Engineering Cxcr2-Ligand-Based Fusion Proteins To Modulate Myeloid Cell Trafficking In Pancreatic Cancer, Benjamin N. Christopher

MUSC Theses and Dissertations

Pancreatic ductal adenocarcinoma (PDAC) has one of the lowest 5-year survival rates of all cancers, and limited treatment options exist. Immunotherapy is effective in some cancer types, but the immunosuppressive tumor microenvironment (TME) of PDAC is a barrier to effective immunotherapy. CXCR2+ myeloid-derived suppressor cells (MDSCs) are abundant in PDAC tumors in humans and in mouse models. MDSCs suppress effector cell function, making them attractive targets for restoring anti-tumor immunity. The studies outlined in this dissertation (1) link tumor-intrinsic oncogenic signaling to dysregulated myeloid activity in PDAC, (2) describe a rationally designed fusion protein and potent inhibitor of CXCR2+ myeloid …

Power Optimized Co-Registration Of Multispectral And Thermal Cameras For Real-Time Urban Pluvial Flood Monitoring, Fatemeh Rezaei

Theses - ALL

Urban pluvial flooding occurs when local precipitation intensity exceeds the capacity of natural and engineered drainage systems, resulting in dangerous and highly localized inundation that is not captured by traditional stream gaging networks. While satellite imagery and flood maps support regional-scale flood management, a critical gap remains in the real-time, spatially continuous, in-situ monitoring of urban surface flooding. To address this monitoring gap, we develop a low-power, camera-based distributed sensor network flood mapping platform, Urban Flood Observation Network (UFO-Net), featuring two co-mounted sensors: a multispectral optical (capturing RGB and Near-Infrared) and a long-wave infrared (thermal) camera.
