Peptidergic G Protein-coupled Receptors


Book Description

Peptides are a rapidly growing class of mediators whose activity regulates homeostasis as well as pathological processes. Most of the peptide-activated receptors belong to the superfamily of 7 transmembrane domain receptors coupled to G proteins. Peptides of different sizes (from a few to more than 100 aminoacids) activate peptidergic receptors by interacting at specific sites, that often differ from those where antagonists bind. Other receptors are activated by proteases that, by cleaving the receptor extracellular region, unmask a tethered ligand. G protein-coupled receptors for chemokines represent the way of entry of the HIV virus in target cells. The great impact of non peptide agonist/antagonists in current and future medicine reflects these large variety of functions and modes of activation of peptidergic G protein-coupled receptors.







Immunopharmacology of Epithelial Barriers


Book Description

The realisation that epithelial tissues are not simply passive barriers to the adsorption of materials into internal environments has brought about an enormous growth of investigation of mucosal functions and their active and passive protective roles. Epithelia are highly organized but complex structures, subserving numerous functions, including immunological defence. The use of pharmacological tools in these systems is increasing, which is improving our understanding of epithelial immunobiology. This volume adopts a step-by-step approach, whereby each chapter builds upon the previous one, progressively adding important foundation information, culminating in a series of chapters concerning particular epithelia, including respiratory, gastrointestinal, renal and ocular. The result is a comprehensive but integrated treatise of epithelial function and its immunopharmacology, which aims to serve as an appropriate starting point at which the clinical pulmonologist and the research scientist can obtain an appreciation of some aspects of epithelial immunopharmacology as they are currently understood.







Allergy and the Nervous System


Book Description

In recent decades, it has become increasingly clear that the immune and nervous systems communicate with each other in a bidirectional way. The role of chronic stress in allergic disease and inflammation has been confirmed and raises the important question of how psychosocial factors influence the outcome of allergic conditions. This book explains the roles of the autonomic, peripheral and central nervous systems in allergy and asthma. With contributions from leading authorities - both clinicians and basic researchers - it covers a wide range of topics from psychology over epigenetics to brain imaging. The 15 invited reviews discuss topics such as the role of stress in allergy and asthma, the concept of programming in utero and in childhood and adulthood, the significance of neurotrophins, and the involvement of the nervous system in the lung in asthma and lung inflammation. The interactions between mast cells and the nervous system are examined as well as the role of the gut microbiome in regulating the hypothalamic-pituitary-adrenal axis and the stress response. Further chapters are devoted to neural and behavioral changes associated with food allergy, the role of the neuroendocrine system in the skin, and the way in which itch is processed by the brain. Unique in its field, this valuable volume is recommended reading not only for allergologists, psychologists specializing in allergy and somatic manifestations, respirologists and asthma researchers, but for anyone interested in psychoneuroimmunology.

Immunopharmacology of Respiratory System


Book Description

Immunopharmacology represents the boundary between the immune system and chemical mediators of the inflammatory and neuroendocrine responses. The subject as applied to the respiratory system embraces most of the common non-malignant lung diseases of which asthma and allied disorders are the most prevalent. An understanding of the underlying mechanisms of the disorders provides rationale for prevention and drug treatment as well as creating opportunities for novel drug development. Immunopharmacology of Respiratory System embraces all of these principles and should enable the reader to become rapidly updated in an area of medical importance. - Focuses on aspects of disease pathogenesis that are common to a variety of lung disorders - Includes coverage of the mechanisms of asthma - origin, progression, and novel therapeutic interventions - This volume is another in the "Systems" section of the Handbook of Immunopharmacology
