Toll Like Receptors In Health And Disease

The current book is focussed on the Toll-like receptors (TLRs), which are the first pattern recognition receptors (PRRs) discovered in humans. For example, TLR4 was first recognized in humans in 1997 as a PRR recognizing the Gram-negative bacterial lipopolysaccharide (LPS). This discovery revolutionized the field of innate immunity and filled the long-standing gap in the pathogen recognition by the immune system. Now, it is well established that humans have 10 (TLR1-TLR10) and mice have 12 (TLR1-TLR13) functional TLRs, excluding TLR10 that is present as a defective pseudogene. TLRs are present as both membrane-bound extracellular (TLR1, TLR2, TLR4, TLR5, TLR6, and TLR10) and intracellular (TLR3, TLR7, TLR8, and TLR9) PRRs in humans, which identify different pathogen or microbe-associated molecular patterns (PAMPs or MAMPs) and death or damage-associated molecular patterns (DAMPs) released by the host cells. A lot of development in the TLR biology has occurred in last 24 years since there first discovery in humans. The book is intended to describe their role in the host defence, human reproduction, non-infectious sterile inflammatory conditions, including brain immunity and cerebrovascular diseases, signaling mechanisms, adaptive immunity, and their targeting for drug development.

Overall recent research on TLRs has led to tremendous increase in our understanding of early steps in pathogen recognition and will presumably lead to potent TLR targeting therapeutics in the future. This book reviews and highlights our recent understanding on the function and ligands of TLRs as well as their role in autoimmunity, dendritic cell activation and target structures for therapeutic intervention.

The book focuses on various aspects and properties of innate immunity, whose deep understanding is integral for safeguarding the human race from further loss of resources and economies due to innate immune response-mediated diseases. Throughout this book, we examine the individual mechanisms by which the innate immune response acts to protect the host from pathogenic infectious agents and other non-communicable diseases. Written by experts in the field, the volume discusses the significance of macrophages in infectious disease, tumor metabolism, and muscular disorders. Chapters cover such topics as the fate of differentiated macrophages and the molecular pathways that are important for the pathologic role of macrophages.

Advances in itch research have elucidated differences between itch and pain but have also blurred the distinction between them. There is a long debate about how somatic sensations including touch, pain, itch, and temperature sensitivity are encoded by the nervous system. Research suggests that each sensory modality is processed along a fixed, direct-line communication system from the skin to the brain. Itch: Mechanisms and Treatment presents a timely update on all aspects of itch research and the clinical treatment of itch that accompanies many dermatological conditions including psoriasis, neuropathic itch, cutaneous t-cells lymphomas, and systemic diseases such as kidney and liver disease and cancer. Composed of contributions from distinguished researchers around the world, the book explores topics such as: Neuropathic itch Peripheral neuronal mechanism of itch The role of PAR-2 in neuroimmune communication and itch Mrgprs as itch receptors The role of interleukin-31 and oncostatin M in itch and neuroimmune communication Spinal coding of itch and pain Spinal microcircuits and the regulation of itch Examining new findings on cellular and molecular mechanisms, the book is a compendium of the most current research on itch, its prevalence in society, and the problems associated with treatment.

This e-book is a review on current understanding of the role of toll-like receptors (TLRs) in the lung in health and disease. Topics covered include 1) the expression, function and activation of TLRs during bacterial, viral and fungal infection of the airways, 2) the role of TLRs in the pathogenesis of genetic and environmental pulmonary disorders, and 3) TLR biology in lung transplantation. Each chapter highlights recent advances in a selected domain in lung disease research. This e-book serves as a comprehensive resource for both scientists and clinicians studying innate immune mechanisms in the lung and provides a single reference comprising both basic and specialized information.

In addition to their invaluable role in the fight against infection, Toll-Like Receptors (TLRs) in an under- or over-active state can lead to the pathogenesis of disease, making these receptors a key focal point for many research laboratories. In Toll-Like Receptors: Methods and Protocols, experts in the field contribute techniques currently used to study TLRs, their downstream signalling pathways, and their role in the pathogenesis of disease, with sections examining TLR expression and the application of genetic techniques and microarray analysis to TLR research. Written in the highly successful Methods in Molecular BiologyTM series format, chapters include brief introductions to the topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and Notes sections highlighting tips on troubleshooting and avoiding known pitfalls. Versatile and cutting-edge, Toll-Like Receptors: Methods and Protocols provides an ideal manual for a wide range of biologists and medical researchers studying these vital components of the immune system.

The Janeway's Immunobiology CD-ROM, Immunobiology Interactive, is included with each book, and can be purchased separately. It contains animations and videos with voiceover narration, as well as the figures from the text for presentation purposes.

Toll Receptors and the Renaissance of Innate Immunity Elizabeth H. Bassett and Tina Rich Overview n the last few pages of Immunology: The Science of Self-Nonself Discrimination Jan Klein ponders on what he would study if he were to start over in the lab. ^ Dismissing the I antibody, MHC, the T-cell and parasitology, he considers instead the phylogeny of immune reactions, particularly in ancient phyla. As for a favored cell he chooses the macrophage. Describ ing it as a ^^MddchenfUr alles," (all purpose kitchen maid) Klein believed that this immunocyte still had secrets to reveal. Toll-Like Receptor (TLR) biology would prove to be one of these secrets. Analyses of the evolution of these receptors (Tolls and TLRs) have also helped us to rethink immune system phylogeny. In the first part of this chapter the history of the discovery of Toll and TLR biology is described. The evolution of the TLR genes and theories of immune function are covered in later sections. The remainder of this book presents work from nine groups active in the field. In the first chapter, "The Function of Toll-Like Receptors", Zlatko Dembic sets the stage by introducing us to many of the components of the immune system and their relationships vis a vis Toll receptors. Zlatko finishes his chapter with a discussion about current immune system models and contributes his own 'integrity model'. Work from the laboratory of Nicholas Gay follows this in "Structures and Motifs Involved in Toll Signaling".

The Innate Immune Response to Non-infectious Stressors: Human and Animal Models highlights fundamental mechanisms of stress response and important findings on how the immune system is affected, and in turn affects such a response. In addition, this book covers the crucial link between stress response and energy metabolism, prompts a re-appraisal of some crucial issues, and helps to define research priorities in this fascinating, somehow elusive field of investigation. Provides insights into the fundamental homeostatic processes vis-à-vis stressors to help in investigation Illustrates the depicted tenets and how to offset them against established models of response to physical and psychotic stressors in both animals and humans Covers the crucial issue of the immune response to endocrine disruptors Includes immunological parameters as reporter system of environmental adaptation Provides many illustrative examples to foster reader understanding
