Macrophages secrete interferons (IFNs), as well as other inflammatory cytokines, following stimulation with lipopolysaccharide (LPS), the outer membrane component of Gram negative bacteria that has been implicated as the initiator of the sepsis-associated Systemic Inflammatory Response Syndrome (SIRS). The interferon regulatory factors (IRFs) comprise a family of DNA binding proteins that positively and negtively regulate transcription of IFN and certain IFN-inducible genes. Basal and LPS-inducible levels of mRNA expressed by three IRF family member genes, i.e., IRF-1, IRF-2, and ICSBP, as well as a panel of other well characterized, SIRS-associated, inflammatory genes, were analyzed in macrophages derived from fully LPS-responsive mouse strains (Lps(n)), genetically LPS-hyporesponsive (Lps(d)) mice, IRF-1 and IRF-2 'knockout' mice, as well as from Lpsn macrophages rendered 'endotoxin tolerant' in vitro. Our results suggest that the IRF nuclear binding proteins, as well as serine/threonine phosphatases, play important roles in LPS-induced gene expression and may provide novel targets for therapeutic intervention, not only in Gram negative sepsis, but also in other syndromes characterized by inflammatory mediator excess.

The second edition of this encyclopedia presents over 400 biologically important signaling molecules and the content is built on the core concepts of their functions along with early findings written by some of the world’s foremost experts. The molecules are described by recognized leaders in each molecule. The interactions of these single molecules in signal transduction networks will also be explored. This encyclopedia marks a new era in overview of current cellular signaling molecules for the specialist and the interested non-specialist alike. Currently, there are more than 30,000 genes in human genome. However, not all the proteins encoded by these genes work equally in order to maintain homeostasis. Understanding the important signaling molecules as completely as possible will significantly improve our research-based teaching and scientific capabilities.

Biological DNA Sensor defines the meaning of DNA sensing pathways and demonstrates the importance of the innate immune responses induced by double stranded DNA (dsDNA) through its influencing functions in disease pathology and immune activity of adjuvants for vaccines. Though discussed in specific subsections of existing books, dsDNA and its immunogenic properties has never received the complete treatment given in this book. Biological DNA Sensor approaches the impact of dsDNA's immunogenicity on disease and vaccinology holistically. It paints a complete and concise picture on the topic so you can understand this area of study and make more informed choices for your respective research needs. Chapters are authored by researchers who are renowned for their research focus, ensuring that this book provides the most complete views on the topics. - Multi-authored by a distinguished panel of world-class experts - Ideal source of information for those wanting to learn about DNA sensing - Provides in-depth explanations of DNA sensing pathways and the innate immune system, bridging the gap between them

Most of the diseases of modern mankind involve either acute or chronic inflammation. Measuring Immunity integrates the current information available on biomarkers and surrogate assays into a single handbook. It highlights the principles behind various applications, gives a brief summary on how they are conducted and provides detailed and critical analyses of murine models of immunity, clinical trials, and tests to predict utility and benefit. Measuring Immunity is indispensable for scientists and clinicians interested in the clinical applications of modern immunobiology.* Defines which assays of immune function are helpful in the assessment of clinical disorders involving inflammation and immunity* Assesses the dynamics of cellular and soluble factors in the peripheral blood using modern techniques * Includes basic science foundations as well as the approaches currently applied

Nitric oxide (NO) is a gas that transmits signals in an organism. Signal transmission by a gas that is produced by one cell and which penetrates through membranes and regulates the function of another cell represents an entirely new principle for signaling in biological systems. NO is a signal molecule of key importance for the cardiovascular system acting as a regulator of blood pressure and as a gatekeeper of blood flow to different organs. NO also exerts a series of other functions, such as acting a signal molecule in the nervous system and as a weapon against infections. NO is present in most living creatures and made by many different types of cells. NO research has led to new treatments for treating heart as well as lung diseases, shock, and impotence. Scientists are currently testing whether NO can be used to stop the growth of cancerous tumors, since the gas can induce programmed cell death, apoptosis. This book is the first comprehensive text on nitric oxide to cover all aspects--basic biology, chemistry, pathobiology, effects on various disease states, and therapeutic implications. - Edited by Nobel Laureate Louis J. Ignarro, editor of the Academic Press journal, Nitric Oxide - Authored by world experts on nitric oxide - Includes an overview of basic principles of biology and chemical biology - Covers principles of pathobiology, including the nervous system, cardiovascular function, pulmonary function, and immune defense
