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.

Toll-like receptors (TLRs) are pattern recognition receptors that allow innate immunity to protect our body against invading pathogens. They are alsoregulators of adaptive immunity. The human TLR was discovered quite recently, but its functional significance is known worldwide and today TLR agonists have been approved for use in humans. This book provides an overview of TLRs and their role in parasitic infections and neurodegenerative diseases. It is hoped that it will encourage readers to seek out the latest developments in TLRs.

Mammalian Toll-like receptors (TLRs) were first identified in 1997 based on their homology with Drosophila Toll, which mediates innate immunity in the fly. In recent years, the number of studies describing TLR expression and function in the nervous system has been increasing steadily and expanding beyond their traditional roles in infectious diseases to neurodegenerative disorders and injury. Interest in the field serves as the impetus for this volume in the Current Topics in Microbiology and Immunology series entitled "Toll-like receptors: Roles in Infection and Neuropathology". The first five chapters highlight more traditional roles for TLRs in infectious diseases of the CNS. The second half of the volume discusses recently emerging roles for TLRs in non-infectious neurodegenerative diseases and the challenges faced in these models with identifying endogenous ligands. Several conceptual theories are introduced in various chapters that deal with the dual nature of TLR engagement and whether these signals favor neuroprotective versus neurodegenerative outcomes. This volume should be informative for both experts as well as newcomers to the field of TLRs in the nervous system based on its coverage of basic TLR biology as well as specialization to discuss specific diseases of the nervous system where TLR function has been implicated. A must read for researchers interested in the dual role of these receptors in neuroinfection and neurodegeneration.

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".

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.

The innate immune system has evolved means to recognize and react suitably to foreign entities such as infectious agents. In many cases infectious microorganisms threaten the integrity and function of the target organs or tissues; therefore, consequent to their recognition the immune system becomes activated to ensure their elimination. Toll-like receptors (TLR) constitute a family of receptors specialized in the recognition of molecular patterns typically associated with infectious agents. Different TLRs exist, each selective for molecular entities and motifs belonging to a specific pathogen group. Consequently, it is thought that the molecular nature of invading microorganisms activates specific TLRs to drive adequate anti-infectious immunity. For instance, nucleic acid-specific, intracellular receptors (TLR3/7/8/9) are used to sense viruses and drive antiviral immunity, while other receptors (such as TLR2 and TLR4) recognize and promote immunity against bacteria, yeast, and fungi. Yet, it is becoming evident that activation of TLR pathways trigger mechanisms that not only stimulate but also regulate the immune system. For instance, TLR stimulation by viruses will drive antiviral interferon but also immunoregulatory cytokine production and regulatory T cell activation. Stimulation of TLRs by bacteria or using molecular agonists can also trigger both immune stimulatory and regulatory responses. TLR stimulation by infectious agents likely serves to activate but also control anti-infectious immunity, for instance prevent potential immunopathological tissue damage which can be caused by acute immune defense mechanisms. Previous work by us and others has shown that the immunoregulatory arm of TLR stimulation can additionally help control autoreactive processes in autoimmune disease. Hence, it is becoming established that gut commensals, which also play a crucial part in the control of autoimmune disease, establish immune regulatory mechanisms through activation of particular TLRs. In sum, it appears that TLRs are key immune players that not only stimulate but also regulate immune processes in health and disease. In this Research Topic, we wish to review the dual role of TLRs as activators and regulators of immune responses. We aim to motivate data-driven opinions as to the importance of context of TLR agonism for determining immune activation vs. regulation. The presentation of ongoing original works, as well as data and opinions around other innate immune receptors pertaining to this topic, are also encouraged.
