Chemotherapy is currently the mainstay of treatment for most cancer patients. Despite its efficacy in eliminating cancer cells, a high percentage of chemotherapy patients eventually relapse or suffer progression of the disease. Immunosurveillance is capable of recognizing and eliminating continuously arising transformed mutant cells, and thus cancer immunotherapy is one of the emerging therapeutic strategies that harnesses the power of the immune system to eradicate chemotherapy-resistant cancerous cells. However, the adverse side effects of chemotherapy impede the therapeutic effects of immunotherapy. Our previous studies demonstrate that lymphoma patients are refractory to clinical immunotherapy because of chemotherapy-induced immune dysfunction. In addition ...

With breakthroughs in synthetic biology, improved cell culture techniques and advanced genetic engineering, it has now become possible to generate bi-specific primary human T cells with desired specificities. One mode of redirecting specificity is the modification of T cells to express chimeric antigen receptors (CARs). Recent studies indicate that natural T cells have distinct biochemical and metabolic features that endow them with short lived effector or long lived memory fates. The central objective of this thesis was to investigate whether the signaling endodomain of CARs could reprogram T cells with pre-specified effector and memory fates. This thesis describes a novel ...
