Compositions and methods for evaluating and modulating immune responses by detecting and targeting gata3

The present invention provides markers, marker signatures and molecular targets that correlate with dysfunction of immune cells and are advantageously independent of the immune cell activation status. The present markers, marker signatures and molecular targets provide for new ways to evaluate and modulate immune responses. Specifically, GATA3 and/or FOXOl modulation are provided for use as markers, marker signatures and molecular targets. Therapeutic methods are also provided to treat a patient in need thereof who would benefit from an increased immune response.
