The present invention relates to the Respiratory Syncytial Virus, and more particularly to the identification of novel antigens which are useful in particular for the therapeutic and prophylactic treatment of conditions caused by this virus. The present invention relates to methods of generating and/or increasing an immunogenic response directed against Respiratory Syncytial Virus, including subgroups A and B.

Method of generating and/or increasing an immune response against RSV

The invention relates to an adjuvant product which is intended to improve the activity of a molecule when administered to a host, characterized in that it comprises at least one part of the P40 protein of Klebsiella pneumoniae or a protein having at least 80% homology with the P40 protein of Klebsiella pneumoniae. The invention also relates to nucleotide sequences which encode these peptides or proteins and to the use of these sequences as a medicament. More particularly, such DNA sequences can be used in compositions which are intended for immunization by the intramuscular or intradermal route.

Carrier protein having an adjuvant effect

The invention concerns a novel construct for expressing a gene coding for a recombinant protein of interest placed under the control of the Ptrp tryptophan operon promoter in a procaryotic host cell. The invention is characterised in that the construct comprises a nucleic sequence capable of inactivating the gene coding for a TnaA tryptophanase when said nucleic sequence is introduced in said host cell. The invention also concerns vectors containing said construct and host cells transformed by said vectors. The invention further concerns methods for producing said recombinant proteins using said novel constructs.

Constructs for controlled expression of recombinant proteins in prokaryotic cells

A complex of an immunogen and a support molecule, characterized in that the immunogen is coupled covalently to a support molecule, wherein the support molecule is a polypeptide fragment which is able to bind specifically to mammalian serum albumin is disclosed. The invention also relates to the use of such complexes to treat RSV infection, as well as vaccines derived from such complexes.

Complexes of immunogens derived from RSV surface glycoprotein G covalently coupled to a support molecule

Tripartite recombinant DNA encoding fusion proteins which comprise three sequences, i.e., a signal peptide which is operable in a Gram positive bacterium, an immunogenic polypeptide linked thereto which is not normally expressed in a Gram positive bacterium, and a cell wall spanning and a membrane anchoring sequence, as well as their use in Gram positive bacteria to express the resultant fusion protein on their surface are described. The preferred cell wall spanning and anchoring polypeptides include Staphylococcus protein A and Streptococcus protein G.

Recombinant DNA coding for signal peptide, selective interacting
