Description
Malignant brain tumors are devastating despite aggressive treatments such as surgical resection, chemotherapy and radiation therapy. The average life expectancy of patients with newly diagnosed glioblastoma is approximately 15 months. One novel therapeutic strategy involves using a ketogenic diet (KD) which increases circulating ketones and reduces circulating glucose. While the preclinical work has shown that the KD increases survival, enhances radiation and alters several pathways in malignant gliomas, its impact on the anti-tumor immune response has yet to be examined. This dissertation demonstrates that mice fed the KD had increased tumor-reactive innate and adaptive immune responses, including increased cytokine production and cytolysis via tumor-reactive CD8+ T cells. Additionally, we saw that mice maintained on the KD had increased CD4 infiltration, while T regulatory cell numbers stayed consistent. Lastly, mice fed the KD had a significant reduction in immune inhibitory receptor expression as well as decreased inhibitory ligand expression on glioma cells, namely programmed death receptor -1 (PD-1) and its ligand programmed death receptor ligand -1 (PD-L1). Further, it is demonstrated that the ketone body beta-hydroxybutyrate (BHB) reduces expression of PD-L1 on glioma cells in vitro suggesting it may be responsible in part for immune-related changes elicited by the KD. Finally this dissertation also shows that the KD increases the expression of microRNAs predicted to target PD-L1 suggesting a potential mechanism to explain the ability of the KD to modulate immune inhibitory checkpoint pathways. Taken together these studies shed important light on the mechanisms underlying the KD and provide additional support for its use an adjuvant therapy for malignant glioma.

Description
This Project Report documents the accomplishments of an extraordinary group of students, faculty, and staff at the Arizona state University, who participated in a year-long, multidisciplinary, first-of-its-kind academic endeavor entitled “The Making of a COVID Lab.” The lab that is the focus of this project is the ASU Biodesign Clinical Testing Laboratory, known simply as the ABCTL.

Description
Under the direction of Dr. Carolyn Compton, a group of seven Barrett honors students have embarked on a truly unique team thesis project to create a documentary on the process of creating a COVID-19 testing laboratory. This documentary tells the story of the ASU Biodesign Clinical Testing Laboratory (ABCTL), the first lab in the western United States to offer public saliva testing to identify the presence of COVID-19.
