Abstract

Quel est le lien entre immunologie et identité ? Au cœur de l’immunologie se trouvent les concepts de « soi » et de « non-soi », ainsi que ceux d’unicité et d’individualité. Les immunologistes contemporains affirment que, en se fondant sur le vocabulaire du soi et du non-soi, leur discipline apporte une réponse à la question de savoir ce qui fait l’identité d’un organisme à travers le temps. Cet ouvrage met en doute cette affirmation. S’appuyant sur des données récentes sur la tolérance immunitaire, le chimérisme ou encore la symbiose, il montre que la théorie du soi et du non-soi, qui domine l’immunologie depuis plus de cinquante ans, n’est plus adéquate. Il propose une autre théorie, la théorie de la continuité, dont l’un des objectifs est de rendre compte des nombreux cas dans lesquels un organisme tolère des entités étrangères, en particulier des bactéries. L’organisme doit alors être compris selon une perspective écologique : il est ouvert à l’extériorité, à l’autre, et en grande partie constitué par l’appropriation d’entités initialement « étrangères ». L’immunologie donne bien une définition de l’identité biologique, mais celle-ci est aux antipodes de la conception selon laquelle l’organisme serait une réalité fermée, définie de façon endogène et défendant son intégrité contre tout « non-soi ».

Abstract

This book focuses on the function of antibodies in vivo. Recent years have seen an exponential growth in knowledge about the molecular and cellular mechanisms of antibody activity. These new results dramatically changed our view of how antibodies function in vivo. The importance of this class of molecules is demonstrated by the heightened susceptibility to infections of humans and mice with an altered capacity to generate pathogen specific antibody responses. Thus, the majority of our currently available vaccines, such as vaccines against influenza, measles and hepatitis focus on the generation of long lasting antibody responses. Recent evidence from a variety of in vivo model systems and from human patient cohorts has highlighted the exclusive role of cellular Fc-receptors for certain immunoglobulin isotypes and subclasses. With the recent discovery of a human Fc-receptor for IgM all different human immunoglobulin isotypes now have a cellular receptor, providing a feedback mechanism and link between antibodies and the cellular components of the immune system. Moreover it has become clear the complement and Fc-receptor system are tightly connected and regulate each other to ensure a well balanced immune response. Among the immunoglobulin isotypes IgG plays a very important protective role against microbial infections and also as a therapeutic agent to kill tumor cells or autoantibody producing B cells in autoimmune disease. Transfer of our knowledge about the crucial function of Fc-receptors has led to the production of a second generation of therapeutic antibodies with enhanced binding to this class of receptors. Binding of antibodies to Fc-receptors leads to the recruitment of the potent pro-inflammatory effector functions of cells from the innate immune system. Hence, Fc-receptors link the innate and adaptive immune system, emphasizing the importance of both arms of the immune system and their crosstalk during anti-microbial immune responses. Besides this pro-inflammatory activity immunoglobulin G (IgG) molecules are long known to also have an anti-inflammatory function. This is demonstrated by the use of high dose intravenous immunoglobulins as a therapeutic agent in many human autoimmune diseases. During the past five years several new insights into the molecular and cellular pathways of this anti-inflammatory activity were gained radically changing our view of IgG function in vivo. Several lines of evidence suggest that the sugar moiety attached to the IgG molecule is responsible for these opposing activities and may be seen as a molecular switch enabling the immune system to change IgG function from a pro- to an anti-inflammatory activity. There is convincing evidence in mice and humans that aberrant IgG glycosylation could be an important new pathway for understanding the impaired antibody activity during autoimmune disease. Besides this tremendous increase in basic knowledge about factors influencing immunoglobulin activity the book will also provide insights into how these new insights might help to generate novel therapeutic approaches to enhance IgG activity for tumor therapy on the one hand, and how to block the self-destructive activity of IgG autoantibodies during autoimmune disease on the other hand.

