The concept of innate immunity refers to the first-line host defense that serves to limit infection in the early hours after exposure to microorganisms. Recent data have highlighted similarities between pathogen recognition, signaling pathways, and effector mechanisms of innate immunity in Drosophila and mammals, pointing to a common ancestry of these defenses. In addition to its role in the early phase of defense, innate immunity in mammals appears to playa key role in stimulating the subsequent clonal response of adaptive immunity. Recent exciting information has determined that the templates that are laid down in primitive life forms, like flowering plants and insects, form the basic prin...
This comprehensive treatise on the reticuloendothelial system is a project jointly shared by individual members of the Reticuloendothelial (RE) Society and bio medical scientists in general who are interested in the intricate system of cells and molecular moieties derived from those cells which constitute the RES. It may now be more fashionable in some quarters to consider these cells as part of what is called the mononuclear phagocytic system or the lymphoreticular sys tem. Nevertheless, because of historical developments and current interest in the subject by investigators from many diverse areas, it seems advantageous to present in one comprehensive treatise current information and knowle...
An accompanying volume (Volume 6) in this series presents strategies of cellular invasion from the viewpoint of the microbe.This filed of study is growing rapidly after a somewhat slow start over recent decades. This collection of invited chapters attempts to reflect current research, and brings together cell biologists, microbiologists and immunologists with disparate interests. However, there is a certain unity, even repetition of key themes, hopefully like a symphony rather than a boring catalogue. It will be evident that editorial bias favors intracellular paratism and medically important organisms. The neutrophil is far more than a supporting player to the macrophage, and some attempt is made to remind the reader of some of its unique skills. To retain a manageable size, the emphasis is on relatively early events such as mutual recognition, cell entry, and response, rather than on longterm changes in gene expression by either host cell or pathogen. Viruses are excluded not because of lack of importance but because of somewhat different research approaches, although it is cytogenes, share common strategies in invasion and intercellular spread.
In recent years increased scientific attention has been given to immediate defense mechanisms based on non-clonal recognition of microbial components. These mechanisms constitute the innate immunity arm of the body s defense. Identification of pathogens by these mechanisms involves primarily receptors recognizing sugar moieties of various microorganisms. Innate immunity based mechanisms are essential for the existence of multicellular organisms. They are evolutionarily conserved and designed to provide immediate protection against microbial pathogens to eradicate infection. Activation of innate immunity is crucial for transition to specific immunity and for its orientation, and to assist the...
Humans coexist with millions of harmless microorganisms, but emerging diseases, resistance to antibiotics, and the threat of bioterrorism are forcing scientists to look for new ways to confront the microbes that do pose a danger. This report identifies innovative approaches to the development of antimicrobial drugs and vaccines based on a greater understanding of how the human immune system interacts with both good and bad microbes. The report concludes that the development of a single superdrug to fight all infectious agents is unrealistic.
To address the exponential growth in the fields of pediatric hematology and oncology, this classic reference has been separated into two distinct volumes. With this volume, devoted strictly to pediatric hematology, and another to pediatric oncology, you’ll keep you on the cutting-edge of these two specialties. The completely revised 7th edition of Nathan and Oski’s Hematology of Infancy and Childhood is now in full color, and provides you with the most comprehensive, authoritative, up-to-date information for diagnosing and treating children with hematologic disorders. It brings together the pathophysiology of disease with detailed clinical guidance on diagnosis and management for the ful...
Reviews the latest research in the field for researchers and clinicians. After a general introduction to DNA base excision repair, chapters cover uracil DNA glycosylases, repair of oxidized purines in DNA, mammalian mismatch-specific DNA glycosylases, repair of apurinic/apyrimidic sites in DNA by AP endonucleases, mutagenesis of abasic sites, a pro
A concise clinical reference that facilitates the diagnosis of intrauterine and perinatally acquired infections was the goal in creating the Congenital and Perinatal Infections: A Concise Guide to Diagnosis. Information about the natural history, m- agement, and outcome of these infections is well detailed in many other sources and so has not been included. Rather, the focus of the book is diagnosis. The initial chapters provide general information about serological and nonserological assays that are used for the diagnosis of infections, and a chapter about the placenta includes details about histopathological findings that can be helpful with the diagnosis of congenital inf- tions. The rema...
