Adoptive cell transfer (ACT) using T cells engineered to express tumor-specific T cell receptors (TCR) holds great promise in treating cancer patients. ACT involves the in vitro generation of large numbers of tumor-specific T cells, which are then administered back to the patient, to establish an in vivo response and effective tumor control. Our lab conducted a phase I clinical trial in which metastatic melanoma patients received systemic infusions of autologous T cells transduced to express a tyrosinase-specific TCR (TIL 1383I). We observed tumor regression in one of seven patients and the development of vitiligo, indicative of T cell-mediated killing …
Characterization Of The Effects Of Sex And Estrogen Receptor Signaling On Antigen-Specific T Cells For Immunotherapy, Flor Cecilia Navarro Negredo

Dissertations
Adoptive cell transfer (ACT) immunotherapy using antigen (Ag)-specific T cells is partially effective treating several malignancies but numerous challenges remain in order to improve its therapeutic potential. The roles of host factors, such as sex hormone receptor signaling, that can affect the T cell anti-tumor function remain understudied. The work performed in this dissertation characterized the role of estrogen signaling on T cell function in vitro, and during ACT immunotherapy against hepatocellular carcinoma (HCC) in vivo. Estrogen signaling through ERa enhanced the expression and secretion of Type I effector cytokines including IFNg, TNFa, and Granzyme B in male and female …
