Download or read book Biological DNA Sensor written by Jan Naujoks and published by Elsevier Inc. Chapters. This book was released on 2013-10-30 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: The detection of bacterial pathogens by the innate immune system is mediated by various pattern recognition receptors that sense microbial molecules such as cell wall components, virulence factors or nucleic acids. Bacterial DNA is recognized by Toll-like receptor 9 (TLR9) at endosomal compartments and by cyclic GMP-AMP synthase, polymerase III/RIG-I, AIM2-like receptors (ALRs), DNA helicases as well as other incompletely characterized proteins in the host cell cytosol. Depending on the receptor and specific engagement of the adapter molecules MyD88, STING, MAVS or ASC, sensing of bacterial DNA triggers expression of NF-κB-dependent proinflammatory genes, type I IFN responses, and/or inflammasome activation. Whereas inflammatory gene expression and inflammasome activation are required for an effective host defense to most bacterial infections, type I IFNs appear to play a regulatory role and can be beneficial or detrimental for the host. This chapter summarizes the current knowledge about the mechanisms of DNA sensing and its function in bacterial infections.

Download or read book The Inflammasomes written by Isabelle Couillin and published by Springer Science & Business Media. This book was released on 2011-07-02 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: The inflammasome was first described in 2002 as a molecular complex activating proinflammatory caspases and therefore regulating the maturation and biological activities of cytokines such as IL-1 and IL-18. This finding was substantiated by the identification of several mutations in the cias1 gene, encoding the human NLRP3 protein, responsible for several autoinflammatory disorders such as the Muckle Wells syndrome. Since, the interest for this complex has constantly increased and several inflammasome complexes with different specificities have been described. These inflammasomes sense a wide variety of pathogens and danger signals and are key players in the inflammatory response. With the contributions of leading international experts in the field, this book provides an extensive overview of the current knowledge of inflammasome biology and their role in health and disease.

Download or read book Biological DNA Sensor written by Tatsuya Saitoh and published by Elsevier Inc. Chapters. This book was released on 2013-10-30 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microbial double-stranded (ds)DNA potently stimulates innate immunity. Stimulator of interferon genes (STING) plays a major role in dsDNA-induced expression of type I interferons (IFNs) and elimination of invading pathogens. After stimulation, STING translocates from the endoplasmic reticulum to cytoplasmic punctate structures where it associates with TANK-binding kinase 1 (TBK1). TBK1 phosphorylates interferon regulatory factor 3 to induce type I IFNs and optineurin to induce autophagy, an intracellular clearance system. Autophagy-related protein, Atg9a, regulates membrane trafficking involved in STING movement and suppresses type I IFN expression. Absent in melanoma 2 (AIM2) plays a major role in dsDNA-induced inflammatory responses. After stimulation, AIM2 forms an inflammasome with an adaptor protein, ASC, and caspase-1, a protease, to induce the production of IL-1β, an inflammatory cytokine. Autophagy mediates degradation of activated AIM2-inflammasome to terminate the response. Thus, autophagy-related proteins, essential components of autophagy machinery, regulate innate immune responses induced by dsDNA.

Download or read book Biological DNA Sensor written by Surya Pandey and published by Elsevier Inc. Chapters. This book was released on 2013-10-30 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: DNA sensors initiate innate immune responses upon recognition of microbial and self-derived DNA in the intracellular compartments or cytoplasm. These sensors include TLR9, AIM2 like receptors and many other recently identified cytosolic DNA sensors. The otherwise protective nature of host defense by these receptors can turn hostile when they recognize self-DNA through various mechanisms and aberrantly activate DNA sensing pathways leading to unregulated or inappropriate type I IFN production and consequent autoimmune and autoinflammatory diseases. In this chapter, we highlight the current findings that shed light on the complex initiator and effector mechanisms that contribute to autoimmune disease pathology, including DNA sensing receptors, self and non-self discrimination, type I IFN system, mechanisms of enhanced self-DNA access to TLR9 and defective host DNA clearance.

Download or read book Biological DNA Sensor written by Sivapriya Kailasan Vanaja and published by Elsevier Inc. Chapters. This book was released on 2013-10-30 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: The innate immune response serves as the first line of defense against microbial infections by detecting pathogen-associated molecular patterns through germline-encoded pattern recognition receptors. Proteins of the PYHIN family have gained substantial research focus in recent years as central mediators of innate immune responses induced by cytosolic microbial DNA. Sensing of DNA by PYHINs typically leads to activation of inflammasomes and/or type I interferon responses that are crucial for host defense against invading pathogens. Certain members of the family are also involved in the development of autoimmune diseases as well as transcriptional regulation. Although the generation of knockout mice strains has unraveled the essential role of PYHIN proteins such as AIM2 in the development of antimicrobial innate immune responses, the exact biological role of several other PYHIN family members remains to be understood. This chapter reviews the important discoveries on PYHIN proteins and their role in microbial defense, autoimmunity and transcriptional regulation.

Numerous molecules participate in immune recognition, inhibition and activation, and these important immune molecules can be roughly divided into cell surface receptors, intracellular receptors and intracellular signaling molecules. The study of how these immune molecules function at molecular level has laid the foundation for understanding the immune system. The book provides researchers and students with the latest research advances concerning the structural biology of key immune molecules/pathways, and offers immunologists essential insights into how these immune molecules function.

Download or read book Molecular Biology of RNA written by David Elliott and published by Oxford University Press. This book was released on 2017-01-31 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: RNA plays a central, and until recently, somewhat underestimated role in the genetics underlying all forms of life on earth. This versatile molecule not only plays a crucial part in the synthesis of proteins from a DNA template, but is also intrinsically involved in the regulation of gene expression, and can even act as a catalyst in the form of a ribozyme. This latter property has led to the hypothesis that RNA - rather than DNA - could have played an essential part in the origin of life itself. This landmark text provides a systematic overview of the exciting and rapidly moving field of RNA biology. Key pioneering experiments, which provided the underlying evidence for what we now know, are described throughout, while the relevance of the subject to human disease is highlighted via frequent boxes. For the second edition of Molecular Biology of RNA, more introductory material has been incorporated at the beginning of the text, to aid students studying the subject for the first time. Throughout the text, new material has been included - particularly in relation to RNA binding domains, non-coding RNAs, and the connection between RNA biology and epigenetics. Finally, a new closing chapter discusses how exciting new technologies are being used to explore current topical areas of research.
