Development Of Methods To Modulate Natural Killer Cells, Kari A. Shaver
Development Of Methods To Modulate Natural Killer Cells, Kari A. Shaver
Honors Undergraduate Theses
Natural Killer (NK) cell based immunotherapies have demonstrated success against malignancies and hematological cancers. However, tumors have developed mechanisms to evade detection by and suppress the immune system, commonly through altering the expression of cell-surface proteins. Overexpression of human leukocyte antigen-E (HLA-E), which binds to the inhibitory NKG2A on NK cells, protects malignant cells from lysis. Downregulating the NKG2A receptor on NK cells should release NK cell inhibition, but proves challenging as NK cells are difficult to transfect and no good methods currently exist. This project is designed to investigate the use of exosomes – small vesicles and natural carriers …

The Effect Of K562-Il21-2 Plasma Membrane Particles On The Proliferation Of Natural Killer Cells To Fight Cancer, Michelle Prophete
Honors Undergraduate Theses
Immunotherapy has emerged as a current and future paradigm of cancer treatment, which utilizes the body’s immune system to eradicate cancer. Natural Killer (NK) cells as part of the innate immune system have immense potential in their anti-tumor cytotoxic activities and host cell surveillance properties. NK cells comprise approximately five to fifteen percent of peripheral blood lymphocytes and can be proliferated in vitro using recently developed methods with co-cultures with feeder cells (derived from engineered tumor cells) or plasma membrane (PM) particles, produced from the fore mentioned feeder cells, in combination with soluble cytokines. For efficient growth and maintenance of …
Activation And Expansion Of Natural Killer Cells For Cancer Immunotherapy With Ex21 Exosomes, Sara Khederzadeh
Activation And Expansion Of Natural Killer Cells For Cancer Immunotherapy With Ex21 Exosomes, Sara Khederzadeh
Honors Undergraduate Theses
In the field of cancer immunotherapy, NK cells are recognized for their ability to provide a form of innate immunity against tumor cells. However, the average abundance of NK cells in the blood can be as low as 5% of the total lymphocyte population. As a result, it has been a focus to find novel therapies to expand NK cells in vitro while subsequently enhancing the cytotoxicity of these cells. Previously-defined methods include the minimal expansion of NK cells with high levels of cytokines such as IL-2 and IL-15, as well as co-culturing NK cells with feeder cell populations that …
