Investigating Biological Mechanisms Of Radiation Resistance In Advanced Stage Cervical Cancer, Fiona Ruiz
Investigating Biological Mechanisms Of Radiation Resistance In Advanced Stage Cervical Cancer, Fiona Ruiz
Arts & Sciences Electronic Theses and Dissertations
The current standard of care treatment for locally advanced cervical cancer is curative intent pelvic radiation with concurrently administered platinum chemotherapy (CRT). This treatment strategy is effective for many patients, but 33-50% of patients treated with CRT develop disease recurrence. Metastatic and recurrent cervical cancer is an incurable condition, and many of the currently available treatments are associated with significant morbidity and mortality. Identifying these patients upfront is a challenge that clinicians face when developing treatment strategies. Previous studies used to catalog the genomic and transcriptomic landscape of cervical cancer lacked high quality corresponding clinical follow up data for patients, …
T Cell Immunity In Pancreatic Cancer Is Undermined By Dendritic Cell Dysfunction, Samarth Hegde
T Cell Immunity In Pancreatic Cancer Is Undermined By Dendritic Cell Dysfunction, Samarth Hegde
Arts & Sciences Electronic Theses and Dissertations
Pancreatic cancer carries a dismal prognosis, and desperately needs viable therapeutic interventions beyond chemo-radiation. T cell-dependent immunotherapies have shown great promise in several tumor types, but have not been effective for the vast majority of pancreatic cancer patients. This is, in part, due to our limited understanding of how antigenicity of pancreatic lesions is recognized, and how adaptive immunity is overcome in this disease. We sought to study tumor-immune interactions and identify mechanisms for this immune-failure using several spontaneous and unperturbed mouse models of pancreatic adenocarcinoma. We found that early pancreatic lesions fail to elicit tumor-limiting CD4+ TH1 and CD8+ …
Dissemination Of The Apicomplexan Parasite, Toxoplasma Gondii, Lisa L. Drewry
Dissemination Of The Apicomplexan Parasite, Toxoplasma Gondii, Lisa L. Drewry
Arts & Sciences Electronic Theses and Dissertations
The parasitic protist Toxoplasma gondii is a common pathogen of rodents and felines that also infects humans. The most severe clinical manifestations of toxoplasmosis in humans derive from the systemic dissemination of T. gondii, during which the parasite penetrates biological barriers and accesses protected host compartments such as the central nervous system. T. gondii dissemination is enabled by the intrinsic gliding motility of extracellular parasites, which allows for travel to new host cells and tissues, and also powers the invasion of diverse host cells including migratory leukocytes. Dissemination is further advanced when migrating infected leukocytes shuttle intracellular parasites to new …
