Abstract

En transplantation humaine, l’utilisation d’immunosuppresseurs tels que la cyclosporine A ou plus récemment le FK506, a permis une augmentation significative du taux de réussite des allogreffes. Ces succès ont favorisés l’accroissement et la diversification des allogreffes au point que, actuellement, le facteur limitant n’est plus la difficulté de l’acte technique ou le traitement immunosuppresseurs, mais bien la disponibilité d’organes (Hardy et coll., 1984). En effet, actuellement la demande d’organes dépasse largement l’offre et face à ce déficit croissant, une alternative potentielle est apparue : la réalisation des xénogreffes, c’est-à-dire l’utilisation d’organes provenant d’une espèce différente de celle du receveur. Le domaine des xénogreffes suscite un vif intérêt dans de nombreuses équipes des Cliniques universitaires Saint-Luc et de la Faculté de médecine de l’UCL dont le Laboratoire d’immunologie expérimentale du Prof. H. Bazin. Au sein de ce laboratoire, nous nous sommes proposé d’étudier les mécanismes immunologiques pouvant expliquer le rejet des xénogreffes discordantes.

Abstract

Natural antibodies (NAbs) are found in normal individuals in the absence of exogenous antigenic stimulation. Natural antibodies rapidly recognize and protect against pathogens that have not been previously encountered. NAbs also cross-react with several self-antigens, which, besides their role as a first line of defense against pathogens, affords them the ability to perform important housekeeping functions in healthy organisms. Such housekeeping functions include the clearance of oxidized damaged structures and/or apoptotic cells, which prevents the induction of pro-inflammatory effects. In addition, NAbs play a role in preventing the expansion of specific auto-reactive clones, thereby behaving as regulatory elements in acute or chronic inflammation. To maintain the non-pathogenic balance between the dual pathogen/self-antigen cross-reactivities of NAbs, a strict regulation in NAb secretion and function is necessary to avoid autoimmune disease. Actually, some of the NAbs related auto-reactivities, such as anti-DNA and anti-MOG, have been associated with autoimmunity. Furthermore, NAbs have been shown to bind to ‘neo-self’ carbohydrate antigens on glycolipids and glycoproteins found on malignant but not normal cells, which suggests NAbs may take part in tumor immunosurveillance. Many aspects regarding NAbs have yet to be studied in more detail: the reactivity and function of NAbs in health and disease, the behavior of the NAb repertoire with increasing age, the regulation of natural antibody production and auto-reactivity, the ways to specifically activate NAbs producing cells with desired specificities, the characteristics of human NAbs, among others. This special topics eBook consists of a number of articles exploring the cells that produce NAbs as well as the characteristics, function, specificity, and/or the role of natural antibodies in health and disease.

Abstract

This volume reviews the current state of research on the IgM antibody and its multiple receptors and binding proteins. Interactions of the IgM ligands with these molecules are important for protection against infections as a first line of defense, as well as for regulation of immune responses to pathogens and self-antigens. The book includes up-to-date information on: (i) the phylogeny of three IgM-binding receptors [polymeric Ig receptor (pIgR), Fc receptor for both IgA and IgM (Fcα/µR), and Fc receptor for IgM only (FcµR)]; (ii) the lymphocyte-restricted distribution and unique ligand-binding activity of FcµR; (iii) the definition and potential function of Fc receptor-like molecule A (FCRLA) as a resident endoplasmic reticulum protein that binds IgM, but also IgG and IgA; (iv) IgM antibody-mediated enhancement of humoral immune responses, highlighting the importance of complement and its receptors, (v) the numerous important roles of IgM natural antibodies in regulation of inflammation. It is an invaluable resource for researchers and clinicians alike.

Abstract

Union of Parts examines one of the central puzzles in the economic and political successes of West Germany (FRG). In the decades between world war and reunification with the East, the FRG provided a model for combining high rates of unionization and substantial labor peace-indeed, for collaboration between organized labor and organized capital as both groups faced the dislocations involved in adjusting to a changing global marketplace.

Abstract

This book provides a comprehensive, self-contained introduction to one of the most exciting frontiers in astrophysics today: the quest to understand how the oldest and most distant galaxies in our universe first formed. Until now, most research on this question has been theoretical, but the next few years will bring about a new generation of large telescopes that promise to supply a flood of data about the infant universe during its first billion years after the big bang. This book bridges the gap between theory and observation. It is an invaluable reference for students and researchers on early galaxies. The First Galaxies in the Universe starts from basic physical principles before moving on to more advanced material. Topics include the gravitational growth of structure, the intergalactic medium, the formation and evolution of the first stars and black holes, feedback and galaxy evolution, reionization, 21-cm cosmology, and more. Provides a comprehensive introduction to this exciting frontier in astrophysics Begins from first principles Covers advanced topics such as the first stars and 21-cm cosmology Prepares students for research using the next generation of large telescopes Discusses many open questions to be explored in the coming decade
