Proteomic Characterization Of Human Multipotent Stromal Cells Secreted Proteins With Therapeutic Potential For Β-Cell Regeneration, Miljan Kuljanin
Proteomic Characterization Of Human Multipotent Stromal Cells Secreted Proteins With Therapeutic Potential For Β-Cell Regeneration, Miljan Kuljanin
Electronic Thesis and Dissertation Repository
Novel strategies to stimulate the expansion of β-cell mass in situ are warranted for diabetes therapy. Cell-replacement therapies for the treatment of diabetes have become a focal point in recent years. Endogenous regeneration of β-cell mass has been demonstrated using human multipotent stromal cells (hMSC). However, the secretory factors responsible for initiating endogenous regeneration remain unknown. Successful large-scale proteomic applications to address these questions have been limited in part by difficulties in correctly selecting the appropriate methodologies. Thus, the goal of this thesis was a combination of assessing different proteomic workflows to facilitate investigation into hMSC biology, applying these methods …
A Clinico-Pathological Study Of The Structural And Functional Changes In The Retina And Optic Nerve Following Diabetic Retinopathy Treatments, Richard Filek
Electronic Thesis and Dissertation Repository
Diabetic retinopathy (DR) is the result of microvascular changes in the retina due to hyperglycemia which alter the blood-retinal barrier (BRB). The increased permeability of BRB results in the accumulation of extracellular fluid, the development of diabetic macular edema (DME) and capillary occlusion. Capillary occlusion results in retinal ischemia which increases vascular endothelial growth factor (VEGF) levels, increases vascular permeability and results in neovascularization in proliferative diabetic retinopathy (PDR) patients. The treatments clinically used for DR are panretinal photocoagulation (PRP) for PDR and injectable vascular endothelial growth factor inhibitors (anti-VEGFs) for DME.
The safety of PRP and anti-VEGF therapy on …
Retinoic Acid Pathway Inhibition To Expand Human Hematopoietic Progenitor Cells With Islet Regenerative Capacity, Ruth Elgamal
Retinoic Acid Pathway Inhibition To Expand Human Hematopoietic Progenitor Cells With Islet Regenerative Capacity, Ruth Elgamal
Electronic Thesis and Dissertation Repository
Cellular therapy to induce islet regeneration is emerging as a novel treatment strategy for diabetes. Umbilical cord blood (UCB)-derived hematopoietic stem/progenitor cells (HSPC) isolated by high aldehyde dehydrogenase activity (ALDHhi) reduce hyperglycemia after transplantation into streptozotocin (STZ)-treated NOD/SCID mice. However, UCB-derived ALDHhi cells are rare and expansion without the loss of regenerative function is required. We hypothesized that BMS 493, an inverse retinoic acid receptor agonist, will prevent HSPC differentiation of HSPC during expansion, generating more ALDHhi cells for therapy. ALDHhi cells expanded for 6 days with BMS 493 showed a 2.70-fold-increase in ALDHhi …
Characterization And Function Of Islet Antigen Presenting Cells During Nod Diabetes, Stephen Thomas Ferris
Characterization And Function Of Islet Antigen Presenting Cells During Nod Diabetes, Stephen Thomas Ferris
Arts & Sciences Electronic Theses and Dissertations
Here we characterized the initial antigen presenting cells (APCs) within the islet of Langerhans to ascertain their identity and functional role as it pertains to autoimmune diabetes. The activation of the adaptive immune system is induced by the innate immune system, and more specifically APCs. Therefore, it is crucial to identify the APCs that are initiating T1D in order to elucidate the break in tolerance and intervene in order to inhibit progression. We have found that there is a resident macrophage that is present in all strains of mice. This islet macrophage has a distinct transcriptional profile that is unique …
An Evaluation Of Gabab Receptors On Modulating Neuroinflammation In A Non-Transgenic Animal Model Of Alzheimer's Disease, Monica Bolton
An Evaluation Of Gabab Receptors On Modulating Neuroinflammation In A Non-Transgenic Animal Model Of Alzheimer's Disease, Monica Bolton
UNLV Theses, Dissertations, Professional Papers, and Capstones
Alzheimer’s disease (AD) is a neurodegenerative disorder characterized by progressive memory loss and distinct neuropathological hallmarks, including amyloid beta plaques and neurofibrillary tau tangles (NFT). Although the etiology remains to be discovered, several risk factors exist that significantly contribute to developing AD. Diabetes is one of the major risk factors associated with AD and is characterized by disrupted insulin signaling that may contribute to or exacerbate AD pathologies. Furthermore, both disorders result in increased neuroinflammation. Considerable evidence has demonstrated that a chronic inflammatory response, in particular chronic microglia activation, promotes A production as well as the hyperphosphorylation of tau through …
