Sphingolipids are lipid components of the plasma membrane of eukaryotic cells with an important function in signaling mechanisms in the cell. This book provides insight into the physiological and pathophysiological role of sphingolipids and in particular its derivative ceramide. The function of Sphingolipids in cell signaling with regard to infectious and lung diseases, cancer, cardiovascular diseases and neuropsychiatric disorders are described and treated in distinct parts. Together with Volume 215 from the same Editors, the collection represents a unique, comprehensive work on Sphingolipids, providing information on both: Sphingolipid basic biology as well as its important function in a (patho)physiological context. The book is written for scientists in pharmacology, biochemistry and cell biology with a focus on biomedical research as well as for clinicians in pharmacology, oncology, cardiology, neurology and infectious disease. ​

Current thinking holds that obesity derives primarily from overnutrition (though compelling arguments for other mechanisms, like endocrine disruption by environmental pollutants, also gain support from the literature). In animals, overnutrition is initially handled by adipose tissue expansion; however, exhaustion of this route of lipid sequestering results in oversupply of lipid to other tissues including skeletal muscle, heart, liver, and others. Failure of these tissues to clear excess lipids through either metabolism or sequestration into putatively inert triacylglycerols results in perturbation of bioactive lipid metabolism in cells. In particular, aberrant generation of bioactive sphingolipids is implicated in a multitude of pathological outcomes of metabolic disease including insulin resistance, inflammation, cardiomyopathy, and others. This volume addresses not only the fundamentals of sphingolipid metabolism and analysis, but also the roles of sphingolipids in these disease processes.

This text contains the scientific contributions to the Fourth International Symposium on Sphingolipids, Sphingo lipidoses and Allied Disorders held at the Kingsbrook Jewish Medical Center on October 25-27, 1971. These meetings were conducted under the auspices of the Isaac Albert Research Institute of the Kingsbrook Jewish Medical Center and the National Tay-Sachs and Allied Diseases Association, Inc. Four symposia, held in 1958, 1961, 1965 and 1971 were designed to gather the most relevant and innovative of the laboratory and field studies concerned with these hereditary disorders. The texts generated by these periodic meetings have mirrored the increasing absorption of the scientific community in the problems of sphingolipid metabolism. The first meeting in 1958 consisted of but twelve pre sentations, the majority emanating from local laboratories. The current sessions contain 48 scientific presentations by scientists from nine countries and demonstrate the increas ingly diversified techniques and approaches employed in the study of these diseases. Many of the authors, in exploring data on the mucopolysaccharidoses and leucodystrophies, as well as the sphingolipidoses, have given recognition to those biochemical areas held in common by these otherwise diverse disease processes. The problems of prevention and therapy of these diseases have been considered by some of the contributors. Laboratory screening procedures designed to detect carriers of the va rious lipidoses are now available and the experiences of some laboratories in this area are summarized within this volume. The prospective identification of heterozygotes may indeed become a powerful adjunct in genetic counseling.

Although sphingolipids are ubiquitous components of cellular membranes, their abundance in cells is generally lower than glycerolipids or cholesterol, representing less than 20% of total lipid mass. Following their discovery in the brain—which contains the largest amounts of sphingolipids in the body—and first description in 1884 by J.L.W. Thudichum, sphingolipids have been overlooked for almost a century, perhaps due to their complexity and enigmatic nature. When sphingolipidoses were discovered, a series of inherited diseases caused by enzyme mutations involved in sphingolipid degradation returned to the limelight. The essential breakthrough came decades later, in the 1990s, with the discovery that sphingolipids were not just structural elements of cellular membranes but intra- and extracellular signaling molecules. It turned out that their lipid backbones, including ceramide and sphingosine-1-phosphate, had selective physiological functions. Thus, sphingolipids emerged as essential players in several pathologies including cancer, diabetes, neurodegenerative disorders, and autoimmune diseases. The present volume reflects upon the unexpectedly eclectic functions of sphingolipids in health, disease, and therapy. This fascinating lipid class will continue to be the subject of up-and-coming future discoveries, especially with regard to new therapeutic strategies.

Sphingolipids are lipid components of the plasma membrane in eukaryotic cells. They have an important function in signaling mechanisms in the cell. This book on sphingolipids provides insights into the basics of sphingolipid biology and drug development, with a particular emphasis on the sphingolipid derivative ceramide. In the first part basic functions of sphingolipids are described, as well as the genetics of important enzymes, sphingolipid metabolism and synthesis. The second part of this first volume focuses on drug development and pharmacology. The book is intended for scientists in pharmacology, biochemistry and cell biology with a focus on biomedical research as well as for clinicians working in pharmacology, oncology, cardiology, neurology and infectious disease. Together with Volume 216 by the same editors, the collection represents a unique, comprehensive work on sphingolipids, providing information on both sphingolipids’ basic biology (including synthesis, metabolism and cell biology) and their important function in a (patho-)physiological context.

Even though initially considered as a passive means for storing energy, lipids are now regarded as multifaceted molecules with crucial structural and functional activities. For instance, some of them play essential roles as key components of cell membranes whereas others act as signaling molecules in the regulation of cell homeostasis. In recent years, lipid research has attracted increasing interest because of the involvement of this class of compounds in human health. Indeed, a plethora of pathological conditions are characterized by alterations in lipid metabolism, such as cardiovascular diseases and brain disorders. This Special Issue is a collection of papers from different experts in lipid research, with the aim of providing new insights into the physiopathological involvement of lipids and their impact on human health. This collection also demonstrates the usefulness of interdisciplinary approaches in the development of novel methods to study and manipulate lipid metabolism, which may represent an attractive target for designing effective therapeutic strategies to counteract numerous pathologies.
