Transcription Regulation Of Human Il1b Gene In Monocytes And Lymphoid Cd4 T Cells, Sree H. Pulugulla
Transcription Regulation Of Human Il1b Gene In Monocytes And Lymphoid Cd4 T Cells, Sree H. Pulugulla
Electronic Theses and Dissertations
Cytokines are key regulators of the inflammatory response and play an important role in facilitating intercellular communication between various immune cell types. Interleukin‑1β (IL‑1β) is a potent pro-inflammatory cytokine that is required for robust initiation of innate immune response and subsequent development of adaptive immunity. IL-1β is first synthesized as an inactive cytoplasmic, non‑glycosylated, precursor molecule (proIL‑1β) by monocytes and macrophages in response to invading pathogenic microbes. The activation of caspase‑1 by inflammasomes cleaves proIL-1β into mature biologically active IL-1β that is released from cells via a non-classical, endoplasmic reticulum‑independent secretory pathway directly from the cytoplasm via Gasdermin D membrane …
Nanomedicine-Driven Neuropathic Pain Relief In Rat Model Is Associated With Macrophage Polarity And Mast Cell Activation, Muzamil Saleem
Nanomedicine-Driven Neuropathic Pain Relief In Rat Model Is Associated With Macrophage Polarity And Mast Cell Activation, Muzamil Saleem
Electronic Theses and Dissertations
We explored the immune neuropathology underlying multi-day relief from neuropathic pain in a rat model initiated at the sciatic nerve by using a nanoemulsion-based nanomedicine as a biological probe. The nanomedicine is theranostic: both therapeutic (containing celecoxib drug) and diagnostic (containing near-infrared fluorescent (NIRF) dye) and is small enough to be phagocytosed by circulating monocytes. A model of neuropathic pain is initiated by tying four 1mm spaced knots around the sciatic nerve with chromic gut suture, which results in neuroinflammation, and a resultant pain-like behavior manifests. We show that pain-like behavior reaches a plateau of maximum hypersensitivity 8 days post-surgery, …
Novel Mechanisms And Biomarkers In Alcohol-Induced Organ Injury., Christine E. Dolin
Novel Mechanisms And Biomarkers In Alcohol-Induced Organ Injury., Christine E. Dolin
Electronic Theses and Dissertations
Background. Ethanol (EtOH) consumption is known to affect multiple organs; this is unsurprising, as the concentration of EtOH in the blood at relevant doses reaches the millimolar range. The overarching goal of this dissertation was to elucidate mechanisms of alcohol-induced organ injury, specifically the effects of alcohol on the hepatic extracellular matrix (ECM) proteome, the alcoholic hepatitis (AH) plasma peptidome, and the effects of alcohol on the renal cortex proteome and transcriptome. Methods. Mice were pair-fed ethanol-containing liquid diet chronically, and then some mice were administered lipopolysaccharide (LPS). Liver sections from these mice were processed in a series of increasingly …
Are Chronic Inflammatory Diseases Associated With Trauma Exposure And Gender? An Empirical Analysis Of Self-Reported Trauma And Health Histories Of Men And Women, Meghan Lacienski
Are Chronic Inflammatory Diseases Associated With Trauma Exposure And Gender? An Empirical Analysis Of Self-Reported Trauma And Health Histories Of Men And Women, Meghan Lacienski
Electronic Theses and Dissertations
A growing body of research indicates an association between trauma, inflammation, and chronic inflammatory disease; however, the mechanisms of this relationship are not fully understood, and the salience of potential risk factors, such as cumulative effects of trauma, trauma type, and gender, remain unclear. Trauma is associated with poor mental and physical health, such as PTSD, depression, and chronic inflammatory conditions, and this association may be stronger when certain risk factors are considered (Brody, Pratt, & Hughes, 2018; Groer, Kane, Williams, & Duffy, 2014; Husky, Mazure, & Kovess-Masfety, 2018; Kilpatrick et al., 2013). For example, sexual trauma and multiple traumatic …

Bovine Cellular And Innate Immune Response To Hemostatic Polysaccharides, Brian Kobylkevich
Electronic Theses and Dissertations
Chronic wounds are longstanding dermal wounds that do not heal in a normal amount of time and can commonly last for over a year. These wounds plague humans and farm animals alike. Wounds are characterized by chronic inflammation and are often painful, difficult to heal, have a high recurrence rate, and are potentially debilitating. Long term wounds that do not fully heal are distressing for both humans and animals, but understandably more resources have been directed towards humans. Some treatment options for humans may be suitable for adaptation into the field of animal care. Chronic lesions such as bovine digital …
Mechanisms Of Fibrosis In Regeneration Of Aged Skeletal Muscle, Fasih Ahmad Rahman
Mechanisms Of Fibrosis In Regeneration Of Aged Skeletal Muscle, Fasih Ahmad Rahman
Electronic Theses and Dissertations
Skeletal muscle is a highly adaptive tissue that possesses the ability to regenerate following damage. Regenerative capacity of skeletal muscle declines as age advances, leading to restricted mobility and poor quality of life. The impairment of the regeneration process in aged muscle is partly due to the accumulation of structural proteins in the extracellular matrix (ECM), termed fibrosis. In this study, two important proteins regulating ECM remodeling, plasminogen activator inhibitor-1 (PAI-1) and matrix metalloproteinase-9 (MMP-9), were investigated to determine their role in modulating changes in the ECM during aged muscle regeneration. The regeneration process was studied in young (3 month …
