Microglia-Neuron Interactions In A Mouse Model Of Low Grade Neuroepithelial Tumors, Veolette Hanna
Microglia-Neuron Interactions In A Mouse Model Of Low Grade Neuroepithelial Tumors, Veolette Hanna
Honors Scholar Theses
Microglia are the macrophages of the brain and spinal cord, playing an important role in the immune response to disease states of the nervous system. This study conducts an investigation on the activity of microglia in response to low grade neuroepithelial tumors. Using mouse models and microglial markers, a qualitative and quantitative analysis of microglia activation, migration, and invasion within the brain cortex during early stages of tumor development was conducted. It was found that the presence of a low grade neuroepithelial tumor in the cortex of one hemisphere of the brain causes significant microglia activation in comparison to the …

Regulation Of Neuroinflammation After Ischemic Stroke By Astroglial Endothelin Receptor Type-B Signaling, John Mcinnis
Graduate College Dissertations and Theses
A large body of neuroscientific research has focused on reactive gliosis and glial scar formation because these are among the most prominent features of the cellular response to central nervous system (CNS) injury. Despite much progress in our understanding, controversy remains regarding the relative balance between the protective nature of the astroglial scar and its anti-regenerative features. Recent work suggests that astrocytes are heterogeneous in their resting state and in their reactivity. In traumatic injuries such as stroke and spinal cord injury, proliferative reactive astrocytes protect CNS tissue. By contrast, under neuroinflammatory and/or neurodegenerative conditions, neurotoxic astrocyte phenotypes may contribute …
