Pathways for Cytolysis by Gillian M. Griffiths,Jürg Tschopp Pdf

At first glance the destruction of a target cell by a killer cell seems to be a simple endeavor. A closer look, however, reveals the complex mechanisms underlying this task. Killer cells are able to specifically recognize altered or infected cells. A transient contract with target cells has to be established to allow the delivery of lethal molecules or signals. The killer cell then disengages from the damaged cell and moves away to kill other target cells. After the eradication of the target cells, the number or activity of activated killer cells has to be reduced to avoid nonspecific killing of innocent cells. In 1992, Herman Eisen concluded, in his introductory remarks in the most recent volume on lymphocyte cytotoxicity (EISEN 1993): "Given the immense amount of effort made in the past decade to understand these (lytic) mechanisms, it seems surprising that a consensus about the principal mechanisms has not been reached." Since that time, advances made in the field of cell-mediated cytolysis are so significant that our knowledge regarding the lytic mechanisms has been considerably augmented. Much of this is due to studies with transfectants and mutants-either naturally occurring or generated by gene targeting. It is now clear that there are two predominant pathways which act hand in hand and lead to efficienttarget cell destruction.

Immunology, Immunopathology, and Immunity by Stewart Sell Pdf

The sixth edition of this best-selling textbook presents a systematic account of the effects, both good and bad, of the immune system. Special emphasis is placed on what the immune system actually does in causing and preventing disease. Divided into two parts, the sixth edition discusses inflammation, the fundamentals of the immune system and how it is activated, the seven immune effector mechanisms, and how these effector mechanisms act not only to protect against infection and cancer but also to cause diseases. Valuable reading for physicians, medical students, graduate students, nurse practitioners, physician assistants, teachers of immunology, and advanced courses in immunology.

Adverse Effects of Vaccines by Institute of Medicine,Board on Population Health and Public Health Practice,Committee to Review Adverse Effects of Vaccines Pdf

In 1900, for every 1,000 babies born in the United States, 100 would die before their first birthday, often due to infectious diseases. Today, vaccines exist for many viral and bacterial diseases. The National Childhood Vaccine Injury Act, passed in 1986, was intended to bolster vaccine research and development through the federal coordination of vaccine initiatives and to provide relief to vaccine manufacturers facing financial burdens. The legislation also intended to address concerns about the safety of vaccines by instituting a compensation program, setting up a passive surveillance system for vaccine adverse events, and by providing information to consumers. A key component of the legislation required the U.S. Department of Health and Human Services to collaborate with the Institute of Medicine to assess concerns about the safety of vaccines and potential adverse events, especially in children. Adverse Effects of Vaccines reviews the epidemiological, clinical, and biological evidence regarding adverse health events associated with specific vaccines covered by the National Vaccine Injury Compensation Program (VICP), including the varicella zoster vaccine, influenza vaccines, the hepatitis B vaccine, and the human papillomavirus vaccine, among others. For each possible adverse event, the report reviews peer-reviewed primary studies, summarizes their findings, and evaluates the epidemiological, clinical, and biological evidence. It finds that while no vaccine is 100 percent safe, very few adverse events are shown to be caused by vaccines. In addition, the evidence shows that vaccines do not cause several conditions. For example, the MMR vaccine is not associated with autism or childhood diabetes. Also, the DTaP vaccine is not associated with diabetes and the influenza vaccine given as a shot does not exacerbate asthma. Adverse Effects of Vaccines will be of special interest to the National Vaccine Program Office, the VICP, the Centers for Disease Control and Prevention, vaccine safety researchers and manufacturers, parents, caregivers, and health professionals in the private and public sectors.

Cytokine Storm Syndrome by Randy Q. Cron,Edward M. Behrens Pdf

Cytokine Storm Syndromes, including HLH and MAS, are frequently fatal disorders, particularly if not recognized early and treated during presentation. The genetics of Cytokine Storm Syndromes are being defined with many of the risk alleles giving rise to mutations in the perforin-mediated cytolytic pathway used by CD8 cytotoxic T cells and natural killer cells. These are being studied using murine models. Up to 10% of the general population may carry risk alleles for developing Cytokine Storm Syndromes, and Cytokine Storm Syndromes are being increasingly recognized around the world in pediatric and adult hospitals. A variety of infectious, rheumatic, and oncologic triggers are commonly associated with Cytokine Storm Syndromes, but understanding this disorder is critical for all researchers and physicians to ensure timely and appropriate therapy. This textbook, the first of its kind, addresses all aspects of the disorder – from genetics, pathophysiology, and ongoing research, to clinical presentations, risk factors, and treatment.

