Available in PDF, EPUB and Kindle. Book excerpt: Glaucoma is one of the main causes of blindness throughout the world. It is characterized by death of the retinal ganglion cells, which is associated with loss of the axons making up the optic nerve. Recent studies have demonstrated support for the classification of glaucoma as a degenerative disease of the central nervous system (CNS), leading researchers to look at identifying neuroprotection strategies for the treatment of this disease, like those used for other degenerative diseases of the CNS. This book will provide an in-depth examination of the most recent findings regarding glaucoma, including risk factors, diagnosis, clinical monitoring, treatment, and above all, the need for treatment based on the concept of neuroprotection. A large part of the book is devoted to research related to this new approach to the treatment of glaucoma. - Describes the most recent developments on neuroprotection of the optic nerve, including experimental models now used and clinical protocols - Discusses new strategies for the prevention of neuronal injury in glaucoma patients - Focuses on evidence-based risk factors, innovative diagnostic aspects and advanced medical/surgical treatment of glaucoma

Abstract: In order to understand the possible mechanisms in the glaucoma-related retinopathy, the role of the vasoconstrictor, endothelin-1 (ET-1), receptor for advanced glycation end-products (RAGE) as well as its ligand, Aβ in the degeneration of retinal ganglion cells (RGCs) were studied in experimental models. In addition, the relationship of ET-1, RAGE and Aβ for the RGC protective mechanism of Lycium Barbarum (LB) was also investigated. In the first part, ET-1 together with its receptors, ETA and ETB, were studied to understand their possible roles in chronic ocular hypertension (COH). The neuronal protective mechanism of LB was also determined by using a well established COH rat model. In normal rats, ET-1 and its receptors, ETA and ETB, were distributed in the retina, vasculature and optic nerve. Interestingly, ET-1 expression was up-regulated after COH. LB could decrease the expression of ET-1 and regulate its receptors (up-regulation of ETB and down-regulation of ETA in vasculature; up-regulation of ETA and down-regulation of ETB in RGCs) under the condition of COH. These data suggested that the RGC protective mechanism of LB might be related to its ability to regulate the biological effects of ET-1. To investigate the pathogenic effect of ET-1 in glaucoma, in the second part, we used transgenic mice with over-expression of ET-1 on endothelial cells (TET-1 mice). We found that beginning at 10-12 months, TET-1 mice showed a progressive retinal degeneration (loss of RGCs associated with neurons in the inner nuclear layer and outer nuclear layer of the retina) without elevation of the intraocular pressure (IOP). The data demonstrated that TET-1 mice may serve as a potential model to investigate the role of endothelial ET-1 in the pathogenesis of normal tension glaucoma and other degenerative retinopathy. To investigate whether LB plays a role on neuronal protection other than in COH, in the third part, we used an acute ocular hypertension (AOH)-induced ischemia mouse model. We found that LB could rescue RGCs under AOH insult, associating with blood vessel protection (decreasing the damage of blood-retinal-barriers and rescuing the survival of endothelial cells and pericytes) and inhibiting retinal gliosis. We also found the protective mechanism of LB was closely correlated with down-regulation of the expression of RAGE, ET-1, APP (amyloid precursor protein), AGE (advanced glycation end-product) as well as Aβ; therefore to reduce the damage effects of these RAGE-mediated reactions to the retinal neurons, blood vessels and glial cells involved in the ischemic insult. Taken together, the present study demonstrated that TET-1 mice may be a potential model for investigating the role of ET-1 in degenerative retinopathies, such as normal tension glaucoma. We also showed the neuronal protective mechanism of LB in vivo was associated with inhibiting the biological effect of ET-1 and down-regulating the damage signaling pathways mediated by the activation of RAGE and its ligands (AGE and Aβ). These results provided further understandings in the mechanism of the glaucoma-related retinopathy. In addition, LB could be a neuroprotective agent to the retina following both chronic and acute injuries.

Download or read book Tau oligomers written by Jesus Avila and published by Frontiers E-books. This book was released on 2014-08-18 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neurofibrillary tangles (NFTs) composed of intracellular aggregates of tau protein are a key neuropathological feature of Alzheimer’s Disease (AD) and other neurodegenerative diseases, collectively termed tauopathies. The abundance of NFTs has been reported to correlate positively with the severity of cognitive impairment in AD. However, accumulating evidences derived from studies of experimental models have identified that NFTs themselves may not be neurotoxic. Now, many of tau researchers are seeking a “toxic” form of tau protein. Moreover, it was suggested that a “toxic” tau was capable to seed aggregation of native tau protein and to propagate in a prion-like manner. However, the exact neurotoxic tau species remain unclear. Because mature tangles seem to be non-toxic component, “tau oligomers” as the candidate of “toxic” tau have been investigated for more than one decade. In this topic, we will discuss our consensus of “tau oligomers” because the term of “tau oligomers” [e.g. dimer (disulfide bond-dependent or independent), multimer (more than dimer), granular (definition by EM or AFM) and maybe small filamentous aggregates] has been used by each researchers definition. From a biochemical point of view, tau protein has several unique characteristics such as natively unfolded conformation, thermo-stability, acid-stability, and capability of post-translational modifications. Although tau protein research has been continued for a long time, we are still missing the mechanisms of NFT formation. It is unclear how the conversion is occurred from natively unfolded protein to abnormally mis-folded protein. It remains unknown how tau protein can be formed filaments [e.g. paired helical filament (PHF), straight filament and twisted filament] in cells albeit in vitro studies confirmed tau self-assembly by several inducing factors. Researchers are still debating whether tau oligomerization is primary event rather than tau phosphorylation in the tau pathogenesis. Inhibition of either tau phosphorylation or aggregation has been investigated for the prevention of tauopathies, however, it will make an irrelevant result if we don’t know an exact target of neurotoxicity. It is a time to have a consensus of definition, terminology and methodology for the identification of “tau oligomers”.

Download or read book OCT and Imaging in Central Nervous System Diseases written by and published by . This book was released on 2020 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of OCT and Imaging in Central Nervous System Diseases offers updated state-of-the-art advances using optical coherence tomography (OCT) regrading neuronal loss within the retina. Detailed information on the OCT imaging and interpretation is provided for the evaluation of disease progression in numerous neurodegenerative disorders and as a biological marker of neuroaxonal injury. Covering disorders like multiple sclerosis, Parkinson's disease, Alzheimer's disease, intracranial hypertension, Friedreich's ataxia, schizophrenia, hereditary optic neuropathies, glaucoma, and amblyopia, readers will given insights into effects on the retina and the and optic nerve. Individual chapters are also devoted to OCT technique, new OCT technology in neuro-ophthalmology, OCT and pharmacological treatment, and the use of OCT in animal models. Similar to the first edition, this book is an excellent and richly illustrated reference for diagnosis of many retinal diseases and monitoring of surgical and medical treatment. OCT allows to study vision from of the retina to the optic tracts. Retinal axons in the retinal nerve fiber layer (RNFL) are non-myelinated until they penetrate the lamina cribrosa. Hence, the RNFL is an ideal structure for visualization of any process of neurodegeneration, neuroprotection, or regeneration. By documenting the ability of OCT to provide key information on CNS diseases, this book illustrates convincingly that the eye is indeed the "window to the brain".
