Modulating Immunometabolism To Improve The Activity Of Car-Nk Cells Targeting Cd70 In Renal Cell Carcinoma, Hind Rafei
Modulating Immunometabolism To Improve The Activity Of Car-Nk Cells Targeting Cd70 In Renal Cell Carcinoma, Hind Rafei
Dissertations & Theses (Open Access)
Despite the approval of several therapies for metastatic clear cell renal cell carcinoma (ccRCC), disease resistance and relapse are common, and therapies with novel mechanisms of action are urgently needed. Chimeric antigen receptor (CAR) T-cell therapy has shown remarkable responses in hematologic malignancies, but many obstacles hinder success in solid tumors including the paucity of highly specific targets and the hostility of the tumor microenvironment (TME). Moreover, the limitations of generating an autologous cell product, such as cost of manufacture, and the challenges of toxicity with CAR-T cells highlight the need to develop new cell therapy products that are at …
The Role Of Il-8-Mediated Src Family Kinase Activation In Tumor-Tumor And Tumor-Stromal Interactions In Metastasis Of Prostate Cancer, Lynnelle Thorpe
The Role Of Il-8-Mediated Src Family Kinase Activation In Tumor-Tumor And Tumor-Stromal Interactions In Metastasis Of Prostate Cancer, Lynnelle Thorpe
Dissertations & Theses (Open Access)
Men with localized prostate cancer (PCa) have a 100% five-year survival rate, but this rate drops to 33% for men with metastatic disease. A better understanding of the metastatic process is needed to develop better therapies for PCa. Aberrant activation of protein tyrosine kinases, including Src Family Kinases (SFKs) contribute to metastasis through numerous functions, one of which leads to increased expression of cytokines, such as IL-8. However, the relationship between Src activity and IL-8 regulation is not completely understood. In cell line models, I determined that IL-8 activates Src and in turn Src activates IL-8 demonstrating a feed forward …
Role Of Mir-19a Released By Inflammatory Breast Cancer Cells In The Regulation Of Dendritic Cell Functions: In Vitro Model Of Crosstalk In The Tumor Microenvironment Of Inflammatory Breast Cancer, Simone Anfossi
Dissertations & Theses (Open Access)
Inflammatory breast cancer (IBC) is a rare but very aggressive form of locally advanced breast cancer (1-6% of total breast cancer patients in United States), with a 5-year overall survival rate of only 40.5%, compared with 85% of the non-IBC patients. So far, a unique molecular signature for IBC able to explain the dramatic differences in the tumor biology between IBC and non-IBC has not been identified. As immune cells in the tumor microenvironment plays an important role in regulating tumor progression, we hypothesized that tumor-associated dendritic cells (TADC) may be responsible for regulating the development of the aggressive characteristics …
Elucidating The Role Of Cd44 Expression On Mesenchymal Stem Cells Within The Tumor Microenvironment, Erika L. Spaeth
Elucidating The Role Of Cd44 Expression On Mesenchymal Stem Cells Within The Tumor Microenvironment, Erika L. Spaeth
Dissertations & Theses (Open Access)
The tumor microenvironment is comprised of a vast array of heterogeneous cells including both normal and neoplastic cells. The tumor stroma recruitment process has been exploited for an effective gene delivery technique using bone marrow derived MSC. Targeted migration of the MSC toward the tumor microenvironment, while successful, is not yet fully understood. This study was designed to assess the role of CD44 in the migration of MSC toward the tumor microenvironment and to determine the implications of CD44-deficient MSC within the tumor stroma. Inhibition of MSC migration was evaluated through a variety of methods in vitro and in vivo …
