  • Publication number: 20200101146
    Abstract: Several embodiments provided in the present disclosure relate to compositions that carry an antigen to which tolerance is desired, the antigen being coupled, bound, or otherwise joined to a targeting moiety, the targeting moiety configured to direct the composition to the liver of a subject. In several embodiments, the antigen in coupled to the targeting moiety by way of a polymeric linker. In several embodiments, the polymeric linker is configured to liberate the antigen in vivo. Methods of using the compositions to reduce and/or prevent unwanted immune responses against an antigen of interest are also provided.

  • Publication number: 20190382479
    Abstract: Peptides that specifically bind erythrocytes are described. These are provided as peptidic ligands having sequences that specifically bind, or as antibodies or fragments thereof that provide specific binding, to erythrocytes. The peptides may be prepared as molecular fusions with therapeutic agents, tolerizing antigens, or targeting peptides. Immunotolerance may be created by use of the fusions and choice of an antigen on a substance for which tolerance is desired. Fusions with targeting peptides direct the fusions to the target, for instance a tumor, where the erythrocyte-binding ligands reduce or entirely eliminate blood flow to the tumor by recruiting erythrocytes to the target.
