Uncovering The Role Of Apoe4 On Alzheimer’S Disease-Related Neuroinflammation, Courtney Marie Kloske
Uncovering The Role Of Apoe4 On Alzheimer’S Disease-Related Neuroinflammation, Courtney Marie Kloske
Theses and Dissertations--Physiology
Alzheimer’s disease (AD) is the most common neurodegenerative disease and is characterized by two hallmark pathologies: amyloid-beta plaques (Ab plaques) and hyperphosphorylated, aggregated tau tangles. These pathologies are typically accompanied by the presence of neuroinflammation which is primarily mediated by microglia. Interestingly, several genetic risk factors that increase the risk of AD also have direct impacts on neuroinflammation. Of interest, Apolipoprotein E (ApoE) is the largest genetic risk factor for AD. ApoE has three isoforms- E4 confers an increased risk for AD, E3 is considered the “control” phenotype, and E2 is protective against AD. E4 plays a role in virtually …
Protein Kinase A And Epac Mediate Chronic Pain After Injury: Prolonged Inhibition By Endogenous Y1 Receptors In Dorsal Horn, Weisi Fu
Theses and Dissertations--Physiology
Inflammation or nerve injury sensitizes several populations of nociceptive neurons in the dorsal horn of the spinal cord, including those that express the neuropeptide Y (NPY) Y1 receptor (Y1R). Our overall hypothesis is that after tissue or nerve injury, these Y1R-expressing neurons enter a state of latent sensitization (LS) that contributes to vulnerability to the development of chronic pain; furthermore, LS is under the tonic inhibitory control of endogenous Y1R signaling. First, we evaluated the intracellular signaling pathways that become activated in Y1R-expressing neurons and participate in LS. To do this, we established behavioral models of inflammatory or neuropathic pain, …
Targeting Methylglyoxal And Ppar Gamma To Alleviate Neuropathic Pain Associated With Type 2 Diabetes, Ryan B. Griggs
Targeting Methylglyoxal And Ppar Gamma To Alleviate Neuropathic Pain Associated With Type 2 Diabetes, Ryan B. Griggs
Theses and Dissertations--Physiology
Neuropathic pain affects up to 50% of the 29 million diabetic patients in the United States. Neuropathic pain in diabetes manifests as a disease of the peripheral and central nervous systems. The prevalence of type 2 diabetes is far greater than type 1 (90%), yet the overwhelming focus on type 1 models this has left the mechanisms of pain in type 2 diabetes largely unknown. Therefore I aimed to improve the current mechanistic understanding of pain associated with type 2 diabetes using two preclinical rodent models: Zucker Diabetic Fatty rats and db/db mice. In addition, I highlight the translational importance …
