  • Patent number: 11806396
    Abstract: This invention describes ways of obtaining nano-particulated adjuvants formed by different synthetic variants of GM3 ganglioside. Depending on the fine structure of the fatty acid in the ceramide of the synthetic GM3, said adjuvants are able to stimulate specifically and in a specialized way the humoral or cellular immune response against accompanying antigens. Particularly, this invention provides immunogenic vaccine compositions that comprise peptides, polypeptides or proteins and the aforementioned nanoparticles, which are formed through the dispersion of hydrophobic proteins of the outer membrane complex (OMC) of Neisseria meningitidis in solutions containing fully synthetic variants of the GM3 ganglioside.

  • Publication number: 20140010829
    Abstract: High affinity antibodies were made to gangliosides expressed on tumor cells. The antibodies can be used analytically, diagnostically, therapeutically, and theranostically. The antibodies may be used to target cytotoxic reagents to tumor cells, thus minimizing full-body toxicity. The antibodies may also be used with out added cytotoxin. The antibodies may be detectably labeled or labelable for analytic and diagnostic purposes. The combination of specificity and affinity of the antibodies render them particularly useful.
