The present invention is related to the fields of molecular biology, virology, immunology and medicine. The invention provides a modified virus-like particle (VLP) comprising a VLP which can be loaded with immunostimulatory substances, in particular with DNA oligonucleotides containing non-methylated C and G (CpGs), and particular peptides derived from MelanA linked thereto. Such CpG~VLPs are dramatically more immunogenic than their CpG-free counterparts and induce enhanced B and T cell responses. The immune response against MelanA peptide analogues optionally coupled, fused or attached otherwise to the VLPs is similarly enhanced as the immune response against the VLP itself. In addition, the T cell responses against the MelanA peptide analogues are especially directed to the Thl type. Antigens attached to CpG-loaded VLPs may therefore be ideal vaccines for prophylactic or therapeutic vaccination against allergies, tumors and other self-molecules and chronic viral diseases.

La présente invention a trait aux domaines de la biologie moléculaire, la virologie, l'immunologie et la médecine. L'invention propose une particule d'aspect viral modifiée comprenant une particule d'aspect viral qui peut être chargée de substances immunostimulatrices, notamment d'oligonucléotides d'ADN contenant des motifs C et G non méthylés, et des peptides particuliers dérivés de Melan-A qui y sont liés. De telles particules d'aspect viral à motifs CpG sont nettement plus immunogènes que leurs homologues exemptes de motifs CpG et induisent des réponses améliorées de lymphocytes B et T. La réponse immunitaire contre les analogues de peptide Melan-A éventuellement couplés, accolés ou liés aux particules d'aspect viral est également améliorée sous la forme d'une réponse immunitaire contre la particule d'aspect viral elle-même. En outre les réponses de lymphocytes T contre les peptides Melan-A sont particulièrement dirigées vers la cellule de type Th1. Des antigènes liés aux particules d'aspect viral chargées des motifs CpG peuvent donc constituer des vaccins idéaux pour la vaccination prophylactique ou thérapeutique contre des allergies, des tumeurs et autres maladies de molécules du soi et virales chroniques.
