  • Patent number: 11673955
    Abstract: The present invention relates to targeted prevention of vertical transmission of infection between mother and foetus. More particularly, the invention relates to methods of preventing neonatal Fc receptor (FcRn)-mediated transmission of virus, preferably flavivirus, more preferably Zika virus (ZIKV), from a mother immune to a cross-reactive virus e.g. Dengue virus (DENY) to her foetus, and to reagents that block or inhibit said FcRN-mediated transmission of virus.
    Type: Grant
    Filed: May 10, 2018
    Date of Patent: June 13, 2023
    Assignee: National University of Singapore

  • Patent number: 10245319
    Abstract: Provided are nanoparticles comprising heparin, chitosan, and at least one immunomodulatory agent, e.g. a cytokine. The cytokine can be selected from the group consisting of TNF, IL-12, IL-2, IL-23, IL-1?, IL-10, IL-18, and combinations thereof. Further provided are methods of making a nanoparticle comprising mixing a first composition comprising heparin with a second composition comprising chitosan in the presence of at least one cytokine to form a third composition. Further provided are methods of modulating an immune response comprising co-administering to a subject an antigen or vaccine with nanoparticles comprising heparin, chitosan, and at least one cytokine.
