USPTO Abstract
The present disclosure provides an innate immunity cell such as a gamma delta T (gdT) cell, Natural Killer (NK) cell, or macrophage having 2-[3-(1,3-dicarboxypropyl)ureido] pentanedioic acid (DUPA) chemically conjugated to the cell surface. The DUPA-conjugated cells provided herein demonstrate increased cytotoxicity toward cancer cells expressing PSMA. DUPA-conjugated cells can be primary cells or cells of a cell line. Also provided are methods of conjugating DUPA to the surface of NK cells, gamma delta T (gdT) cells, or macrophages and methods of treating cancer using DUPA-conjugated NK cells, gamma delta T (gdT) cells, or macrophages.
