Patent number: 8980324Abstract: The invention relates to ultrasmall, monodisperse nanoparticles comprising silicon dioxide to the surface of which at least one antigen is attached. The nanoparticles can be used for the immunoprophylaxis or immunotherapy of cancer. The invention also relates to a method for the targeting of antigens at antigen-presenting cells and for the activation of the immune system, where the efficiency of targeting and/or immunoactivation are set via the particle characteristics. The invention also relates to a method for the active and passive immunization of a mammal.Type: GrantFiled: July 13, 2009Date of Patent: March 17, 2015Assignee: Merck Patent GmbHInventors: Markus Weigandt, Andrea Hanefeld, Armin Kuebelbeck, Gregor Larbig

Publication number: 20150072007Abstract: The present invention relates to a non-invasive medical therapy and a composition for avoiding organ transplantation, or controlling biological rejection of transplanted organs, or treating organs under consideration for replacement by transplant, and otherwise treating aged, diseased and/or abnormal tissues and/or organs. More specifically, the non-invasive medical therapy involves administering to a patient an elemental nutritional feeding comprising a free amino acid profile simulating and/or replicating a targeted diseased or transplanted tissue and/or organ. The subject invention provides methods of inactivating reactive component epitopes of moieties pathogenic substances or producing immunogenic compositions containing pathogenic substances comprising contacting pathogenic substances, or compositions containing pathogenic substances, with super critical carbon dioxide or liquid nitrogen. Similar benefits are produced using high HLB surfactants also reducing carcinogenic factors.Type: ApplicationFiled: September 11, 2014Publication date: March 12, 2015Inventor: LEONARD S. GIRSH
