    • The present invention is directed to a non-immunogenic cellular composition comprising: a cell having a cell surface and antigenic determinants on the cell surface; a linker molecule covalently attached to the cell surface; and a non-immunogenic compound (e.g., polyethylene glycol or derivative thereof) covalently attached to the linker molecule. In one embodiment, the linker molecule is covalently attached directly to the antigenic determinant on the cell surface. In an alternate embodiment, the linker molecule may be covalently attached to a non-antigenic site on the cell surface, but will camouflage the antigenic determinant on the cell surface by virtue of the long chain length of the non-immunogenic compound. Various uses of the resulting non-immunogenic cell are also provided, including a method of decreasing phagocytosis of a cell, a method of decreasing an adverse reaction to a transfusion, a method of decreasing rejection of a transplanted cell, tissue or organ, and a method of decreasing antibody-induced aggregation of cells.
    • 本发明涉及非免疫原性细胞组合物,其包含:在细胞表面上具有细胞表面和抗原决定簇的细胞; 共价连接到细胞表面的连接分子; 和共价连接到连接分子的非免疫原性化合物(例如聚乙二醇或其衍生物)。 在一个实施方案中,连接体分子与细胞表面上的抗原决定簇直接共价连接。 在替代实施方案中,连接体分子可以共价连接到细胞表面上的非抗原性位点,但是将通过非免疫原性化合物的长链长度伪装细胞表面上的抗原决定簇。 还提供了所得非免疫原性细胞的各种用途,包括减少细胞吞噬作用的方法,减少输血不良反应的方法,减少移植的细胞,组织或器官的排斥反应的方法和 减少抗体诱导的细胞聚集的方法。

    • A chelation structure and method of forming and using the chelation structure. The chelation structure has a backbone that includes a linear sequence of monomeric backbone units, at least one polymer side chain, and at least one chelator side chain. The side chains are each covalently coupled to the backbone at one of the monomeric backbone units by a bond that is independently biodegradable or non-biodegradable. The chelation structure is synthesized by Radical Addition Fragmentation Transfer (RAFT), Atom Transfer Radical Polymerization (ATRP), or Free Radical Polymerization (FRP). The chelation structure, individually or in combination with a shuttle chelator, may be introduced into a mammal to bind an amount of a substance in a mammal, the substance being at least one of a metal and heme. The chelation structure has a log stability constant exceeding that of the shuttle chelator for binding the substance within cells of the mammal.
