Signal Transduction in the Retina Book Excerpt:

In the twenty-first century, we are just beginning to understand more clearly the enormous diversity and complexity of signaling processes in the retina. Integrating advances in the biochemistry, cell biology, physiology, and physics of phototransduction, Signal Transduction in the Retina presents the methodologies and experimental approaches that yield key information on the mechanisms underlying normal retinal physiology. This in-depth work discusses the latest techniques and applications for understanding retinal function and degradation, developing novel therapeutic strategies, and promoting cellular survival and functional retention. Drawing contributions from experts in a range of disciplines, each chapter presents a brief overview of the area discussed along with specific methodology for obtaining the primary data to understand the cellular and molecular process. Given the dominance and wealth of information on rhodopsin-based phototransduction, the book devotes substantial attention to this topic, but also evaluates a diversity of signaling mechanisms. Beginning with the molecular mechanisms of vertebrate phototransduction, this volume presents the structure of phototransduction cascade components at atomic resolution, as well as molecular interactions in multi-protein complexes and novel cell-based strategies for understanding signal shut-off and light adaptation. It discusses non-visual phototransduction and the role of melanopsin in adaptive photoresponses and circadian clock regulation. The book also compares the visual signaling processes of vertebrates and invertebrates. It examines experimental studies of insulin-based signaling in the inner and outer retina; investigates retinal development including signaling in progenitor cells, cell-cell communication in developing cells, and neovascularization; and studies lipid-derived mediators such as neuroprotectins and discusses the participation of retinal pigment epithelium in neuronal survival.

Neurobiology and Clinical Aspects of the Outer Retina Book Excerpt:

This book deals with the cellular biology, biochemistry and physiology of photoreceptors and their interactions with the second-order neurons, bipolar and horizontal cells. The focus is upon the contributions made by these neurons to vision. Thus the basic neurobiology of the outer retina is related to the visual process, and visual defects that could arise from abnormalities in this part of the retina are highlighted in the first 16 chapters. Since all vertebrate retinas have the same basic structure and physiological plan, examples are given from a variety of species, with an emphasis upon mammals, extending to human vision. The last four chapters approach the problem from the other end. This part of the book covers a range of clinical conditions involving visual abnormalities that are due to cellular defects in the outer retina. Although the contents of this book do not represent the proceedings of a conference, the concept arose at an international symposium on 'Recent Advances in Retinal Research' which was held at the International Marine Centre in Oristano, Sardinia. We hope that the book will give a coherent, up to date review of the neurobiology and clinical aspects of the outer retina and encourage further integration of these areas. Retinal neurobiology has been an intense field of investigation for several decades. More recently, it has seen significant advances with the application of modern techniques of cell and molecular biology.

Postnatal Development of the Cat s Retina Book Excerpt:

References ............................................... 59 Subject Index ............................................. 65 6 Introduction The retina as an organ of perception of light, colour, shape and movement has been the subject of numerous and intensive light- and electron-microscopical investigations. To date the interest in these has largely been concentrated on the structure of the ma ture retina and the genesis of its cellular elements. The first exhaustive observations on the development of the retina in vertebrates were made by Babuchin (1863). Using the retinae of chicken embryos, he showed that Millier's radial fibres and the ganglion cells are the first to develop, while the receptor segments are the last. Subsequently, the early differentiation of Millier's radial fibres was often reaffirmed (Cajal, 1893; Meller, 1968; Bhattacharjee and Sanyal, 1975; and others). Furthermore, Babuchin had already indicated that the structural development in the area of the posterior pole is very rapid compared with those regions of the retina which are situated more peripherally. Today, when comparing results of electron-mi croscopical investigations, this fact is of particular importance, since in each case only very limited areas of the retina can be examined. Schultze (1867a, b) pointed out the uniformity of origin and the general classifica tion of light-perceiving elements into inner and outer segments, thus contesting the hitherto generally held opinion that these structures, like the pigment epithelium, ori of the eye cup. In 1881 Ogneff discovered the analogous ginate from the outer leaf mode of formation in birds and mammals.

The Retina and Circadian Rhythms Book Excerpt:

Daily rhythms are a ubiquitous feature of living systems. Generally, these rhythms are not just passive consequences of cyclic fluctuations in the environment, but instead originate within the organism. In mammals, including humans, the master pacemaker controlling 24-hour rhythms is localized in the suprachiasmatic nuclei of the hypothalamus (SCN). This circadian clock is responsible for the temporal organization of a wide variety of functions, ranging from sleep and food intake, to physiological measures such as body temperature, heart rate and hormone release. Moreover, accumulating evidence suggests that dysfunction of the circadian rhythms due to genetic mutations or environmental factors (i.e., jet-lag or shift work) contribute to the development of many pathologies, including sleep disorders, mood and affective disorders such as major depression, bipolar disorder and schizophrenia, as well as the risk of metabolic and cardiovascular disorders.

Neurobiology of the Inner Retina Book Excerpt:

The relatively simple, stratified nature of the retina and its spe- fied use in the visual process has long made it an inviting tissue to study both for its own sake and as a model for the more complex processes of the brain. For these dual purposes, the retina can be thought of as basically consisting of two functional pans. First, the outer retina, comprised of the photoreceptor cells and attendant pigment epithelium, serves to capture the photic energy and convert it into a neurochemical response. Second, the inner layers of the retina, mainly bipolar, amacrine and ganglion cells (and their attendant Maller cells), function more clearly as a typical part of the CNS, transmitting the photic signals to the brain. Between the 8th and 12th of August 1988 more than seventy scientists from allover the world gathered in Oldenburg (Federal Republic of Gennany) for a meeting "The neurobiology of the inner retina" which was devoted entirely to the neural mechanism of the inner synaptic layer of the verte brate retina. The meeting comprised twenty - three separate lectures and four specially arranged discussion groups. In addition, a number of posters were displayed and a period was allotted specifically for the discussion of these posters. The articles contained in this book will serve as a record of the papers delivered at the Oldenburg Meeting and illustrate the advances made in trying to understand the importance of the diversity of amacrine cell morphology and physiology in retinal function.

Molecular Mechanisms of Retina Pathology and Ways of its Correction Book Excerpt:

This book discusses the pathology of the retina, and reviews current research on the use of cell replacement therapy and short peptides to restore functional activity in retinal neurons. As the book describes, pathologies of the retina, including age-related macular degeneration, diabetic retinopathy, and retinitis pigmentosa, present a long-standing challenge in the practice of clinical ophthalmology. Modern treatment for these conditions, which lead to irreversible blindness, includes laser exposure, surgical intervention, and drugs. These treatments aim to reduce the risk of new complications in the eye; pathogenetic therapy of degenerative diseases of the retina is practically absent in current ophthalmic practice. The first section of the book reviews the molecular mechanisms of age-related macular degeneration, diabetic retinopathy, and retinitis pigmentosa, and reports on methods of treatment. The second section presents the results of recent experimental studies of the effects of short peptides on pluripotent embryonic cells; on proliferative activity in retinal cells and pigment epithelium; on expression of markers of differentiation or retinal neurons and pigment epithelium; and on the course of hereditary retinal pigmentation in Campbell rats. The third section offers results of clinical studies on the effectiveness of short peptides in patients with macular degeneration, and in patients with retinitis pigmentosa. The author concludes that the regular use of peptides in the treatment of degenerative diseases of the retina can slow the progression of the pathological process and preserve the patient’s vision for some 10-15 years. In addition, in 80 percent of patients, it is possible to increase visual function by increasing visual acuity, improving the boundaries of the visual field and the fundus.
