Cell adhesion is essential for the organization of multicellular organisms. Indeed, various types of cell adhesion receptors, including cadherins and integrins, are present in animals ranging from nematodes and insects to vertebrates. In this book, we focus on the integrin family, which is shared among all metazoans, but has expanded considerably with vertebrate evolution. Since the cloning of the first integrin subunit, some twenty years ago, integrin biology has been—and still is—a topic of intense study. Integrin-mediated adhesion is a regulated process that, in turn, regulates the organization of the actin cytoskeleton. Moreover, it has become clear from in vitro analyses that integrin-mediated adhesion can affect virtually all aspects of cellular behavior—including polarity, motility, proliferation, survival, and differentiation. This book aims to provide an extensive overview of the current knowledge about the regulation of developmental processes as well as the maintenance of proper tissue function, by integrin-mediated adhesion. In addition, key aspects of integrin cell biology are discussed. Chapter 1 of this book is meant as an introduction in integrin biology and is followed by a more in-depth discussion of the roles that integrins play in extracellular matrix assembly, in cell migration, and in the regulation of intracellular signaling cascades (Chapters 2-4). Subsequently, Chapters 5 and 6 discuss what has been learned about the role of integrins and associated proteins in animal development from genetic analysis of two invertebrates— the flatworm, C. elegans and the fruit fly, D. melanogaster. The relatively limited number of genes encoding adhesion-related proteins and the relative ease and speed with which genetic experiments can be performed in these animals, have allowed researchers to study the basic principles of integrin biology in vivo. Finally, Chapters 7-14 discuss how integrin-mediated adhesion regulates the development and functionality of the different mammalian organ systems, based to a large extent on (conditional) gene knockout studies in mice and on studies in human patients.
Chapters available from this book
Integrin Regulation of Mammary Gland Development
Matthew J. Naylor and Charles H. Streuli
The interaction between a cell and its microenvironment is critical in governing cellular function. Integrins, the major family of extracellular matrix receptors, link the matrix with the actin cytoskeleton and, together with providing a structural association between the inside and outside of the...
Integrins: An Overview of Structural and Functional Aspects
Erik H. J. Danen
Integrins are heterodimeric transmembrane receptors that mediate cell-adhesion.1 With their extracellular head region, most integrins bind extracellular matrix (ECM) glycoproteins such as laminins and collagens in basement membranes or connective tissue components like fibronectin. Others bind cou...
The Role of Integrins in Cell Migration
Bernhard Wehrle-Haller
Migration and Motility are essential components of the behavioral repertoire of a cell. During embryogenesis cells move in sheets or loosely attached populations to create complex tissues. In the adult, cell motility is crucial to maintain immunity, or repair damaged tissues. Uncontrolled cell adhes...
Integrins in Urogenital Development
Jordan A. Kreidberg
The urogenital system is a complex system composed of multiple organs, most notably the kidneys and gonads, as well as many other glandular components and connective tissues. This review will concentrate on the roles of integrins in the developing kidney, as integrins have been less well studied in ...
Cell Adhesion in Nervous System Development:
Claudia S. Barros and Ulrich Müller
Integrins are a family of cell surface receptors that are expressed in many if not all tissues. Integrins mediate interactions with different ligands including extracellular matrix glyco- proteins, cell surface counter-receptors, proteases and pathogens. The study of integrins has provided compel...
Insights into Integrin Function in Skeletal Muscle
Lisa K. Rogers and Ulrike Mayer
Skeletal muscle accounts for 40% of the human body and is the major consumer of body fuels. Contraction within muscle fibers by ATP consumption generates the force required for our body movement, but the coordinated transmission of this force through the muscle cell membrane to the surrounding ba...
The Role of Integrins in Vasculogenesis and Angiogenesis
Andrew R. Reynolds, Kate A. Scott and Kairbaan M. Hodivala-Dilke*
This chapter aims to summarise the current literature regarding the role of integrins in blood vessel growth. Blood vessels arise via vasculogenesis and angiogenesis and we begin by giving a brief introduction to these processes. We then introduce the methods most commonly used for studying the f...
Integrins in the Skin
Cord Brakebusch
The skin protects the body of mammalians from mechanical and chemical damage, is a barrier against infections and prevents dehydration. It can be divided into an upper layer, called epidermis, and a lower layer, called dermis (Fig. 1). The epidermis consists mainly of keratinocytes, while the der...
Roles for Integrins and Associated Proteins in the Haematopoietic System
Alessandra Cambi, Suzanne F.G. van Helden and Carl G. Figdor
The haematopoietic system is a highly dynamic system where cell adhesion and cell migration are tightly controlled. During both embryonic and adult haematopoiesis, the finely orchestrated action of several integrins contributes to the generation of all different mature blood cells. Within the imm...
Integrins and Associated Proteins in Drosophila Development
Maithreyi Narasimha and Nicholas H. Brown
We discuss insights into integrin function obtained through phenotypic and structure function analysis of integrins and associated proteins in the fruitfly, Drosophila melanogaster. Integrins contribute to fly development by mediating both dynamic and stable adhesive interactions. The minimal red...
Integrins in Skeletal Cell Function and Development
Michael A. Horton and Miep H. Helfrich
Genes for 18 ? and 8 ? integrin subunits have been identified in vertebrates, their protein products associating into 24 different heterodimeric membrane receptors. Skeletal cells – osteoclasts, osteoblasts and chondrocytes – exhibit characteristic integrin profiles and for some there is good evi...
The Essence of Integrin Signal Transduction:Assembly of Dynamic Scaffolds and Cross-Talk with Other Receptors
Sara Cabodi and Paola Defilippi
Integrin signalling has a critical function in organizing cells in tissues during both embryonic development and tissue repair. Following their binding to the extracellular ligands, the intracellular signalling pathways triggered by integrins are directed to two major functions: organisation of t...
Integrins in Extracellular Matrix Assembly
Roumen Pankov and Katherine Clark
Integrin receptors are used by cells not only to bind, but also to actively organize extracellular matrices. They contribute in the in vivo polymerization of the major matrix constituents – fibronectin, laminin and collagen. Integrin participation in this process varies from indispensable, active...
C. elegans Integrins
Michel Labouesse and Elisabeth Georges-Labouesse
C. elegans has only one beta integrin chain, called PAT-3, and two alpha integrin chains, called PAT-2 and INA-1. C. elegans integrins are essential for muscle anchoring to the epidermis, cell migration, axon outgrowth and fasciculation, and epithelial morphogenesis. Genetic analysis of this simp...
