This volume offers an overview of the processes of zoonotic viral emergence, the intricacies of host/virus interactions, and the role of biological transitions and modifying factors.

In addition, there are in?uences that are extrinsic to potentially auto-reactive lymphocytes, including the function of regulatory cells, d- ferentiation state of antigen-presenting cells, availability of self-antigen, the cytokine and chemokine milieu, as well as the traf?cking patterns involved in generating productive immune interactions.

Adaptive immune responses serve as a key defense mechanism for the control of infections in vertebrates. Immune responses must be of sufficient strength to contain invading pathogens, antigen specific responses require regulatory mechanisms to ensure termination or downmodulation to avoid excessive damage to the host tissue.

Researchers have used a variety of techniques over the past century to gain fun- mental insights in the field of immunology and, as technology has advanced, so too has the ability of researchers to delve deeper into the biological mechanics of immunity.

This volume addresses the entire spectrum of challenges facing the nascent field of plant-based biomedical. This ranges from the selection of an appropriate production platform to specific methods of downstream processing and regulatory approval issues.

Measles virus, one of the most contagious of all human viruses, has been largely contained by the development and use of a vaccine that was introduced 50 years ago.

In the last few years the major effect that RNAi has had in invertebrate systems is beginning to take hold in mammalian systems through both single gene knockdown experiments and genome-scale screens. Through the introduction of RNAi, mammalian systems have finally gained admittance to the pantheon of model genetic systems.

This volume explores in detail the molecular biology, genetics and immunology of the bacterium Helicobacter pylori that causes serious gastric diseases such as gastric cancer. The book provides in-depth insights into the mechanisms of H. pylori-induced pathogenicity, gives an overview of how the bacterium colonizes the human gut, how it manages to persist in the body and which factors play a role in the development of H. pylori-induced gastric cancer. Furthermore, the interaction between the Gram-negative bacterium and the human gut microbiome is explored, and clinical management and treatment strategies to combat gastric cancer are discussed.Helicobacter pylori is an extremely successful pathogen that persistently colonizes the gut of about 50% of the world¿s population. H. pylori and its human host share a long co-evolutionary relationship that dates back for at least last 100,000 years and possibly longer. Infection by thisbacterium is a high-risk factor for the development of gastric diseases, including gastric cancer. Gastric cancer is associated with high morbidity and mortality and represents the 5th most common malignant tumour and the 4th leading cause of cancer-related death worldwide. H. pylori is the first bacterium that has been classified as a type-I carcinogen by the International Agency for Research on Cancer (IARC). Recent research progress identified crucial bacterial, host and environmental factors which control H. pylori-induced gastric malignancy. New studies also suggest that specific human germline mutations and other genetic aberrations have an important impact on H. pylori-induced pathology. In this volume, all these recently discovered mechanisms are reviewed in the light of gastric cancer development, and H. pylori epidemiology, virulence factors, immune evasion, pathophysiology, cancer signalling and novel therapeutic protocols are presented. This volume is aimed at researchers in the fields of immunology, genetics, microbiology and medicine who are interested in the detailed mechanisms of the pathogenicity of this carcinogenic stomach bacterium.

The structural and functional importance of the correct patterns of DNA methylation in all parts of a mammalian genome is not well understood. The stability, inheritability, and developmental flexibility of these patterns point to a major role that these patterns appear to play in determining structure and function of the genome.

The purpose of this review is to examine the potential role of molecular mimicry in the pathogenesis of human T-lymphotropic virus type 1 ((HTLV- 1)-associated myelopathy/tropical spastic paraparesis (HAM/TSP)). Comp- hensive reviews on the pathogenic mechanisms of HTLV-1-associated human diseases are available throughout the medical literature (Bangham 2000,, 2003; Barmak et al. 2003; Jacobson 2002; Levin and Jacobson 1997; Nagai and Osame 2003; Osame 2002). Approximately 25 years ago the ?rst human retrovirus, HTLV-1, was isolated (Poeisz et al. 1980). Subsequently, infection with HTLV-1 was shown to cause adult T-cell leukemia (ATL) and HAM/TSP (Gessain et al. 1985; McFarlin and Blattner 1991; Osame et al. 1986; Poeisz et al. 1980; Yoshida et al. 1987). HTLV-1 may infect up to 30% of people in endemic areas and 10-20 million people worldwide (Barmak et al. 2003; Edlich et al. 2000). However, only 1%-5% develop either ATL or HAM/TSP, the remainder being clinically asymptomatic carriers of HTLV-1 (Bangham 2000, 2003; Barmak et al. 2003; Jacobson 2002; Levin and Jacobson 1997; Nagai and Osame 2003; Osame 2002). Why infection with HTLV-1 causes ATL or HAM/TSP in some people while the vast majority of individuals are asymptomatic is largely - known. Some possible factors that may differentiate the asymptomatic from the diseased state include viral strain, human histocompatibility leukocyte antigen (HLA), viral load, and the immune response (Bangham 2000, 2003; Barmak et al. 2003; Jacobson 2002; Levin and Jacobson 1997; Nagai and Osame 2003; Nagai et al. 1998; Niewiesk et al. 1994; Osame 2002).

Apoptosis is a regulated, energy-dependent process by which a cell se- destructs. This mechanism of programmed cell death plays an important role in normal development and control of cell numbers in mature a- mals. Apoptosis was initially defined by morphological criteria to describe the distinctive appearance of dying cells that developed nuclear conden- tion, cell shrinkage, and cytoplasmic blebbing. Initiation of the apoptotic process can come from external or internal stimuli and is highly regulated both by molecules that facilitate and by molecules that inhibit the process. Common features of apoptosis include activation of proteases and - cleases, mitochondrial membrane permeabilization, chromatin disruption, and translocation of phosphatidylserine from the inner to the outer s- face of the plasma membrane. Apoptotic cells attract phagocytes that - gulf the apoptotic bodies and prevent tissue damage in the region. Intense investigation of the cell death process has defined many molecular features of the pathway by which regulation and execution can be exploited by pathogens.

This volume provides an overview of recent advances in our understanding of the biology of marburg- and ebolaviruses. It focuses on four essential areas: 1) ecology, outbreaks and clinical management, 2) disease, pathogenesis and protection, 3) virus replication inside the cell, and 4) molecular tools for virus study and taxonomy. For 50 years, these viruses have spilled over sporadically and without warning from their wildlife reservoirs, often causing major outbreaks and high fatalities. The consequences can be devastating, with a clear potential for global reach, as demonstrated by the 2013 West African outbreak of Ebola virus, which led to over 28,000 reported cases across three continents and more than 11,000 deaths. Given the international threat posed by these viruses, the pace and scope of basic research have also greatly intensified, ranging from studies of virus emergence, epidemiology, antiviral countermeasures and human disease to detailed mechanistic studies of virus entry, replication, virion assembly and protein structure. Written by internationally respected experts, this book will appeal to a wide audience and be a valuable resource for basic researchers, clinicians and advanced students alike.
