Available in PDF, EPUB and Kindle. Book excerpt: There has been a steady and continued research effort directed to understanding both the function and the role of mast cells and basophils ever since these cells were first described at the end of the nineteenth century. One of the most significant advances has perhaps been the appreciation of the fact that mast cells do not represent a single homogenous population of cells: they display heterogeneity at the morphological, biochemical and functional levels. The one characteristic that unites all types of mast cells and basophils appears to be the possession of the high affinity membrane receptor for immunoglobulin E, through which the cells may be stimulated. This volume begins with a review of the origin and development of mast cells and basophils. It continues by reviewing our knowledge of the stimuli to mast cells and basophils and the biochemical mechanisms which link the signal generated by stimulus to the response machinery of the cell. Further chapters deal with the drug control of mast cell and basophil responses, the heterogeneity of the cells' functions and the mediators' release by the cells, along with the morphological aspects of the cells' function. This book is completed by a selection of examples which examine the role of the mast cells or basophils in lung, skin and gastrointestinal tract. However, the role of the mast cell with regard to normal physiology, remains an open question. This book aims to provide an up-to-date account of mast cell and basophil biology, together with an insight into the functional relevance of these cells in some tissue types.

Available in PDF, EPUB and Kindle. Book excerpt: In 1879 Paul Ehrlich first described the mast cell as a tissue fixed cell contain ing many granules which, when stained with basic dyes, such as toluidine blue, changed the colour spectrum of the dye in a process called meta chromasia. Since this early description, pathologists, physicians and pharmacologists have been fascinated by this cell on account of its central involvement in human allergic diseases. Approximately four decades after Ehrlich's first description of the mast cell, Prausnitz and Kiistner reported their pioneer experiment, demonstrating that the immediate skin wheal response to allergen could be passively transferred with serum. They named the antigen-specific serum factor reagin. A further four and one half decades had to pass before the connection between the mast cell and reagin could be made with the identification of reagin as an immunoglobulin E by Johansson and Ishizaka and its unique property to bind with high affinity to specific receptors on mast cells and basophils. Meanwhile in the 1920s Coca published a series of papers in which he described the clinical features of acute allergic responses and first used the term atopy. This, together with the fundamental pharmacological studies of Sir Henry Dale in identifying histamine as one mediator of the acute ana phylactic reaction, provided the second approach which eventually linked the mast cell to allergic tissue reactions. Indeed, it was Best, working in Dale's group who first showed that histamine was a chemical stored in mast cells.

This book was released on 2014-03-20 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mast cells are tissue-localized cells that play an important role in immunity and inflammation. Following an offensive event they act as cellular sensors that via the activation of cell surface receptors launch a cellular response culminating in the release of a whole set of inflammatory mediators and products. This response is initially destined to restore tissue homeostasis, but in case of chronic injury or deregulation also promotes pathology. To further understand the action of mast cells in their environmental context it is necessary to decipher the molecular mechanisms of their activation as well as the ensuing cellular responses. This will allow identification of new strategies to promote their beneficial actions or, at the contrary, to interfere with their pathological consequences. While in the past many studies have focused on responses engaged by high affinity IgE receptor because of its implication in the allergic response, it has become clear that mast cells can be activated by multiple types of receptors initiating an intense molecular crosstalk between receptors and signaling pathways that can either synergize, antagonize and in some cases produce new types of responses. Mast cells can indeed react with an astounding diverse array of cellular responses that sometimes are engaged selectively. This Research Topic will focus on selected articles that shed some new light on the molecular mechanisms of mast cell activation, the possible crosstalk between signaling pathways and the ensuing cellular responses that allow mast cells to act as cellular sensors in tissues.

This book was released on 2016 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fc[epsilon]RI is a multi-subunit receptor found on the surface of mast cells and basophils and binds immunoglobulin E (IgE) with high affinity. Stimulation of this receptor, typically via antigen-mediated crosslinking of IgE, can lead to release of histamine and other mediators that are involved in the allergic immune response. Thus, understanding the workings of Fc[epsilon]RI-mediated signaling brings us closer to understanding one of the most widespread health conditions in the developed world. Fc[epsilon]RI-mediated signaling processes are inherently complex, involving highly interconnected systems in which quantitative factors can play a decisive role. Such systems can be difficult to decipher using intuition alone, but computational models can extend our reasoning abilities and enable us to develop nontrivial hypotheses that generate experimentally testable predictions. To develop a systems-level understanding of how combinations of non-covalent interactions and post-translational modifications are regulated to impact cellular decisionmaking, we developed a computational interaction library. The library consists of executable rules for protein-protein and protein-lipid interactions. The library is visualized to facilitate understanding of network circuitry and identification of network motifs. Using this library, we investigated branching pathways from the adaptor protein Lat, which influence production of the phospholipid phosphatidylinositol (3,4,5)trisphosphate (PIP3) at the plasma membrane and the soluble second messenger inositol trisphosphate (IP3). We found that inclusion of a positive feedback loop gives rise to a bistable switch, which may ensure robust responses to stimulation above a threshold level. Such robustness has been observed experimentally for some readouts. We also developed a model that proposes an explanation for experimentally observed oscillations in Ca2+ concentration, which is an important outcome of Fc[epsilon]RI stimulation. To investigate Fc[epsilon]RI signaling from another angle, we modeled interactions between the receptor and a structurally defined ligand for IgE. We parameterized the model for consistency with kinetic fluorescence data as well as super-resolution imaging measurements of antigen-induced receptor aggregation. To facilitate this study, we developed a specialized tool for fitting biochemical models to experimental data. Finally, we examined how patterns of exposure to stimulatory and non-stimulatory ligands affect mast cells' secretory responses. Through iterative modeling and experimental tests, we learned that a tug-of-war between positive signals from the tyrosine kinase Syk and negative signals from the lipid phosphatase Ship-1 govern the magnitude of responses, with the adaptor protein Shc1 influencing how the balance of positive and negative signals changes with time.

