Constitutive expression of costimulatory ligands on adoptively transferred T lymphocytes
First Claim
1. An immunoresponsive cell comprising an exogenous co-stimulatory ligand and a receptor that binds an antigen, wherein the exogenous co-stimulatory ligand is 4-1BBL, a combination of 4-1BBL and CD80, or a combination of 4-1BBL and CD86, wherein the immunoresponsive cell is selected from the group consisting of a T cell, a Natural Killer (NK) cell, a cytotoxic T lymphocyte (CTL), and a regulatory T cell.

Abstract
The present invention provides immunoresponsive cells, including T cells, cytotoxic T cells, regulatory T cells, and Natural Killer (NK) cells, expressing at least one of an antigen-recognizing receptor and a co-stimulatory ligand and methods of use therefore for the treatment of neoplasia and other pathologies where an increase in an antigen-specific immune response is desired.
