Publication number: 20110097417Abstract: 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 Th1 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.Type: ApplicationFiled: May 11, 2009Publication date: April 28, 2011Applicant: Cytos Biotechnology AGInventors: Martin F. BACHMANN, Vania Manolova, Edwin Meijerink, Karl G. Proba, Katrin Schwarz

Publication number: 20110070267Abstract: The invention relates to the finding that virus like particles (VLPs) can be loaded and packaged, respectively, with DNA oligonucleotides rich in non-methylated C and G (CpGs). If such CpG-VLPs are mixed with antigens, the immunogenicity of these antigens are dramatically enhanced. In addition, the T cell responses against the antigens are especially directed to the Th1 type. Surprisingly, no covalent linkage of the antigen to the VLP is required; it is sufficient to simply mix the VLPs with the adjuvants for co-administration. In addition, it was found that VLPs did not enhance immune responses unless they were loaded and packaged, respectively, with CpGs. Antigens mixed with CpG-packaged VLPs may therefore be ideal vaccines for prophylactic or therapeutic vaccination against allergies, tumors and other self-molecules and chronic viral diseases.Type: ApplicationFiled: May 28, 2010Publication date: March 24, 2011Inventors: Martin F. Bachmann, Wolfgang A. Renner

Publication number: 20090074851Abstract: Liposomes are known to enhance the activity of K- (B-) type CpGs which trigger the production of IL-12. In the present invention, the surprising finding was made that liposomes also enhance the activity of D- (A-) type CpGs, leading to the production of IFN? in vivo. These findings are relevant for the humans situation, since IFN? rather than IL-12 is the key cytokine for the induction of Th1 responses and anti-viral protection in humans.Type: ApplicationFiled: July 11, 2008Publication date: March 19, 2009Applicant: Cytos Biotechnology AGInventors: Martin F.
