Book Description
Over the past half-century, the central dogma, in which DNA makes RNA makes protein, has dominated thinking in biology, with continuing refinements in understanding of DNA inheritance, gene expression, and macromolecular interactions. However, we have also witnessed the elucidation of epigenetic phenomena that violate conventional notions of inheritance. Protein-only inheritance involves the transmission of phenotypes by self-perpetuating changes in protein conformation. Proteins that constitute chromatin can also transmit heritable information, for example, via posttranslational modifications of histones. Both the transmission of phenotypes via the formation of protein conformations and the inheritance of chromatin states involve self-perpetuating assemblies of proteins, and there is evidence for some common structural features and conceptual frameworks between them. To foster interactions between researchers in these two fields, the National Academy of Sciences convened an Arthur M.Sackler Colloquium entitled "Self-Perpetuating Structural States in Biology, Disease, and Genetics" in Washington, DC, on March 22-24, 2002. Participants described new phenomenology and provided insights into fundamental mechanisms of protein and chromatin inheritance. Perhaps most surprising to attendees was emerging evidence that these unconventional modes of inheritance may be common.

Book Description
Microbial virulence factors encompass a wide range of molecules produced by pathogenic microorganisms, enhancing their ability to evade their host defenses and cause disease. This broad definition comprises secreted products such as toxins, enzymes, exopolysaccharides, as well as cell surface structures such as capsules, lipopolysaccharides, glyco- and lipoproteins. Intracellular changes in metabolic regulatory networks, governed by protein sensors/regulators and non-coding regulatory RNAs, are also known to contribute to virulence. Furthermore, some secreted microbial products have the ability to enter the host cell and manipulate their machinery, contributing to the success of the infection. The knowledge, at the molecular level, of the biology of microbial pathogens and their virulence factors is central in the development of novel therapeutic molecules and strategies to combat microbial infections. The present collection comprises state of the art research and review papers on virulence factors and mechanisms of a wide range of bacterial and fungal pathogens for humans, animals, and plants, thus reflecting the impact of microorganisms in health and economic human activities, and the importance of the topic.

Book Description
In recent decades, infectious diseases, once believed to be fairly contained, have become a vital, resurgent field of research. In Host-Pathogen Interactions: Methods and Protocols, top experts examine the relationship between the host and the pathogen, crucial in the outcome of an infection and the establishment of disease or asymptomatic, commensal colonization by organisms. The step-by-step laboratory methods and protocols of this volume study host-pathogen interaction, with a focus on fungal, bacterial and parasitic pathogens, at a molecular level in order to reveal the mechanisms of infection and to identify the vulnerabilities of the pathogen of interest. Written in the highly successful Methods in Molecular BiologyTM series format, the chapters feature brief subject introductions, lists of the necessary materials and reagents, and tips on troubleshooting and avoiding known pitfalls. Comprehensive and cutting-edge, Host-Pathogen Interactions: Methods and Protocols serves as an easy entry point for all those investigating the factors responsible for the pathogenicity of microorganisms.

Book Description
Infectious diseases have existed longer than us, as long as us, or are relatively newer than us. It may be the case that a disease has existed for many, many years but has only recently begun affecting humans. At the turn of the century the number of deaths caused by infections in the United States had been falling steadily but since the '80s has seen an increase. In the past 30 years alone 37 new pathogens have been identified as human disease threats and 12% of known human pathogens have been classified as either emerging or remerging. Whatever the story, there is currently a "war" on infectious diseases. This war is simply the systematic search for the microbial "cause" of each disease, followed by the development of antimicrobial therapies. The "war" on infectious diseases, however, must be revisited in order to develop a more realistic and detailed picture of the dynamic interactions among and between host organisms and their diverse populations of microbes. Only a fraction of these microbes are pathogens. Thus, in order to explore the crafting of a new metaphor for host-microbe relationships, and to consider how such a new perspective might inform and prioritize biomedical research, the Forum on Microbial Threats of the Institute of Medicine (IOM) convened the workshop, Ending the War Metaphor: The Changing Agenda for Unraveling the Host-Microbe Relationship on March 16-17, 2005. Workshop participants examined knowledge and approaches to learning about the bacterial inhabitants of the human gut, the best known host-microbe system, as well as findings from studies of microbial communities associated with other mammals, fish, plants, soil, and insects. The perspective adopted by this workshop is one that recognizes the breadth and diversity of host-microbe relationships beyond those relative few that result in overt disease. Included in this summary are the reports and papers of individuals participating in the Forum as well as the views of the editors.

Book Description
The growing body of information on bacteria pathogenic for humans, mammals and plants generated within the past ten years has shown the interesting conservation of newly identified genes that playa direct role in the pathogenic mechanism. In addition to these genes, there are also genes that confer host specificities and other traits important in pathogenesis on these pathogens. In this volume, we have organized the subject areas to best fit the concept on the way bacterial pathogens recognize, interact and invade the host, on the regulation of genes involved in virulence, on the genes involved in the elaboration of toxins and other pathogenic components such as iron sequestering proteins, and on the mechanisms of circumventing the host defense systems. These areas are divided into Sections. Section I covers the first step when the pathogen seeks its host, and Sections II through VI cover subsequent steps leading to pathogenesis while avoiding host defenses. We conclude this work with a chapter summarizing information on examples of virulence mechanisms that are highly conserved.
