The Fungal Cell Wall

This book illustrates, that the fungal cell wall is critical for the biology and ecology of all fungi and especially for human fungal pathogens. Readers will learn, that the composition of the fungal cell wall is a unique structure, which cannot be found in the human host. Consequently, the chapters outline, how the immune systems of both animals and humans have evolved to recognize conserved and unique elements of the fungal cell wall. As an application example, the authors also show, that the three-dimensional structures of the cell wall are excellent targets for the development of antifungal agents and chemotherapeutic strategies. With the combination of biological findings and medical outlooks, this volume is a fascinating read for scientists, clinicians and biomedical students.

Fungal Cell Wall: Structure, Synthesis, and Assembly, Second Edition is a compendium of information on the chemical structure, synthesis, and organization of the cell wall of fungi. Reviewing the past 20 years of research in the field, it discusses experimental evidence that demonstrates the role of the cell wall in the growth, development, morphog

The fungal cell wall is a shield that protects the cells against changes in the extracellular environment, and from the high internal pressure generated during cell growth. These protective attributes are associated with cell wall robustness and strength, but at the same time the wall has to be plastic and dynamic to allow cell growth and communication with the external environment. The main components of the cell wall are sugars, proteins and lipids. Sugars are the most abundant components of the wall, and are mostly present as polysaccharides of glucose (alpha- and beta-glucans), N-acetylglucosamine (chitin), and glucosamine (chitosan). Most of the cell wall proteins are glycoproteins modified by a glycolipid and/or oligosaccharides covalently attached to asparagine (N-linked glycosylation) or serine/threonine residues (O-linked glycosylation). These wall proteins play important roles in cell wall integrity and structure, sensing changes in the extracellular environment, and some of them have adhesive properties and hydrolytic activities.

This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area!

The first book of its kind to focus on the diagnosis, prevention, and treatment of patients with fungal infections, this definitive reference returns in a completely revised, full-color new edition. It presents specific recommendations for understanding, controlling, and preventing fungal infections based upon underlying principles of epidemiology and infection control policy, pathogenesis, immunology, histopathology, and laboratory diagnosis and antifungal therapy. More than 560 photographs, illustrations, and tables depict conditions as they appear in real life and equip you to identify clinical manifestations with accuracy. Expanded therapy content helps you implement the most appropriate treatment quickly, and a bonus CD-ROM-featuring all of the images from the text-enables you to enhance your electronic presentations. Includes specific recommendations for diagnosing, preventing, and treating fungal infections in various patient populations based upon underlying principles of epidemiology and infection control policy, pathogenesis, immunology, histopathology, and laboratory diagnosis and antifungal therapy. Covers etiologic agents of disease, fungal infections in special hosts such as pediatric patients and patients with cancer and HIV, infections of specific organ systems, and more, to make you aware of the special considerations involved in certain cases. Features clinically useful and reader-friendly practical tools-including algorithms, slides, graphs, pictorials, photographs, and radiographs-that better illustrate and communicate essential points, promote efficient use in a variety of clinical and academic settings, and facilitate slide making for lectures and presentations. Offers a CD-ROM containing all of the book's images for use in your electronic presentations. Offers more clinically relevant images-more than 300 in full color for the first time-to facilitate diagnosis. Features expanded therapy-related content, including up-to-date treatment strategies and drug selection and dosing guidelines. Includes several new sections in the chapter on fungal infections in cancer patients that reflect the formidable clinical challenges these infections continue to present. Presents the work of additional international contributors who have defined many of the key issues in the field, providing more of a global perspective on the best diagnostic and management approaches. Uses a new, full-color design to enhance readability and ease of access to information.

Despite the many advances made during the last decade in various aspects of fungal biochemistry, there have been very few volumes devoted to the sub ject in recent years. This lack is all the more surprising in view of the increas ing use of fungi in gene manipulation studies and in biotechnological ap plications, and of the current interest in the biorational discovery of novel agents for the control of fungal pathogens of plants and humans. We hope that this book goes some way to rectifying this situation by providing an up to-date account of selected developments in two important areas, namely cell walls and membranes. Topics included in the book concern both yeasts and filamentous fungi. Although the main emphasis is on biogenesis, functional aspects are also discussed, e.g. the role of glycoproteins in recognition of sterols in mem branes and of calcium in regulation. Several contributions describe in terference with the 'normal' biochemistry of cell walls and membranes with a view to increasing fundamental knowledge, but also highly relevant to the design of new fungicides and antimycotics. The steadily increasing impact of molecular biology on the study of fungal biochemistry is highlighted throughout.

In 1968 when Cell Walls and Membranes was published it was still reasonable to attempt to write a book covering the whole subject. Accordingly this edition of the book had something to say about walls from micro-organisms and plants as well as about membranes from bacteria and animal cells. A decade later this is manifestly impossible. Knowledge about almost all the subjects has grown explosively, par ticularly about membranes and the biosynthesis of macromolecules. Moreover aspects of the subject that were still in a relatively primitive state ten years ago have grown into highly sophisticated subjects worthy of extended treatment. The result is that the present book has had to be confined to structures and functions relating to only one division of the biological kingdom, namely micro-organisms. Even then severe limitations have had to be made to keep the task within the time available to the authors and their expertise. A few of the titles of chapters such as those on the isolation of walls and membranes, the structure of the components of bacterial and micro-fungal walls and their biosynthesis remain from the earlier book. These chapters have been almost completely rewritten and a number of quite new chapters added on topics such as the action of the antibiotics that inhibit bacterial wall syn thesis, on the function of bacterial membranes, and the bacterial autolysins.
