  • Publication number: 20240131151
    Abstract: The present application relates to an immunostimulatory composition including a liposome-nucleic acid complex wherein said complex contains (1) a liposome which, interms of its lipids, includes or consists of a first lipid and a second lipid, wherein the first lipid is a zwitterionic lipid and the second lipid is a cationic lipid, and (2) one or more immunostimulatory oligonucleotides and/or one or more polynucleotides. The application further relates to certain uses of the immunostimulatory composition and to methods for preparing the same. In particular, the application concerns the use of a zwitterionic lipid in an immunostimulatory composition including a liposome-nucleic acid complex to induce type I interferon immune responses and/or to reduce or even bypass TLR-mediated immune responses.

  • Patent number: 6234464
    Abstract: A microencapsulated unsaturated fatty acid or fatty acid compound or mixture of fatty acids and/or fatty acid compounds, and particularly an omega-3-fatty acid or omega-6-fatty acid or an ethyl ester or a glyceride thereof or a mixture of such fatty acids and/or fatty acid compounds. Fatty acid compounds are understood to include derivatives. Particles of the compounds are provided with capsule walls composed of two layers. The inner layer is composed of gelatin A, gelatine B. casein or an alginate, or of a derivative or salt of one of these polymers. The outer layer is composed of gelatin B, gum arabic, pectin or chitosan or a derivative or salt of one of these polymers.
