ATP-Dependent Agonists of Immune Cells Function as Anticancer Agents

Abstract

The present disclosure provides polypeptide constructs that act as agonists of immune cell function when exposed to sufficient levels of ATP to cause their assembly into dimers or higher level complexes (e.g., trimers, tetramers, etc.). The complexes of the constructs are capable of stimulating immune cells (e.g., cytotoxic CD8+ T cell and/or NK cells) that function to promote anti-tumor immune responses. The constructs may be employed as anticancer agents/therapeutics for the treatment of solid tumors that have elevated levels of ATP.

Dependencies are inferred from the claim text.