Available in PDF, EPUB and Kindle. Book excerpt: IgE antibodies interact with the high affinity IgE Fc receptor (Fc [epsilon] RI) expressed on mast cells and basophils, and the low affinity IgE Fc receptor (CD23) on B cells. These interactions are directly involved in triggering the allergen-specific activation of inflammatory responses. The IgE-Fc region, comprising the C-terminal domains of the IgE heavy chain, binds Fc [epsilon] RI and the crystal structures of the human IgE-Fc alone and IgE-Fc complexes exhibited IgE-Fc conformational flexibility. In addition, the crystal structure of IgE-Fc bound to CD23 indicated a preference of CD23 for a closed conformation of the IgE-Fc incompatible with Fc [epsilon] RI binding. These observations suggested the importance of IgE conformational dynamics for its receptor binding mechanism and the potential to identify non-classical or allosteric inhibitors for IgE-receptor interactions. To investigate IgE dynamics and its role in receptor binding and inhibition, I have employed 5 experimental approaches: 1) IgE-Fc mutants trapped by an engineered disulfide bond, blocking Fc [epsilon] RI but not IgE inhibitor binding, 2) a fluorescence assay for IgE-Fc:Fc [epsilon] RI binding and inhibition that can distinguish IgE-inhibitors based on their proximity to the Fc [epsilon] RI binding site, 3) the determination of the E2_79 crystal structure showing that the IgE inhibitor E2_79 binds IgE-Fc outside the Fc [epsilon] RI-binding site and acts through a facilitated dissociation mechanism to block receptor binding, 4) the development of a TR-FRET assay suitable for high-throughput screening for small molecule inhibitors of IgE-receptor binding, and 5) a single-molecule FRET approach to characterize the conformational states of the IgE-Fc3-4 and observe changes upon Fc [epsilon] RI, CD23, and E2_79. These experiments revealed different conformational requirements for IgE binding, identified a disruptive inhibitor that actively dissociates preformed receptor complexes, and provided direct observation of receptor binding-induced IgE-Fc conformational changes. This work provides a new perspective on the role of IgE dynamics in receptor binding and inhibition, and makes possible the development of new disruptive inhibitors for IgE-receptor binding acting through non-classical or allosteric mechanisms.

This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The high affinity immunoglobulin E (IgE ) receptor (Fc[epsilon]RI) is a member of a family of related antigen receptors with conserved structure and similar roles in initiating intracellular signaling in response to an outside stimulus. In mammalian cells, Fc[epsilon]RI is found primarily on the surface of mast cells and basophils. Activation of this receptor by multivalent antigen triggers a series of intracellular signaling events that ultimately lead to the secretion of preformed mediators, such as histamine and serotonin, which are responsible for allergic reactions. Our recent efforts in the study of immunoreceptor signaling have focused on the participation of the plasma membrane and the actin cytoskeleton. However, tools for investigating biomolecular dynamics and interactions that occur within close proximity to the plasma membrane of living cells are somewhat limited. Micro-fabricated surfaces have been used for applications in cell and tissue engineering, although their full potential has not been explored, particularly in the area of molecular cell biology. We have recently developed a polymer lift-off method for localizing the initial stimulus to micron size patches of antigens such that assembly of signaling components could be visualized with selective fluorescent labeling and confocal microscopy. Employing these technologies we have investigated fundamental mechanisms in immune cell signaling, specifically IgE receptor (Fc[epsilon]RI) signaling involved in allergic responses on mast cells. In past years, our group has observed spatially and temporally resolved responses, including receptor phosphorylation, selective accumulation of Lyn kinase and other membrane components. In this work, I have applied these tools to investigate functional and structural implications of the actin cytoskeleton regulation of Fc[epsilon]RI signaling and the cytoskeletal dependence of activated receptor internalization. I have shown that particular actin binding proteins, paxillin, talin and vinculin co-redistribute at the patterned antigen and clustered receptors in a similar time course as polymerized actin. These proteins have been extensively characterized in the context of integrin signaling and focal adhesion assembly, but little is known about their involvement in immune cell signaling. Our biochemical data suggests that these proteins have functional relevance in some of the early and late events of the signaling cascade. In addition, I show that the GTPase dynamin 2, which is commonly associated with receptor endocytosis, is selectively recruited to the sites of receptor clustering. Protein knockdown of dynamin 2 decreases the accumulation of F-actin at the clustered receptors, implicating dynamin in the regulation of Fc[epsilon]RI mediated actin redistribution. These results point a possible role for dynamin-actin interactions in regulating activated IgEFc[epsilon]RI internalization.