Abstract

This book provides an essential overview of the role of phosphoinositide-3-phosphate kinase (PI3K) isoforms in modulating the function of immune system cells and their involvement in disease. PI3K is a family of kinases involved in basic cellular processes such as proliferation, migration and cell death. Recent work has highlighted the multiple roles of PI3K classes and subunits and their involvement in the immune response to the body’s own and foreign antigens and diseases such as cancer and autoimmunity. This book offers a detailed introduction to the biology of the three PI3K classes, followed by an extensive discussion of the diverse roles of AKT and PI3K isoforms in immune cells. Based on this knowledge, it subsequently explains in more detail how specific isoforms are connected to immune-mediated diseases. The book concludes by highlighting the latest advances in the production of isoform-specific inhibitors and their use in various human diseases. This book is intended as a reference guide for students and researchers interested in the multifaceted aspects of PI3K biology.

Abstract

This volume examines all facets of the complex biology of Immunoglobulin E (IgE) antibodies, which play an essential role in the pathophysiology of allergic diseases and immunity to parasites. It highlights the unique mechanisms involved in the regulation of IgE production at both the molecular and cellular level. Furthermore, it discusses in detail novel findings on how the affinity, specificity and cross-reactivity of IgE can fine-tune mast cell responses to allergens. The book also explores the beneficial roles of IgE antibodies in immunity to helminthes and protection against tumors, and how the properties of IgE-mediated immunity are employed in the development of IgE therapeutic antibodies. All chapters were written by respected experts in their fields and will appeal to scientists and clinicians alike.

Abstract

En 2008, en France, 222 patients sont décédés faute d'avoir reçu un greffon à temps, alors que seulement 4 620 greffes avaient été réalisées pour 13 687 personnes en attente. La pénurie est particulièrement aiguë pour les malades qui ont besoin d'un rein : on compte en moyenne seulement 1 greffon disponible pour 3 malades. Cette situation est assez générale en Europe, mais moins grave dans certains pays qui ont su développer, de différentes manières, une plus grande mobilisation des deux sources de greffons : les donneurs décédés et les donneurs vivants. Le séminaire qui s'est tenu à Paris les 6 et 7 mai 2009 s'est proposé de contribuer à la réflexion des autorités en charge de la révision des lois de bioéthique ainsi que, plus généralement, des milieux médicaux et de l'opinion publique, en apportant un éclairage européen sur les solutions possibles au déficit constaté. Des personnalités faisant autorité - médecins et chirurgiens, mais aussi juristes, sociologues, philosophes et responsables administratifs venant d'Allemagne, d'Espagne, d'Italie, de Grande-Bretagne, de Norvège, des Pays-Bas et de Suède - ont été invitées à présenter leurs expériences et à débattre des aspects éthiques associés, en présence de leurs homologues français et de responsables politiques. Cet ouvrage transcrit les interventions et les débats, souvent vifs, qui les ont suivies. Penser la greffe aujourd'hui, c'est l'envisager à travers les enjeux de la société. Face aux certitudes médicales, chaque individu perçoit des incertitudes éthiques. Les défis de la science imposent la transparence, garantie d'une " nouvelle démocratie ". La greffe apparaît alors ambivalente, dans son fondement philosophique, juridique et social, comme dans sa pratique chirurgicale. Faut-il parler de don altruiste ou d'échange réciproque à propos des " éléments et produits du corps humain " ? Dans le cas d'un prélèvement sur une personne décédée, la mort devient-elle " utile " parce qu'utilisée ? S'agit-il de mutiler pour réparer, ou de reconstruire l'homme et de repousser ainsi les limites de la vie ? Sur le terrain, le nombre important des refus de prélèvements induit-il vraiment une " pénurie " d'organes ? Faut-il l'attribuer au manque d'information du public, à la méfiance à l'égard des médecins, à l'attachement à des valeurs personnelles, aux droits des familles, à l'incontournable présence de l'Etat ? Le législateur, depuis l'élaboration des lois de bioéthique jusqu'à leur application réglementaire encore inachevée, a tenté de réaliser un cadre protecteur pour la personne humaine. Y est-il parvenu ? Ces débats d'idées ainsi que les résultats inattendus de la première enquête nationale sur le don d'organes constituent le point le plus complet à ce jour sur le sujet du prélèvement et de la greffe. Ce livre est né de la volonté d'éclairer les citoyens et d'attirer l'attention des politiques sur ce constat : la greffe existe, elle se doit de rester humaine.
