Book Description
The proper physiological functioning of most eukaryotic cells requires their assembly into multi-cellular tissues that form organized organ systems. Cells of the immune system develop in bone marrow and lymphoid organs, but as the cells mature they leave these organs and circulate as single cells. Antigen receptors (TCRs) of T cells search for membrane MHC proteins that are bound to peptides derived from infectious pathogens or cellular transformations. The detection of such speci?c peptide–MHC antigens initiates T cell activation, adhesion, and immune-effectors functions. Studies of normal and transformed T cell lines and of T cells from transgenic mice led to comprehensive understanding of the mole- lar basis of antigen-receptor recognition and signaling. In spite of these remarkable genetic and biochemical advances, other key physiological mechanisms that par- cipate in sensing and decoding the immune context to induce the appropriate cellular immune responses remain unresolved. TCR recognition is tightly regulated to trigger sensitive but balanced T cell responses that result in the effective elimination of the pathogens while minimizing collateral damage to the host. The sensitivity of TCR recognition has to be properly tempered to prevent unintended activation by self-peptide–MHC complexes that cause autoimmune diseases. It is likely that once the TCR is engaged by a peptide– MHC and TCR signaling begins, additional regulatory mechanisms, involving other receptors, would increase the ?delity of the response.

Book Description
Structural Biology in Immunology, Structure/Function of Novel Molecules of Immunologic Importance delivers important information on the structure and functional relationships in novel molecules of immunologic interest. Due to an increasingly sophisticated understanding of the immune system, the approach to the treatment of many immune-mediated diseases, including multiple sclerosis, systemic lupus erythematosus, rheumatoid arthritis, and inflammatory bowel disease has been dramatically altered. Furthermore, there is an increasing awareness of the critical role of the immune system in cancer biology. The improved central structure function relationships presented in this book will further enhance our ability to understand what defects in normal individuals can lead to disease. - Describes novel/recently discovered immunomodulatory proteins, including antibodies and co-stimulatory or co-inhibitory molecules - Emphasizes new biologic and small molecule drug design through the exploration of structure-function relationship - Features a collaborative editorial effort, involving clinical immunologists and structural biologists - Provides useful and practical insights on developing the necessary links between basic science and clinical therapy in immunology - Gives interested parties a bridge to learn about computer modeling and structure based design principles

Book Description
T cells play a vital role mediating adaptive immunity, a specific acquired resistance to an infectious agent produced by the introduction of an antigen. There are a variety of T cell types with different functions. They are called T cells, because they are derived from the thymus gland. This volume discusses how T cells are regulated through the operation of signaling mechanisms. Topics covered include positive and negative selection, early events in T cell receptor engagement, and various T cell subsets.

Book Description
The immunological synapse (IS) is a specialised cell-cell adhesion that mediates antigen acquisition and regulates the activation of lymphocytes. Initial studies of the IS showed a structure composed of stable supra-molecular activation clusters (SMAC) organised during the interaction of helper T lymphocytes with B lymphocytes, working as antigen presenting cells. A central SMAC of coalesced T cell receptors (TCRs) and a peripheral SMAC for cell-cell adhesion were observed. IS with similar structure was later described during antigen acquisition by B cells and during the interaction of NK cells with target and healthy cells. More recent research developed with microscopy systems that improve the spatial and temporal resolution has showed the complex molecular dynamics at the IS that governs lymphocyte activation. Currently, the IS is seen as a three-dimensional structure where signalling networks for lymphocyte activation and endosomal and cytoskeleton machinery are polarised. A view has emerged in which dynamic microclusters of signalling complexes are composed of molecular components attached to the plasma membrane and other components conveyed on sub-synaptic vesicles transported to the membrane by cytoskeletal fibers and motor proteins. Much information is nonetheless missing about how the dynamics of the endosomal compartment, the cytoskeleton, and signalling complexes are reciprocally regulated to achieve the function of lymphocytes. Experimental evidence also suggests that the environment surrounding lymphocytes exposed to different antigenic challenge regulates IS assembly and functional output, making an even more complex scenario still far from being completely understood. Also, although some signalling molecular components for lymphocyte activation have been identified and thoroughly studied, the function of other molecules has not been yet uncovered or deeply characterised. This research topic aims to provide the reader with the latest information about the molecular dynamics governing lymphocyte activation. These molecular dynamics dictate cell decisions. Thus, we expect that understanding them will provide new avenues for cell manipulation in therapies to treat different immune-related pathologies.

Book Description
This volume takes a closer look how the cell organelles Golgi apparatus (also known as the Golgi complex or Golgi body), and centriole are structurally and functionally intertwined. Initially, it was believed that the role of Golgi complex is limited to the packaging and preparation for secretion of various cellular proteins, while the centriole participates in cell division and cilia formation. However, since their discovery nearly 200 years ago, it became clear that these two organelles are interacting, and that their functions are much more complex and far reaching than previously thought. Recent findings indicate that the Golgi–Centriole relationship may be important for directional protein transport, cell polarization and cell cycle progression. Current studies indicate that Golgi and centriole also participate in development and act as cellular and immunological sensors, and that their abnormalities lead to cell and developmental abnormalities, Alzheimer, cancer, various lipid disorders and neurological and immunological diseases in humans. This volume combines the latest information on the structure, molecular composition, and roles of Golgi and centriole in various cellular functions and diseases. The better understanding of the Golgi–centriole interactions may lead to the development of novel therapies for the treatment of various diseases, including cancer.
