The Impact Of Nanopulse Treatment On The Tumor Microenvironment In Breast Cancer: Overturning The Treg Immunosuppressive Dominance, Anthony Nanajian
The Impact Of Nanopulse Treatment On The Tumor Microenvironment In Breast Cancer: Overturning The Treg Immunosuppressive Dominance, Anthony Nanajian
Biomedical Sciences Theses & Dissertations
Nanopulse treatment (NPT) is a high-power electric engineering modality that has been shown to be an effective local tumor treatment approach in multiple cancer models. Our previous studies on the orthotopic 4T1-luc breast cancer model demonstrated that NPT ablated local tumors. The treatment consequently conferred protection against a second live tumor challenge and minimized spontaneous metastasis. This study aims to understand how NPT mounts a potent immune response in a predominantly immunosuppressive tumor.
NPT changed the local and systemic dynamics of immunosuppressive cells by significantly reducing the numbers of regulatory T cells (Tregs), myeloid-derived suppressor cells (MDSCs), and tumor-associated macrophages …
Investigating The Antitumor Effects Of A Dsrna-Nanoparticle Complex In An In Vitro Ovarian Cancer Model, Aaron Lewis
Investigating The Antitumor Effects Of A Dsrna-Nanoparticle Complex In An In Vitro Ovarian Cancer Model, Aaron Lewis
Theses and Dissertations (Comprehensive)
An estimated 1 in 70 women will be diagnosed with ovarian cancer in their lifetime. Despite advanced detection and treatment methods, it remains a silent killer with an expected survival rate of 50%. A developing method in cancer treatment is the use of compounds that stimulate the immune system to aid in the body's fight against the disease. This project focused on the use of the potent immune stimulant double-stranded RNA (dsRNA), commercially available as polyinosinic:polycytidylic acid, poly(I:C), to induce cytotoxicity in two ovarian cancer cell lines; SKOV-3 and OVCAR-3. Some challenges exist with the delivery of dsRNA due to …

Immunotherapy: Therapy Vs. Enhancement, Mariah Daly
Honors Program Theses
The battle against cancer is a long-standing struggle that has resulted in new information and the development of novel medical technologies. Current research aims to figure out a way to reprogram cells and bodily mechanisms to eliminate those cells that are cancerous without destroying healthy cells in the process. Methods which use the body’s own mechanisms, such as immunotherapy, have shown and continue to show potential for specifically targeting cancer cells. Adoptive T cell therapy is one form of immunotherapy that has gained significant attention and focus in the field. Therapies improve conditions up to the normal state of being, …
Identification Of Imiquimod As A Potential Combination For Anti-Cd47 Antibodies In Cancer Therapy, Nicole Brittaney Pang
Identification Of Imiquimod As A Potential Combination For Anti-Cd47 Antibodies In Cancer Therapy, Nicole Brittaney Pang
Scripps Senior Theses
The avenues of targeted immunotherapy offers a promise of less toxic treatment options for those battling different forms of cancer. Specifically, the process of hijacking a patient’s own immune system to fight cancer from within versus using external treatments like chemotherapy which is extremely damaging to the patient. One such avenue includes the usage of monoclonal antibodies as an effective modality for immunotherapy. Cluster of Differentiation 47 (CD47), also known as the ‘don’t eat me signal’, aids in cell proliferation and evasion of phagocytosis and has been found to be a target for stopping tumorigenesis. Previous research has been successful …
Cross-Presentation Is A Source Of Tumor Antigens For Multiple Myeloma Immunotherapy, Alexander A. Perakis
Cross-Presentation Is A Source Of Tumor Antigens For Multiple Myeloma Immunotherapy, Alexander A. Perakis
Dissertations & Theses (Open Access)
Cross-presentation is an essential bridge between the innate and adaptive arms of the immune system where antigen presenting cells (APCs) prime cytotoxic T cell responses. We have recently identified cross-presentation as a mechanism by which solid tumors present exogenous antigens. We therefore hypothesized that multiple myeloma would be capable of cross-presentation as these cells are derived from B cells, known APCs. We explored the capacity of multiple myeloma to cross-present PR1, a human leukocyte antigen (HLA)-A2 nonameric peptide that is derived from neutrophil elastase (NE) and proteinase 3 (P3), and the ability to treat multiple myeloma using PR1-targeting immunotherapies. Here …
