production of vaccines.

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.
摘要:
The invention concerns a Bordetella strain deficient in the production of toxin and expressing a hybrid protein comprising at least part of the filamentous hemagglutin (FHA) and at least part of a protein heterologous to FHA. The gene coding for the toxin has been eliminated, or at least partially deleted or mutated so as to produce an inactive toxin. This strain can be used as vaccine. The invention also concerns liposomes containing at least part of the FHA protein and at least one protein heterologous to the FHA protein, and the use of FHA for the stimulation of immune responses.

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.
