Abstract: The invention relates to the finding that virus like particles (VLPs) can be loaded with immunostimulatory substances, in particular with DNA  oligonucleotides containing non-methylated C and G (CpGs). Such CpG- VLPs are dramatically more immunogenic than their CpG-free counterparts and induce enhanced B and T cell responses. The immune response against antigens 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 both the VLPs and antigens are especially directed to the Thl type. Antigens attached to CpG-loaded VLPs may therefore be ....sim.  ideal vaccines for prophylactic or therapeutic vaccination against allergies, tumors and other self-molecules and chronic viral diseases.
