Lysozyme
Author: Elliott Osserman
Publisher: Elsevier
ISBN: 0323143679
Category : Science
Languages : en
Pages : 670
Book Description
Lysozyme contains the proceedings of the Lysozyme Conference held in New York on October 29-31, 1972 on the occasion of the 50th anniversary of the discovery of lysozyme by Sir Alexander Fleming. The papers explore the chemistry and structure of lysozymes, their interactions with substrates and inhibitors, and distribution in tissues. Changes associated with various disease states are also discussed, along with evidence indicating that lysozyme may significantly alter certain mammalian cell constituents. Comprised of 42 chapters, this book begins with an overview of the structure of various lysozymes, including avian and mammalian lysozymes. The use of X-ray crystallography for lysozyme analysis is also considered. Subsequent chapters focus on the structure of bacterial cell walls; affinity labeling of lysozyme; substrate requirements of glycosidases for lytic activity on bacterial walls; and the solution behavior of hen egg white and human lysozyme. The role of lysozyme in hematology and its relation to myeloperoxidase and lactoferrin are also examined, together with lysozyme measurements in acute leukemia; serum and urine lysozyme in sarcoidosis; lysozyme as a component of human cartilage; and agglutination of rat liver mitochondria by lysozyme. This monograph should be of interest to practitioners and researchers in the fields of biophysics, chemistry, microbiology, physiology, and clinical medicine.

Host and Microbe Adaptations in the Evolution of Immunity

ISBN: 2889630226

Languages : en
Pages : 254
Book Description
The evolution of metazoans has been accompanied by new interfaces with the microbial environment that include biological barriers and surveillance by specialized cell types. Increasingly complex organisms require increased capacities to confront pathogens, achieved by co-evolution of recognition mechanisms and regulatory pathways. Two distinct but interactive forms of immunity have evolved. Innate immunity, shared by all metazoans, is traditionally viewed as simple and non-specific. Adaptive immunity possesses the capacity to anticipate new infectious challenges and recall previous exposures; the most well-understood example of such a system, exhibited by lymphocytes of vertebrates, is based on somatic gene alterations that generate extraordinary specificity in discrimination of molecular structures. Our understanding of immune phylogeny over the past decades has tried to reconcile immunity from a vertebrate standpoint. While informative, such approaches cannot completely address the complex nature of selective pressures brought to bear by the complex microbiota (including pathogens) that co-exist with all metazoans. In recent years, comparative studies (and new technologies) have broadened our concepts of immunity from a systems-wide perspective. Unexpected findings, e.g., genetic expansions of innate receptors, high levels of polymorphism, RNA-based forms of generating diversity, adaptive evolution and functional divergence of gene families and the recognition of novel mediators of adaptive immunity, prompt us to reconsider the very nature of immunity. Even fundamental paradigms as to how the jawed vertebrate adaptive immune system should be structured for “optimal” recognition potential have been disrupted more than once (e.g., the discovery of the multicluster organization and germline joining of immunoglobulin genes in sharks, gene conversion as a mechanism of somatic diversification, absence of IgM or MHC II in certain teleost fishes). Mechanistically, concepts of innate immune memory, often referred to as “trained memory,” have been realized further, with the development of new discoveries in studies of epigenetic regulation of somatic lineages. Immune systems innovate and adapt in a taxon-specific manner, driven by the complexity of interactions with microbial symbionts (commensals, mutualists and pathogens). Immune systems are shaped by selective forces that reflect consequences of dynamic interactions with microbial environments as well as a capacity for rapid change that can be facilitated by genomic instabilities. We have learned that characterizing receptors and receptor interactions is not necessarily the most significant component in understanding the evolution of immunity. Rather, such a subject needs to be understood from a more global perspective and will necessitate re-consideration of the physical barriers that afford protection and the developmental processes that create them. By far, the most significant paradigm shifts in our understanding of immunity and the infection process has been that microbes no longer are considered to be an automatic cause or consequence of illness, but rather integral components of normal physiology and homeostasis. Immune phylogeny has been shaped not only by an arms race with pathogens but also perhaps by mutualistic interactions with resident microbes. This Research Topic updates and extends the previous eBook on Changing Views of the Evolution of Immunity and contains peer-reviewed submissions of original research, reviews and opinions.

Aquatic Genomics
Author: N. Shimizu
Publisher: Springer Science & Business Media
ISBN: 4431659382
Category : Science
Languages : en
Pages : 448
Book Description
In a scientific pursuit there is continual food for discovery and wonder. M. Shelley (1818) Genomic analysis of aquatic species has long been overshadowed by the superb activity of the human genome project. However, aquatic genomics is now in the limelight as evidenced by the recent accomplishment of fugu genome sequencing, which provided a significant foundation for comparative fish genomics. Undoubt edly, such progress will provide an exciting and unparalleled boost to our knowl edge of the genetics of aquatic species. Thus, aquatic genomics research has become a promising new research field with an impact on the fishery industry. It is notewor thy that the Food and Agriculture Organization (FAO) of the United Nations has projected that current global fisheries production will soon become insufficient to supply the increasing world population and that aquaculture has a great potential to fulfill that demand. This book, Aquatic Genomic. ~: Steps Toward a Great Future, was designed as a collection of advanced knowledge in aquatic genomics and biological sciences. It covers a variety of aquatic organisms including fish, crustaceans, and shellfish, and describes various advanced methodologies, including genome analysis, gene map ping, DNA markers, and EST analysis. Also included are discussions of many sub jects such as regulation of gene expression, stress and immune responses, sex differ entiation, hormonal control, and transgenic fishes.
