Fungal infections represent nowadays a significant burden on the healthcare system of most of the countries, and are among the infections with the highest mortality rates. This has fostered the study of the interaction of these organisms with the human host. The outer most layer of a fungal cell is the cell wall, and together with the secreted components into the extracellular compartment, are the first lines of contact with the host cells. This interaction is critical for tissue adhesion, colonization and damage. In addition, these fungal extracellular components will define the outcome of the interaction with the host immune cells, leading either to the establishment of a protective antifungal immune response or to an immune-evasive mechanism by the fungal cell. On the other hand, our immune system has effectively evolved to deal with fungal pathogens, developing strategies for cell eradication, burden control, or antigen presentation from the innate branch to the adaptive immune response. Here, we provide a series of comprehensive review papers dealing with both aspect of the interaction fungus-immune cells: the role of virulence factors and cell wall components during such interaction, and the recent advances in the study of cellular receptors in the establishment of a protective anti-fungal immune response.

This book discusses typical skin diseases from an immunological point of view, introducing the latest immunological techniques and practices. It begins with a brief overview of the human immune system, including the basic concepts and principles as well as the general symbols used in immunology. Part Two describes the human skin as an integral part of the immune system, explaining the immunological roles of major cellular and molecular composites in the skin. Part Three illustrates typical skin diseases that have immunological involvement (immunodermatological conditions). It describes 40 skin diseases, focusing on immunological causes, pathogenesis, pattern of reaction and treatment choices and responses. The final part discusses advanced immunodiagnostics and immunotherapy in dermatology, providing detailed descriptions of immune techniques for the diagnosis of skin diseases, their principles and background, indications, requirements for sampling, test protocols, interpretation of results and trouble shooting. This work offers insights into both the systemic immune system and the skin immune system, and integrates the information into discussions of clinical diseases, relevant immune techniques and immunological drugs. Presenting the latest advances in clinical immunology, it is an invaluable resource for dermatologists, residents and graduate students in dermatology.

Fungi are found in virtually every environment, and comprise a significant portion of the normal microflora of healthy individuals. Some species of fungi are aeroallergen sources capable of inducing sensitization and causing exacerbation of asthma and respiratory allergy. Others are transmissible between hosts and may cause no symptoms in healthy individuals. However, immune suppressed individuals may develop invasive disease marked by tissue invasion with a potential for widespread dissemination. Existing therapies for patients consist of antifungal drugs, yet these require prolonged administration with the possibility of adverse side effects, and may be rendered ineffective by the emergence of antifungal-resistant strains. It is therefore of interest to increase our understanding of host-pathogen interactions in order to facilitate the development of new therapies for individuals suffering from fungal infection and disease. These early interactions are shaped by an array of constituent and secreted factors that stimulate or inhibit host immune responses toward protective or detrimental immunity. Likewise, an array of preformed factors and tissue-resident cells provide early protection from fungal infection and provide extracellular signals that result in localized recruitment of inflammatory cells and determine the character of subsequent adaptive antifungal immunity. This Research Topic explores the host and fungal pathways that program innate and adaptive immunity and the immune cells, molecules, and regulatory pathways that comprise protective or detrimental responses to fungal exposure or infection. Over 200 authors contributed reviews, opinions, or original research focusing on antifungal immunity in humans and in experimental models. We believe that the results of these efforts provide a benchmark for further advances and improved antifungal therapies.

This treatise is focused on early aspects of fungal pathogenesis in plant and animal hosts. Our aim in choosing the topics and contributors was to demonstrate common approaches to studies of fungal-plant and fungal-animal interactions, particularly at the biochemical and molecular Ievels. For example, the initial events of adh«sion of fungal spores to the exposed surface tissues of the host are essential for subsequent invasion of the plant or animal and establishment of pathogenesis. A point of consensus among investigators who have directed their attention to such events in plants, insects, and vertebrates isthat spore adhesion to the host cuticle or epithelium is more than a simple binding event. lt is a complex and potentially pivotal process in fungal-plant interactions which "may involve the secretion of ftuids that prepare the infection court for the development of morphological stages of the germling" and subsequent invasion of the host (Nicholson and Epstein, Chapter 1). The attachment of the fungal propagule to the arthropod cuticle is also "mediated by the chemical components present on the outer layer of the spore wall and the epicuticle . . . . Initial attachment may be reinforced further by either the active secretion of adhesive materials or the modification of spore wall materiallocated at the [fungal spore arthropod] cuticle interface (Boucias and Pendland, Chapter 5).