The Antigens by Michael Sela Pdf

The Antigens, Volume III is a comprehensive treatise covering all aspects of antigens, including their chemistry and biology as well as their immunologic role and expression. Topics covered range from microbial polysaccharides and lymphocytic receptors for antigens to antigenic determinants and antibody-combining sites. Allergens and the genetics of allergy are also explored. Comprised of seven chapters, this volume begins with a review of microbial polysaccharides as antigens, followed by a discussion on antigenic determinants and their specific reaction with antibody-combining sites. The reader is then introduced to the reaction of antigens with their specific receptors on lymphocytes. The next four chapters are concerned with several categories of more complex antigens which, in most cases, have yet to be characterized adequately at a molecular level: allergens, histocompatibility antigens, antigens of Mycoplasmatales and chlamydiae, and animal viruses. The book concludes with an analysis of virus infections and the immune responses they elicit. This monograph will be of interest to practitioners and researchers in immunology, experimental and clinical medicine, biochemistry, and other disciplines.

Effects of cell interactions at the endothelium in leukocyte differentiation and polarization during inflammation by Alain Haziot,Dan Jane-wit,Efstathios G. Stamatiades Pdf

A complex exchange of signals between endothelial cells and tissues occurs during steady-state and in inflammatory conditions. These interactions involve numerous cell types including an active contribution from endothelial cells and occur on both sides of the endothelial monolayer. In addition to functioning as selective permeability barriers, it is increasingly recognized that local cell attraction to endothelial cells provides the potential for focal interactions between relevant cells. In this context, cellular interactions taking place at the surface of the endothelium and within the perivascular spaces are thought to initiate crucial steps in the generation and shaping of immune responses. Blood elements (such as leukocytes, platelets, and vesicles) converge to the barrier formed by the endothelium where perivascular (such as macrophages, pericytes) initiate, convey, and/or amplify signals revealing tissue status. The innate and adaptative functions of endothelial cells themselves together with the immune functions of assembled cells at a focal point in capillaries create the potential for exchange of signals and dynamic fine tuning of responses through cell programming and cell selection. The resulting immune response may range from inadequate immunity and/or exhaustion to excess tissue destruction and fibrosis. Productive inflammation and its resolution are critically reliant on which cells are recruited and in which order, their state of activation, and interactions between recruited cells. Tissue-dependent signals further shape the recruitment of leukocytes to the endothelium. In the kidney for instance, in the presence of immune complexes, perivascular resident macrophages located in subendothelial spaces coupled with endothelial cells induce monocyte and neutrophil tissue infiltration, operating therefore as an anatomical and functional unit. The goals of this Research Topic are (i) to analyze how signal integration and partnering of cell types in transendothelial migration contribute to the development of tissue inflammation and how responses are geared towards specific profiles of reactions to injury; (ii) how the interplay between cell types including, but not limited to, endothelial cells, monocytes, resident macrophages, and T and B cells dynamically governs the immune responses that take place in the tissue; (iii) in which way do integrative capacities of endothelial and subendothelial cells shape and coordinate the successive recruitment of leukocyte populations.

Molecular Regulation of Endocytosis by Brian Ceresa Pdf

Molecular Regulation of Endocytosis is a compilation of scientific "short stories" about the entry of external substances into cells. As one can see from the chapters, endocytosis regulates diverse processes such as homeostasis of the cell, signal transduction, entry of pathogens and viruses. In addition to the experimental techniques embedded in each chapter, entire chapters are dedicated to experimental approaches that will be useful to all scientists and their model systems. For those more clinically oriented, the final chapters look to the future and ways of utilizing endocytic pathways for therapeutic purposes.

Cytolytic Lymphocytes and Complement Effectors of the Immune System by Eckhard R. Podack Pdf

These volumes, Cytolytic Lymphocytes and Complement: Effectors of the Immune System, originate from the realization that pathways of recognition and killings of foreign targets follow similar routes in the humoral and cellular part of the immune system. In particular, the homology of immunoglobins with the T-cell-MHC-antigen receptor at the beginning of the recognition sequence and the homology of complement component C9 with lymphocyte perforin 1 (P1) as pore formers at the end of the effector sequence are striking examples.
