Analysis Of The Molecular Mechanisms Governing Fcγ Receptor Activation On The Surfaces Of Macrophages By Advanced Optical Microscopy, Elizabeth Michelle Bailey Jan 2019

Analysis Of The Molecular Mechanisms Governing Fcγ Receptor Activation On The Surfaces Of Macrophages By Advanced Optical Microscopy, Elizabeth Michelle Bailey

Electronic Theses and Dissertations

Therapeutic antibodies are achieving new levels of therapeutic success in treating cancers and immunological disorders by antibody engagement of Fc receptor-directed immune responses. Conversely, inhibiting autoantibody induced Fc receptor activation is an attractive approach to treat autoimmune diseases. Immunoglobulin G (IgG) antibodies are often the principal subclass used in therapeutic antibodies and associated with autoimmune pathologies because of their long circulation and potent effector functions, including activation of the Fcγ Receptor (FcγR). Thus, a thorough understanding of the FcγR activation is required to improve the efficacy of immunotherapies and to mitigate autoimmunities. It is well established that FcγR clustering is …


Wetland Biogeochemical Responses To Predicted Climate Change Scenarios, Angela R. Shaffer Jan 2019

Wetland Biogeochemical Responses To Predicted Climate Change Scenarios, Angela R. Shaffer

Electronic Theses and Dissertations

Wetlands are one of the world's largest known carbon sinks while comprising only a small amount of the Earth's surface. However, the amount of carbon sequestered by wetlands is shrinking as droughts and human disturbance increases. Carbon in wetlands is stored through the contrast of decomposition and sedimentation of organic matter and absorption of CO2 from the atmosphere by soil microbes. Understanding how changing hydrological regimes and increased wildfires will affect wetland soil and microbial processes is important in the face of predicted climate change for future wetland conservation practices. Specifically, I seek to understand the response of southeastern …


Impact Of Seasonal And Host-Related Factors On The Intestinal Microbiome And Cestode Community Of Sorex Cinereus And Sorex Monticola, Katelyn D. Cranmer Jan 2019

Impact Of Seasonal And Host-Related Factors On The Intestinal Microbiome And Cestode Community Of Sorex Cinereus And Sorex Monticola, Katelyn D. Cranmer

Electronic Theses and Dissertations

The intestinal microbiome of mammals plays a significant role in host health and response to environmental stimuli and can include both beneficial native bacteria as well as parasitic worms. In this study, I examined the intestinal cestode and bacterial communities of two closely related species of shrew, Sorex monticola and Sorex cinereus, over a six month period in 2016. Specimens were collected approximately every three weeks from May to October from the Sangre de Cristo Mountains in Cowles, New Mexico. A total of 79 shrews were prepared with the gastrointestinal tracts removed and flash-frozen in liquid nitrogen. An additional …
