Article Title: Enhancing antitumor efficacy of chimeric antigen receptor T cells through constitutive CD40L expression
Abstract: Adoptive cell therapy with genetically modified T cells expressing a chimeric antigen receptor (CAR) is a promising therapy for patients with B-cell acute lymphoblastic leukemia. However, CAR-modified T cells (CAR T cells) have mostly failed in patients with solid tumors or low-grade B-cell malignancies including chronic lymphocytic leukemia with bulky lymph node involvement. Herein, we enhance the antitumor efficacy of CAR T cells through the constitutive expression of CD40 ligand (CD40L, CD154). T cells genetically modified to constitutively express CD40L (CD40L-modified T cells) demonstrated increased proliferation and secretion of proinflammatory T<inf>H</inf>1 cytokines. Further, CD40L-modified T cells augmented the immunogenicity of CD40+ tumor cells by the upregulated surface expression of costimulatory molecules (CD80 and CD86), adhesion molecules (CD54, CD58, and CD70), human leukocyte antigen (HLA) molecules (Class I and HLA-DR), and the Fas-death receptor (CD95). Additionally, CD40L-modified T cells induced maturation and secretion of the proinflammatory cytokine interleukin-12 by monocyte-derived dendritic cells. Finally, tumor-targeted CD19-specific CAR/CD40L T cells exhibited increased cytotoxicity against CD40+ tumors and extended the survival of tumor-bearing mice in a xenotransplant model of CD19+ systemic lymphoma. This preclinical data supports the clinical application of CAR T cells additionally modified to constitutively express CD40L with anticipated enhanced antitumor efficacy. © 2015 The American Society of Gene & Cell Therapy.
