A Novel Immunostimulatory Platform For Amplifying The Abscopal Response Rates Of Radiation Therapy, Patrick A. Paez Jan 2021

A Novel Immunostimulatory Platform For Amplifying The Abscopal Response Rates Of Radiation Therapy, Patrick A. Paez

Theses and Dissertations

Radiation therapy (RT) is one of the primary treatment modalities for head and neck squamous cell carcinoma (HNSCC). At the time of diagnosis two-thirds of HNSCC patients have local-advanced disease and 50-60% of these patients will experience a local-regional or metastatic relapse within three years. Improving the immunogenic response of RT may help address this clinical problem. However, current RT regimens have failed to reliably generate robust antitumor immunity as evidenced by the rarity of clinical abscopal responses. Recently we engineered a chimeric fusion molecule called Flagrp170, a novel immunostimulatory agent highly capable of promoting antigen presentation and T-cell activation. …


Immunotherapy Of Cancer: Reprogramming Tumor/Immune Cellular Crosstalk To Improve Anti-Tumor Efficacy, Kyle K. Payne Jan 2015

Immunotherapy Of Cancer: Reprogramming Tumor/Immune Cellular Crosstalk To Improve Anti-Tumor Efficacy, Kyle K. Payne

Theses and Dissertations

Immunotherapy of cancer has been shown to be promising in prolonging patient survival. However, complete elimination of cancer and life-long relapse-free survival remain to be major challenge for anti-cancer therapeutics. We have previously reported that ex vivo reprogramming of tumor-sensitized immune cells by bryostatin 1/ionomycin (B/I) and the gamma-chain (γ-c) cytokines IL-2, IL-7, and IL-15 resulted in the generation of memory T cells as well as CD25+ NKT cells and CD25+ NK cells. Adoptive cellular therapy (ACT) utilizing these reprogrammed immune cells protected FVBN202 mice from tumor challenge, and overcame the suppressive functions of myeloid-derived suppressor cells (MDSCs). We then …
