The Hepatic Immunological Pattern Shaped By Dominant-Subdominant Cellular Interactions Creates A Collective Function Beyond The Function Of Each Cellular Constituent To Orchestrate Progression Of Hepatocellular Carcinoma, Nicholas J. Koelsch
Theses and Dissertations
Abundance of data on the role of inflammatory immune responses in the progression or inhibition of hepatocellular carcinoma (HCC) has failed to offer a curative immunotherapy for HCC. This is largely because of taking reductionist approaches and missing the collective function of the hepatic immune system by focusing on specific immune cell types. To this end, we propose that focusing on the dominant-subdominant patterns of the immune cells would allow understanding of the mechanism by which a collective immune function emerges. To identify the collective immune function through a systems immunology perspective, we performed high-throughput analysis of snRNAseq data collected …
Regulatory T Cells Promote Breast Cancer Progression Through Inhibiting Classical Activation Of Macrophages, Nicholas M. Clark
Regulatory T Cells Promote Breast Cancer Progression Through Inhibiting Classical Activation Of Macrophages, Nicholas M. Clark
Theses and Dissertations
Transient ablation of regulatory T cells has been shown to be effective at hindering tumor growth and metastasis in murine breast cancer model. Based on our lab’s previous work, we have demonstrated that NK cells and CD8+ cytotoxic T cells were not required for the protective effect of Treg cell ablation. However, we also reported that CD4+ helper T cells and IFN-γ were required for the protective effect of Treg cell ablation. Furthermore, we observed that CD11B+ cells responded to Treg ablation therapy by up-regulating target genes of IFN-γ. Therefore, this study aimed to investigate the connection between the myeloid …
Immunotherapy Of Cancer: Reprogramming Tumor/Immune Cellular Crosstalk To Improve Anti-Tumor Efficacy, Kyle K. Payne
Immunotherapy Of Cancer: Reprogramming Tumor/Immune Cellular Crosstalk To Improve Anti-Tumor Efficacy, Kyle K. Payne
Theses and Dissertations
Immunotherapy of cancer has been shown to be promising in prolonging patient survival. However, complete elimination of cancer and life-long relapse-free survival remain to be major challenge for anti-cancer therapeutics. We have previously reported that ex vivo reprogramming of tumor-sensitized immune cells by bryostatin 1/ionomycin (B/I) and the gamma-chain (γ-c) cytokines IL-2, IL-7, and IL-15 resulted in the generation of memory T cells as well as CD25+ NKT cells and CD25+ NK cells. Adoptive cellular therapy (ACT) utilizing these reprogrammed immune cells protected FVBN202 mice from tumor challenge, and overcame the suppressive functions of myeloid-derived suppressor cells (MDSCs). We then …
The Effect Of Lactic Acid On Mast Cell Function, Andrew J. Spence
The Effect Of Lactic Acid On Mast Cell Function, Andrew J. Spence
Theses and Dissertations
This study shows for the first time the effect that L-(+)-lactic acid has on mast cell activation. Lactic acid is a byproduct of anaerobic glycolysis and is associated with inflammatory environments such as wounds, tumors and, asthma. In this study, pre-treatment with lactic acid altered cytokine production by bone marrow-derived mast cells (BMMC). Specifically, lactic acid enhanced cytokine secretion following IgE cross-linking, but decreased IL-33 mediated cytokine production. These effects were altered by genetic background, since C57BL/6 mast cells demonstrated the aforementioned result, but lactic acid had no effect on IgE-mediated cytokine production in 129/SvJ mast cells. The affected cytokines …
