Role Of Interleukin-6 In Cd4 And Cd8 T Cell Effector Functions, Rui Yang
Role Of Interleukin-6 In Cd4 And Cd8 T Cell Effector Functions, Rui Yang
Graduate College Dissertations and Theses
IL-6 is an inflammatory cytokine that contributes to the pathogenesis of many immunological diseases including rheumatoid arthritis, multiple sclerosis, systemic lupus erythematosus, allergic asthma, as well as the protection against infections caused by various pathogens. These are linked to its role in regulating CD4 T cell differentiation and effector function.
Most of these functions are dependent on the IL-6-mediated signaling through the transcription factor Stat3. In this thesis, we identify a novel molecular mechanism by which IL-6 regulates CD4 T cell effector function. We show that IL-6-dependent signal raises the levels of mitochondrial Ca2+ late during activation of CD4 T …

Mitochondrial Structure And Function As A Therapeutic Target In Malignant Mesothelioma, Brian Cunniff
Graduate College Dissertations and Theses
Malignant mesothelioma (MM) is a rare tumor associated with occupational exposure to asbestos with no effective treatment regime. Evaluation of mitochondrial function in human MM cell lines revealed a common tumor phenotype: in comparison to immortalized or primary human mesothelial cells, MM tumor cells displayed a more oxidized mitochondrial environment, increased expression of mitochondrial antioxidant enzymes, and altered mitochondrial metabolism. Earlier work by our laboratory indicated that increases in mitochondrial reactive oxygen species (mROS) in MM cell lines supports expression of FOXM1, an oncogenic transcription factor that contributes to increased cell proliferation and chemoresistance. These studies sought to investigate targeting …
