Although neurodegenerative diseases are often clinically distinct, they typically share common pathological markers. One of the most common causes of clinical dementia is Alzheimer’s disease (AD). Pathologically, AD is defined by the presence of intercellular tangles composed of hyperphosphorylated tau proteins and extracellular plaques made of abnormally cleaved amyloid-beta proteins. However recent genome-wide association studies have also found that many of the predispositions for AD are located on or near genes highly expressed in microglia. In the healthy CNS, microglia act as the brain’s immune system and are chiefly involved in neuronal support and maintaining homeostasis throughout the CNS. Typically, …

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 …
Vascular Cognitive Impairment And Dementia: The Importance Of Mixed Pathologies From Mouse Models To Humans, Alex Marian Helman
Vascular Cognitive Impairment And Dementia: The Importance Of Mixed Pathologies From Mouse Models To Humans, Alex Marian Helman
Theses and Dissertations--Molecular and Cellular Biochemistry
Age-related neurologic disease is a significant and growing burden on our society. Although the largest share of research effort has typically been devoted to the common neurodegenerative illnesses (such as Alzheimer’s disease, or AD), the reality is that nearly all cases of neurodegenerative disease possess elements of mixed pathology. Vascular contributions to cognitive impairment and dementia (VCID) is a complex form of dementia, combining aspects of vascular disease and other forms of dementia, such as Alzheimer’s disease. This pathology is heterogeneous and can include cerebral amyloid angiopathy (CAA), hemorrhages, white matter infarcts, and changes to the neurovascular unit. Given the …

The Cellular Nucleic Acid Binding Protein In Aging And Disease, Robin Webb
Theses and Dissertations--Molecular and Cellular Biochemistry
The ZNF9 gene on chromosome 3 encodes the cellular nucleic acid binding protein (CNBP), a ubiquitously expressed, 177 amino acid (≈19.5kDa) protein that is highly conserved among vertebrates. The function of the protein is largely unknown, however an expansion in the first intron of the protein results in myotonic dystrophy type 2 (DM2), a multisystemic disease featuring cardiac arrhythmia, muscle wasting, cataracts, and a range of neuropathologies. Remarkably, we recently discovered that CNBP is involved in regulating the activity of β-secretase, the enzyme that produces the first cleavage event in the generation of the amyloid-β peptide (Aβ). The progressive fibrillization …
