The Role Of The Nlrp3 Inflammasome In Alzheimer's Disease, Ethan S. Terman
The Role Of The Nlrp3 Inflammasome In Alzheimer's Disease, Ethan S. Terman
Undergraduate Research Posters
This study examines the consequences of Alzheimer’s in rat and mice test subjects. The goal is to identify the effects of certain NLRP3 inhibiting drugs and to see if there are any noticeable effects in regards to impeding the pathological development of Alzheimer’s disease. The results are visualized by implementing the immunohistochemical process to identify neurodegeneration in the brain and to assess the expression levels of amyloid beta as an indicator of Alzheimer’s pathology. Other tests are also conducted on these transgenic mice to gauge cognitive functioning levels during the onset of their disease, those being behavior tests, but not …
Cardiac Arrest And Global Ischemia Reperfusion Injury: Role Of Mitochondria And Cannabinoid Receptor 2 Signaling., Jennifer L. Bradley
Cardiac Arrest And Global Ischemia Reperfusion Injury: Role Of Mitochondria And Cannabinoid Receptor 2 Signaling., Jennifer L. Bradley
Theses and Dissertations
We explored the effects of cardiac arrest on mitochondria populations and heart whole tissue lysate proteomics utilizing the Weil Institute’s in vivo rat model of cardiac arrest and cardiopulmonary resuscitation. We have discovered that brain mitochondria are more sensitive to global ischemia compared to heart mitochondria. Additionally, complex I is the most sensitive electron transport chain complex to ischemic injury and is a major control point of the rate of oxidative phosphorylation following cardiac arrest and cardiopulmonary resuscitation. Preservation of brain mitochondrial activity and function during cardiac arrest may enhance outcomes and recovery.
A recent article focusing on acute myocardial …
The Effects Of Interleukin-1Β On Cardiac Reserve And Exercise Capacity In The Mouse, Habeebah Z. Vohra
The Effects Of Interleukin-1Β On Cardiac Reserve And Exercise Capacity In The Mouse, Habeebah Z. Vohra
Theses and Dissertations
Heart failure (HF) is characterized by dyspnea, fatigue, and exercise intolerance. Clinical evidence points to increased interleukin-1β (IL-1β) activity in patients with HF, with an IL-1 blockade improving the exercise capacity in HF patients. In healthy mice, recombinant-mouse IL-1β (rmIL-1β) induces acute systolic dysfunction, peaking 4 hours after administration. However, the direct effects of rmIL-1β on exercise capacity are unknown. We hypothesized that rmIL-1β diminishes the exercise capacity in the mouse. Adult mice were trained to run on a treadmill and exercise capacity was assessed before, 4 hours, and 96 hours after intraperitoneal administration of rmIL-1β (3 μg/kg) or vehicle …
The Impact Of Aging And Mechanical Injury On Alveolar Epithelial And Macrophage Responses In Acute Lung Injury And Inflammation, Michael S. Valentine
The Impact Of Aging And Mechanical Injury On Alveolar Epithelial And Macrophage Responses In Acute Lung Injury And Inflammation, Michael S. Valentine
Theses and Dissertations
Patients with severe lung pathologies, such as Acute Respiratory Distress Syndrome (ARDS), often require mechanical ventilation as a clinical intervention; however, this procedure frequently exacerbates the original pulmonary issue and produces an exaggerated inflammatory response that potentially leads to sepsis, multisystem organ failure, and mortality. This acute lung injury (ALI) condition has been termed Ventilator-Induced Lung Injury (VILI). Alveolar overdistension, cyclic atelectasis, and biotrauma are the primary injury mechanisms in VILI that lead to the loss of alveolar barrier integrity and pulmonary inflammation. Stress and strains during mechanical ventilation are believed to initiate alveolar epithelial mechanotransduction signaling mechanisms that contribute …
Counterregulatory Effects Of Ptx3 On Inflammation And Cellular Aging, Aaron L. Slusher
Counterregulatory Effects Of Ptx3 On Inflammation And Cellular Aging, Aaron L. Slusher
Theses and Dissertations
Pentraxin 3 (PTX3) is a vital regulator of innate immune function that has been shown to counterregulate pro-inflammatory signaling and protect against the development of cardiovascular disease (CVD). Less is known about how PTX3 may mitigate against CVD risk by regulating the pro-inflammatory response at the cellular level. Therefore, this dissertation details four manuscripts which aimed to examine the capacity of PTX3 to regulate the innate immune response of peripheral blood mononuclear cells (PBMCs) isolated from healthy adults. Manuscript 1 examined the capacity of PTX3 to alter the inflammatory milieu following in vitro stimulation of isolated PBMCs with the pro-inflammatory …
Post-Tbi Hippocampal Neurogenesis In Different Tbi Models, Kaushal S. Patel
Post-Tbi Hippocampal Neurogenesis In Different Tbi Models, Kaushal S. Patel
Theses and Dissertations
Traumatic brain injury (TBI) leads to short-term and long-term consequences that can cause many different life-long disorders. Studies of TBI have generally focused on the acute stage; however, it is now becoming important to investigate chronic responses following TBI as clinical reports of dementia and cognitive impairments have been linked to a history of TBI. Recent data have established that cognitive function is associated with hippocampal neurogenesis. Chronic injury induced changes in the brain may affect this endogenous process. Chronic responses following TBI include cell death pathways and inflammatory responses that are persistent in the brain for months to years …
Vitamin C: A Potential Regulator Of Inflammatory Response, Bassem M. Mohammed
Vitamin C: A Potential Regulator Of Inflammatory Response, Bassem M. Mohammed
Theses and Dissertations
Introduction: Neutrophils (PMNs) and Macrophages are the first responders recruited consecutively to the site of injury/inflammation. PMNs’ response/fate as well as macrophage reprogramming ultimately determine the course of resolution of inflammation. Physiologic wound healing has a significant inflammatory component. An exaggerated inflammation however is self-defeating leading to delayed healing. Parenteral vitamin C (VitC) attenuated inflammation in murine sepsis models and in patients with sepsis. However information about the mechanisms by which VitC regulates these events is limited.
Methods: Humanized mice lacking VitC synthesis capability (Gulo-/-) were used. VitC sufficient and deficient mice were challenged with sterile inflammation, or …
