Download or read book Studies on Retinal and Choroidal Disorders written by Robert D. Stratton and published by Springer Science & Business Media. This book was released on 2012-02-17 with total page 644 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies on Retinal and Choroidal Disorders examines the role that oxidative and nitrosative stress plays in the complex physiology and pathophysiology of the retina and choroid. Both the basic science researcher and the clinical practitioner can use this book as a guide to the current understanding of retinal and choroidal cellular mechanisms involved in aging and disease. Beginning with a review of oxidative stress and inflammation in the pathoetiology of AMD and a review of the complement system in the retina, the book then takes a detailed look at oxidative stress in lipid metabolism and oxidized lipoproteins in the retina. It examines the anti-apoptotic activity of α-crystallins in the presence of glutathione, oxidative stress in the mitochondria and endoplasmic reticulum, the role of iron in retinal disease, the mechanisms of pathological VEGF expression, NAPDH oxidase mechanisms, and Hepatocyte Growth Factor in oxidative stress in the retina. A detailed look at the Ccl2-/-/Cx3cr1-/- mouse model of AMD follows. Then a detailed examination of the systemic changes in AMD is followed by a discussion of cerium oxide nanoparticle reduction of oxidative stress. Two chapters discuss progenitor cells in the cause and treatment of retinal diseases including AMD and diabetic retinopathy. Natural compounds in the prevention and treatment of retinal diseases are exhaustively presented, followed by a chapter on serotonin 5-HT1A receptor agonists in oxidative stress of the retina. The current anti-VEGF treatment strategies of neovascular AMD are then given. The volume continues with a detailed look at nitric oxide and inducible nitric oxide synthase in retinal vascular disease, an explanation of an in vivo technique of studying the effect of lipid hydroperoxides on circulating leucocytes in the retina, an excellent review of oxidative stress in retinopathy of prematurity, and a look at VEGF induced oxidative stress in the retinal ganglion cell. The book ends with a detail examination of the role of carotenoids in retinal health and disease. These 31 chapters summarize what is known about oxidative stress in retinal and choroidal disorders. All those involved with degenerative diseases of the eye will find Studies on Retinal and Choroidal Disorders to be illuminating and comprehensive.

Author :Francesco Bandello Publisher :Karger Medical and Scientific Publishers ISBN 13 :3805595298 Total Pages :155 pages Book Rating :4.8/5 (55 download)
Download or read book Anti-VEGF written by Francesco Bandello and published by Karger Medical and Scientific Publishers. This book was released on 2010-01-01 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of therapy with anti-angiogenics or vascular endothelial growth factor inhibitors (anti-VEGF) has marked the beginning of a new era in neovascularization and macular edema treatment. Its main goals are the inhibition of growth and development of new vessels along with the reduction of vascular permeability. The advantages over conventional laser photocoagulation are evident as laser treatment always leaves scars and causes a retinal sensitivity deterioration. Starting with an outline of treatment principles, this volume covers all aspects of anti-VEGF therapy for ophthalmological disorders. In particular, specific chapters are dedicated to age-related macular degeneration, degenerative myopia, angioid streaks, inflammatory diseases, hereditary dystrophies, retinal vein occlusion, diabetic retinopathy, ocular tumors, as well as anterior segment neovascularization. The book gives an update on the application of anti-VEGF in ocular diseases to general ophthalmologists as well as retina specialists.

Book Synopsis Investigating mechanisms of angiogenesis in health and disease using zebrafish models by : Zaheer Ali
Download or read book Investigating mechanisms of angiogenesis in health and disease using zebrafish models written by Zaheer Ali and published by Linköping University Electronic Press. This book was released on 2018-12-07 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: Angiogenesis, the growth of blood vessels from an existing vasculature, can occur by sprouting from preexisting vessels or by vessel splitting (intussusception). Pathological angiogenesis drives choroidal neovascularization (CNV) in age related macular degeneration (AMD) which is commonly restricted under the retinal pigment epithelium (RPE), called occult CNV, but may also involve vessels penetrating through the RPE into the sub-retinal space. Pathological vessels are poorly developed, insufficiently perfused and highly leaky, phenotypes that are considered to drive disease progression and lead to poor prognosis. Currently, a number of anti-angiogenic drugs exists, the majority of which target vascular endothelial factor (VEGF), but although they often are highly beneficial for treating eye diseases in the short-term, they are generally of limited efficacy in other diseases such as cancer, and also have poorer efficacy when used for treatment of eye diseases in the long-term. A better understanding of the mechanisms underlying pathological angiogenesis can generate new targets for treatment leading to development of better drugs for cancer and retinopathies, but perhaps also other angiogenesis-dependent diseases, in the future. In this thesis mechanisms involved in developmental angiogenesis or pathological angiogenesis in the choroid, cornea or melanoma was identified. These findings highlight the need to further elaborate our knowledge related to angiogenesis in different tissues/conditions for a more targeted, and potentially effective treatment of diseases in the future. In paper I, we for the first time identified the choriocapillaries (CCs) in adult zebrafish and found that occult CNV could be induced by exposing the fish to severe hypoxia. Interestingly, we found that occult CNV relied on intussusception, involving not only de novo generation of intussusceptive pillars but also a previously poorly understood mechanism called pillar splitting. This involved HIF-VEGF-VEGFR2 signaling and evidence that this also occurred in both rats and humans suffering from AMD suggested that the mechanism was conserved and clinically relevant. In contrast, we found in paper II that the development of CCs in the zebrafish relies on sprouting angiogenesis, involve continuous remodeling, and delayed maturation of the vasculature in 2D. The initial development was found to occur by a unique process of tissuewide synchronized vasculogenesis. As expected, VEGFA via VEGFR2 was also critical for the development of these vessels in the zebrafish embryo, but surprisingly this was independent on hypoxia-inducible factor (HIF)-1. Inflammatory nuclear factor-kB (NF-kB) signaling is involved in the progression of angiogenesis, but this signaling pathway has mainly been studied in the inflammatory cells and the role of NF-kB in the endothelial cells during angiogenesis is poorly understood. In paper III, we found that blocking NF-kB signaling using a specific IKK2 blocker IMD0354, specifically blocks pathological as well as developmental angiogenesis by targeting endothelial cell NF-kB signaling in the endothelial cells. Using a rat model for suture-induced corneal neovascularization, IMD0354 treatment lead to reduced production of inflammatory C-C motif chemokine ligand 2 (CCL2), C-X-C motif chemokine ligand 5 (CXCL5) and VEGF, and thereby reduced pathological corneal angiogenesis in this model. Using the zebrafish tumor xenograft model in paper IV, we found an association between Microphthalmia associated transcription factor (MITF) and pigment epithelium derived factor (PEDF), which was involved in pathological tumor angiogenesis and metastasis. Similarly, in paper V we used zebrafish transplantation models to study and investigate the use of biocompatible polymers for the delivery of pro-angiogenic FGF-2 as a potential treatment strategy for ischemic diseases such as myocardial infarction (MI). Conclusively, this thesis provides new insights into diverse fields of angiogenic assays using zebrafish, and reveals new mechanisms of angiogenesis in health and disease. This work will hopefully provide a foundation for further studies into occult CNV related to AMD, a process that has not been possible to study previously in pre-clinical models. In addition, zebrafish xenograft or other transplantation models used in this work will likely be important to study cancer biology and to develop more attractive pharmaceutical preparations based on biocompatible hydrogels formulated as microspheres in the future.
