Cholesterol levels have been repeatedly linked to Alzheimer's Disease (AD), suggesting that high levels could be detrimental, but this effect is likely attributed to Low-Density Lipoprotein (LDL) cholesterol. On the other hand, High-Density Lipoproteins (HDL) cholesterol levels have been associated with reduced brain amyloidosis and improved cognitive function. However, recent findings have suggested that HDL-functionality, which depends upon the HDL-cargo proteins associated with HDL, rather than HDL levels, appears to be the key factor, suggesting a quality over quantity status. In this report, we have assessed the HDL-cargo (Cholesterol, ApoA-I, ApoA-II, ApoC-I, ApoC-III, ApoD, ApoE, ApoH, ApoJ, CRP, and SAA) …
Qki-Mediated Cholesterol Biosynthesis In Eye Lens And Myelin Of The Central Nervous System, Seula Shin, Seula Shin
Qki-Mediated Cholesterol Biosynthesis In Eye Lens And Myelin Of The Central Nervous System, Seula Shin, Seula Shin
Dissertations & Theses (Open Access)
Cells obtain cholesterol in two ways, de novo biosynthesis and uptake from circulation. While most tissues utilize both sources, eye lens and brain depend extensively on cholesterol biosynthesis due to the limited supply from circulation. Lens cell membrane consists of highest portion of cholesterol. Brain is the most cholesterol-rich organ, which accounts for 23% of total cholesterol. Genetic mutations of cholesterol biosynthesis enzymes in humans and animal models present cataracts and hypomyelinating disorders linked to neurological impairment. Yet, it remains unclear how gene expression of cholesterol biosynthesis is regulated in lens and brain. Therefore, studying cholesterol biosynthesis in both tissues …

Oxysterols are important for cholesterol homeostasis in the brain and may be affected in neurodegenerative diseases. The levels of the brain-derived oxysterol 24S-hydroxycholesterol (24S-OH) have been reported to be markedly reduced in the circulation of patients with Parkinson's disease (PD) (Lee et al., Antioxid. Redox Signal. 11 (2009) 407–420). The finding is surprising in view of the fact that other neurodegenerative diseases are associated with relatively modest effects on the circulating levels of 24S-OH. We determined the plasma and cerebrospinal fluid (CSF) levels of 24S-OH and 27-hydroxycholesterol (27-OH) in patients with PD with different disease duration using a highly accurate …
Bi-Lateral Changes To Hippocampal Cholesterol Levels During Epileptogenesis And In Chronic Epilepsy Following Focal-Onset Status Epilepticus In Mice, Steve Meaney, Maura Heverin, Tobias Engel, Eva Jimenez-Mateosa, Reza Al-Aaudia, David Henshall

Brain cholesterol homeostasis has been shown to be disrupted in neurodegenerative conditions such as Alzheimer's and Huntington's diseases. Investigations in animal models of seizure-induced brain injury suggest that brain cholesterol levels are altered by prolonged seizures (status epilepticus) and are a feature of the pathophysiology of temporal lobe epilepsy. The present study measured hippocampal sterol levels in a model of unilateral hippocampal injury triggered by focal-onset status epilepticus, and in chronically epileptic mice. Status epilepticus was induced by intra-amygdala microinjection of kainic acid and ipsilateral and contralateral hippocampus analyzed. No significant changes were found for ipsilateral or contralateral hippocampal levels …
Investigating The Impact Of Cd147 And Its Expression On Neurodegenaration And Alzheimer's Disease (Ad), Limbikani J. Kanyenda
Investigating The Impact Of Cd147 And Its Expression On Neurodegenaration And Alzheimer's Disease (Ad), Limbikani J. Kanyenda
Theses: Doctorates and Masters
CD147, also known as basigin, extracellular matrix metalloproteinase inducer, neurothelin, tumour cell-derived collagenase stimulatory factor, M6, HT7, OX47 or gp42, is a transmembrane glycoprotein of the immunoglobulin super-family. It is expressed in many neuronal and non-neuronal tissues with high expression in the hippocampus, pre-frontal cortex, thyroid, heart, early erythroid, amygdala and placenta. This protein is involved in various cellular and biological functions such as lymphocyte migration and maturation, tissue repair, cancer progression, T and B lymphocyte activation and induction of extracellular matrix metalloproteinase. The CD147 protein interacts with with cyclophilin A, cyclophilin B, sterol carrier protein, caveolin-1 and integrins, and …
Wernekink Comissure Syndrome: A Rare Midbrain Syndrome Secondary To Stroke, Alper I. Dai, Mohammad Wasay
Wernekink Comissure Syndrome: A Rare Midbrain Syndrome Secondary To Stroke, Alper I. Dai, Mohammad Wasay
Department of Medicine
Wernekink commissure involves the decussation of superior cerebellar peduncle (SCP) in midbrain. We report an elderly hypertensive, diabetic man who developed slurred speech, ataxia, and internuclear ophthalmoplegia. MRI examination revealed an unusual ischemic stroke involving Wernekink commissure. This rare stroke pattern involving decussation of SCP occurs in the setting of small arterial disease. The association between the anatomic location of the stroke and clinical findings is noteworthy.
