Book Description
Dans ce travail, nous avons étudié comment est-ce que les contacts cellules-cellules influencent la sécrétion d'insuline des cellules [beta]-pancréatiques. Cette étude nous a permis de mettre en évidence le double rôle des contacts intercellulaires dans la régulation de la sécrétion d'insuline puisque les cellules privées de contacts entre elles présentent une sécrétion basale trop élevée ainsi qu'une sécrétion stimulée trop faible en comparaison des cellules en contact les unes avec les autres. Nous montrons que les contacts physiques intercellulaires permettent de maintenir un niveau de calcium cytosolique stable, ce qui est indispensable pour une sécrétion basale adéquate et que, plus spécifiquement, l'engagement des molécules d'adhésion E-cadhérine entre cellules adjacentes permet d'optimiser la sécrétion d'insuline suite à une stimulation au glucose. Finalement, nous montrons que les cellules isolées restent capables de répondre au glucose une fois que leur sécrétion basale a été normalisée.

Book Description
Diabetes mellitus is rapidly increasing in prevalence throughout both developed and developing countries. The social and economic burden of this disease is estimated to cost 14 billion dollars worldwide. In the USA alone, 15 million individuals are diabetic, nearly half of them unaware of their condition. Complications of diabetes mellitus are the leading causes for blindness, limb amputation and chronic renal failure and kidney transplantation in industrialized countries. Further, diabetes mellitus per se and the metabolic derangement associated with diabetes are important risk factors for cardiovascular disease. Diabetes, as defined by an elevated fasting blood glucose level is presently subdivided in etiologically distinct groups. The most prevalent being type 2 (adult onset) diabetes characterized by insulin resistance and failure of the ~-cell to supply insulin in amounts sufficient to meet the body's needs. Type 1 (juvenile) diabetes, most commonly with an onset during childhood and adolescence, is caused by an auto-immune destruction of the pancreatic ~-cells. The causations of both type 1 and type 2 diabetes involve a combination of complex genetic traits and environmental influences. A third category are the mature onset diabetes of the young (MODY). This comparatively small group of patients (-10% of diabetes) presents relative early in life «30 years of age) compared to the more common late onset type 2 diabetes.

Mechanisms of Insulin Action

Mechanisms of Insulin Action PDF Author: Alan R. Saltiel
Publisher: Springer Science & Business Media
ISBN: 0387722041
Category : Medical
Languages : en
Pages : 223

Book Description
More than 18 million people in the United States have diabetes mellitus, and about 90% of these have the type 2 form of the disease. This book attempts to dissect the complexity of the molecular mechanisms of insulin action with a special emphasis on those features of the system that are subject to alteration in type 2 diabetes and other insulin resistant states. It explores insulin action at the most basic levels, through complex systems.

International Textbook of Diabetes Mellitus

International Textbook of Diabetes Mellitus PDF Author: R. A. DeFronzo
Publisher: John Wiley & Sons
ISBN: 1118387678
Category : Medical
Languages : en
Pages : 1200

Book Description
The International Textbook of Diabetes Mellitus has been a successful, well-respected medical textbook for almost 20 years, over 3 editions. Encyclopaedic and international in scope, the textbook covers all aspects of diabetes ensuring a truly multidisciplinary and global approach. Sections covered include epidemiology, diagnosis, pathogenesis, management and complications of diabetes and public health issues worldwide. It incorporates a vast amount of new data regarding the scientific understanding and clinical management of this disease, with each new edition always reflecting the substantial advances in the field. Whereas other diabetes textbooks are primarily clinical with less focus on the basic science behind diabetes, ITDM's primary philosophy has always been to comprehensively cover the basic science of metabolism, linking this closely to the pathophysiology and clinical aspects of the disease. Edited by four world-famous diabetes specialists, the book is divided into 13 sections, each section edited by a section editor of major international prominence. As well as covering all aspects of diabetes, from epidemiology and pathophysiology to the management of the condition and the complications that arise, this fourth edition also includes two new sections on NAFLD, NASH and non-traditional associations with diabetes, and clinical trial evidence in diabetes. This fourth edition of an internationally recognised textbook will once again provide all those involved in diabetes research and development, as well as diabetes specialists with the most comprehensive scientific reference book on diabetes available.

Cellular Endocrinology in Health and Disease

Cellular Endocrinology in Health and Disease PDF Author: Alfredo Ulloa-Aguirre
Publisher: Elsevier
ISBN: 0124167128
Category : Medical
Languages : en
Pages : 416

Book Description
Cellular Endocrinology in Health and Disease describes the underlying basis of endocrine function, providing an important tool to understand the fundamentals of endocrine diseases. Delivering a comprehensive review of the basic science of endocrinology, from cell biology to human disease, this work explores and dissects the function of a number of cellular systems. Among these are those whose function was not obvious until recently, including the endocrine functions of bone and the adipose tissue. Providing content that crosses disciplines, Cellular Endocrinology in Health and Disease details how cellular endocrine function contributes to system physiology and mediates endocrine disorders. A methods section proves novel and useful approaches across research focus that will be attractive to medical students, residents, and specialists in the field of endocrinology, as well as to those interested in cellular regulation. Editors Alfredo Ulloa-Aguirre and P. Michael Conn, experts in molecular and cellular aspects of endocrinology, deliver contributions carefully selected for relevance, impact, and clarity of expression from leading field experts. - Covers systemic endocrine action at the cellular level in both health and disease - Delivers information on the integration of cell identity and endocrinology - Incorporates recent developments in endocrinology to provide an up-to-date reference to researchers
