Cell-Type Specific Apoe4 To Apoe2 ‘Switching’ In Astrocytes And Microglia Alters Alzheimer’S Disease Neuropathology, Lesley R. Golden
Cell-Type Specific Apoe4 To Apoe2 ‘Switching’ In Astrocytes And Microglia Alters Alzheimer’S Disease Neuropathology, Lesley R. Golden
Theses and Dissertations--Physiology
Apolipoprotein E (APOE) is the strongest genetic risk factor for late-onset Alzheimer’s disease (LOAD). APOE exists in three common protein isoforms throughout the population: ApoE2 (E2), ApoE3 (E3), and ApoE4 (E4). While APOE allele frequencies and the degree of AD-associated risk vary across different ethnic groups, when compared to the ‘neutral’ and most common E3 allele, the E4 allele confers up to a 33-fold increase in Alzheimer’s Disease (AD) risk. Conversely, the neuroprotective E2 allele decreases AD risk by up to 67%. Here, we aimed to determine the therapeutic potential of cell-type specific APOE allele ‘switching’ and explore …

The various cells that support neurons in both the central and peripheral nervous systems are known collectively as neuroglia, or glia. Astrocytes, a type of glial cell found exclusively in the central nervous system (i.e. the brain and spinal cord), are particularly abundant and serve many functions. One of the most important is the role these cells play in the brain as a defense against harmful substances, many of which can be found in the environment and make their way into the human body as xenobiotic substances. Elemental arsenic in its inorganic form occurs naturally throughout the Earth’s crust, but …

In the adult mammalian brain and spinal cord, neuronal injury results in failed neurite regeneration, in part due to the up-regulation of chondroitin sulfate proteoglycans (CSPGs). CSPGs are molecules consisting of a protein core with covalently bound glycosaminoglycans (GAGS), specifically, chondroitin sulfate side-chains. The majority of CSPGs produced after injury originate from reactive astrocytes found in the glial scar surrounding the injury site. Although this milieu is very complex and involves more than just CSPGs, axonal regrowth may be improved if the expression of specific, highly inhibitory CSPGs produced after injury were attenuated selectively. Neurocan is one type of CSPG …
Astroglial Boundary Formation And Epha4 Signaling In Neuroblast Migration, Nicholas B. Gallo
Astroglial Boundary Formation And Epha4 Signaling In Neuroblast Migration, Nicholas B. Gallo
University Scholar Projects
Adult neurogenesis, the process of generating new neurons from neural precursors, is a highly complex process that is limited to two specific areas of the brain, the dentate gyrus of the hippocampus and the subventricular zone (SVZ). Despite continued research investigating neurogenesis in these two regions, we still lack a fundamental understanding of the molecular mechanisms of neural cell division, migration, differentiation, and integration in the postnatal brain. In particular, the rostral migratory stream (RMS), which is a cellular migratory route for newly generated neuronal precursors that travel from the SVZ to the olfactory bulb, will provide a useful model …
