The vertebrate immune system is distinctive among defense systems of multicellular organisms. In addition to nonspecific immunity, it generates a randomized array of millions of antigen receptors (immunoglobulins and T-cell receptors). A subset of these receptors are critical for binding to invading microbes or biochemicals from them to tag the microbes for elimination. Three site-directed DNA modification processes are critical to this process in vertebrates. V(D)J recombination generates the array of exons that encode the antigen binding pockets. Recent work summarized in this volume...

This volume of Current Topics in Microbiology and Immunology is concerned with a class of molecules that are the most potent polyclonal stimulators of T lymphocytes of several species. These molecules have been named "superantigens" because they use a mechanism of T cell stimulation closely mimicking MHC-restricted recognition of specific antigen: they act on variable parts of T cell antigen receptors and are presented by MHC class II molecules. Prototypes of these molecules are the pyrogenic exotoxins produced by S. aureus and S. pyogenes, of which the staphylococcal enterotoxins and the...

The genome of retroviruses contains three major coding regions for virion proteins, gag, pol and env. Gag encompasses information for nonglycosylated viral proteins that form the matrix, the capsid and the nucleoprotein structures. From pol derive reverse transcriptase and integrase, and env codes for the surface glycoproteins of the virion which consist of a transmembrane and a surface domain, linked by disulfide bonds. A viral protease is derived eitherfrom the gagorfrom the pol coding region, depending on the virus. Simple retroviruses contain only this elementary gag, pol, and env coding...

Scientists often look askance at their colleagues whose research appears too strongly focused on a single gene or gene product. We are supposed to be interested in the "big picture" and excessive zeal in pursuit of a single pixel might seem to border on an obsession that is likely to yield only details. However as this volume of Current Topics in Microbiology and Immunology demonstrates, this is certainly not the case for myc. Intense study of this en- matic proto-oncogene over the last twenty years has only broadened our view of its functions and led to insights into mechanisms relating to...

Rhabdoviruses have a very wide host range and have been isolated from plants, insects, and almost from all vertebrates including fish and primates. The Rhabdoviridae family consists of six genera which have all been associated with diseases. While rhabdoviruses that are etiological agents of human diseases can cause serious public health problems, other members of this family that infect domestic livestock and agricultural plants can also cause enormous economic loss.

The term humanized mouse in this text refers to a mouse in which human tissues and cells have been transplanted and show the same biological function as they do in the human body. That is, the physiological properties and functions of tra- planted human tissues and cells can be analyzed in the mouse instead of using a living human body. It should therefore be possible to study the pathophysiology and treatment of human diseases in mice with good reproducibility. Thus, the hum- ized mouse can be used as a potent tool in both basic and clinical research in the future. The development of...

Phosphoinositides (PIs) are minor components of cellular membranes that play critical regulatory roles in several intracellular functions. This book describes the main enzymes regulating the turnover of each of the seven PIs in mammalian cells, some of their intracellular functions and some evidence of their involvement in human diseases. Due to the complex inter-relation between the distinct PIs and the plethora of functions that they can regulate inside a cell, this book is not meant to be a comprehensive coverage of all aspects of PIs signalling but rather an overview on the current state...

This volume offers an overview of the various aspects involved in the ability of fungi to damage host cells, and discusses cutting-edge approaches to the study of fungal pathogenesis. The first chapter illustrate the key roles of glycans and pigments, the most abundant surface components in fungal cells, in their interactions with host cells. The connections between cellular physiology and fungal pathogenesis are then discussed in the following chapters. Physiology-related processes affecting pathogenesis include fungal secretion, morphological transitions, and response to light.

This volume explores several aspects of how antibodies mediate their activity in vivo, ranging from cancer immunotherapy to autoimmunity, infection, and vaccination. Divided into seven chapters, it provides in-depth insights into how antibodies and especially the antibody fragment crystallizable (Fc) domain modulate immune responses and antibody activity. The book begins by discussing evolutionary aspects of how the family of Fc receptors that are the key molecules for antibody activity evolved. In turn, it addresses the molecular and cellular pathways underlying IgG activity in cancer...
