  • Publication number: 20110020226
    Abstract: The present invention pertains to complexes comprising sterols and saponins. The complexes are capable of binding a genetic determinant including a polynucleotide. The complexes may further comprise a lipophilic moiety, optionally a lipophilic moiety comprising a contacting group and/or a targeting ligand, and/or a saccharide moiety. The complexes may further comprise an immunogenic determinant and/or an antigenic determinant and/or a medicament and/or a diagnostic compound. The complexes may in even further embodiments be encapsulated by an encapsulation agent including a biodegradable microsphere. The present invention also pertains to pharmaceutical compositions and methods of treatment of an individual by therapy and/or surgery, methods of cosmetic treatment, and diagnostic methods practised on the human or animal body.

  • Patent number: 7452982
    Abstract: The invention relates to an immunogenic complex comprising at a least one glycoside and at least one lipid, integrated into an iscom complex or matrix, and at least one antigen which antigen is integrated into the iscom complex or coupled on to or mixed with the iscom complex or iscom matrix complex, characterised in that it also comprises at least one enzyme. It also relates to such a complex further comprising at least one peptide which specifically binds to a receptor expressed on a cell capable of antigen presentation, which cell expresses MHC Class I or Class II and to compositions comprising the complexes.

  • Publication number: 20040185057
    Abstract: The present invention describes a therapeutic approach by which malignant or other diseased tissues are at least partly eliminated or removed by action of the diseased individuals own immune system. Provided that the diseased tissue is a cancer the present invention relates to the field of cancer immunotherapy. The basic principle of the invention relies on the establishment of an immune response in the diseased individual against a selected antigen. This is followed by the transfer of the antigen to the diseased cells of the individual by which the elicited immune response is directed against the diseased cells whereby the diseased tissue is eliminated. The immunogen used to induce the immunological response may be, but is not required to be, identical to the antigen. The immuneresponse may exist prior to treatment due to natural infections or may be established by vaccination or by a combination hereof.

  • Patent number: 5785974
    Abstract: An immunogenic peptide for use in the prevention of parvovirus infections having a contiguous sequence of 6 to 25 amino acids. The peptide is produced from autonomous parvoviruses so as to be capable of inducing neutralizing antibodies against such viruses. These peptides correspond to antigenic sites located in the first 25 amino acids of the amino terminal end of the VP2 proteins of parvoviruses. When these peptides are coupled to carrier proteins or to other immunogenic complexes, they can be used in the formulation of vaccines appropriate to protect dogs, cats, pigs and minks against the infections caused by the parvoviruses.

  • Patent number: 5679354
    Abstract: The invention claims an iscom matrix which is not a lipid vesicle comprising at least one lipid and at least one saponim but no intentional antigenic determinants and optionally also adjuvants for use as an immunomodulating agent, medicines, vaccines, kits containing the matrix and new saponins, and a process for preparing the new saponins. The invention also concerns a process for preparing the matrix characterized in that at least one sterol is solubilized in a solvent or detergent, the saponin or saponins are added, the other adjuvants and lipids are optionally also added, whereafter the organic solvent or the detergent may be removed for example with dialysis, ultra filtration, gel filtration or electrophoresis. The sterol and saponin might also be solubilized in the lipids and/or adjuvants.

  • Patent number: 5498413
    Abstract: Method for the production of a subunit vaccine against porcine parvovirus (PPV). The method is comprised of a first step wherein a recombinant protein VP2 of PPV is obtained by using the replication of a recombinant baculovirus wherein the gene corresponding to VP2 has been previously inserted in cells of a permissive host. The protein VP2 obtained in this invention has the capacity of forming empty chimeric capsids with high immunogenicity and can be provided as a vaccine formulation for protecting pigs against PPV infection. The recombinant baculovirus AcMNPV.pPPVEx8 expresses the VP2 of PPV in conditions making possible the formation of pseudo-viral capsids.
