[0085] VIP signaling regulates alloantigen-induced T cell proliferation

[0086] To explore the role of VIP signaling in the allogeneic immune response, a one-way mixed lymphocyte reaction (MLR) containing VIP and / or antagonist VIPhyb peptides was performed. Addition of VIP decreased luciferase T cell proliferation in a dose-dependent manner, while addition of VIPhyb increased T cell proliferation. VIPhyb reversed the inhibitory effect of VIP in MLR, restoring T cell proliferation to higher levels than control cultures.

[0087] Pharmacological blockade during ex vivo T cell expansion for CAR T manufacturing increases yield and preserves naive and central memory compartments

[0088]Diffuse large B-cell lymphoma (DLBCL) is an aggressive B-cell malignancy that primarily affects older patient populations. Despite robust treatment options, a subset of patients with DLBCL have lymphomas that are highly resistant to treatment. Because the disease in these patients is refractory ...

Abstract

The present disclosure relates to compositions and methods for reversing T cell senescence by disrupting vasoactive intestinal peptide (VIP) signaling and / or inhibiting phosphatidylinositol-3-kinase (PI3-kinase) inhibitor signaling, and for managing cancer and chronic viral infections. In certain embodiments, the present disclosure contemplates methods of reversing T cell senescence by admixing T cells in vitro with agents that prevent the interaction of VIP with VIP receptors and / or PI3 kinase inhibitors. In certain embodiments, the present disclosure contemplates expanding senescent T cells by admixture with PI3 kinase inhibitors, agents that block VIP and VIP receptor signaling, VIP degrading enzymes, and combinations thereof.
