Abstract

Herpesviruses are unique among viruses as they encode for a complex self-regulatory system, aggressively invade and persist in the host, evade immune defense, alter all regulatory mechanisms of the macroorganism and modify the replication of heterologous viruses. Environmental factors influence these unconventional relationships. Consequently, a single herpesvirus species can be attributed to a wide range of diseases as etiological agents or cofactors. This book is intended to give an overview on selected clinical hot topics: herpes simplex virus encephalitis, persistent infection in the gingiva, thymidine kinase gene expression causing male infertility, and pharmaceutical reactivation of Epstein-Barr virus for oncolysis. Immune evasion mechanisms and new ways to formulate vaccines are exhaustively reviewed. Finally, a surprise: bovine herpesviruses could serve as models to study the pathomechanism of herpesviruses.

Abstract

The World Health Organization (WHO) estimates that 3-5 million cases of severe influenza worldwide will result in 250,000-500,000 deaths annually. Collectively, data are shared via the WHO's Global Influenza Surveillance and Response System (GISRS), which includes 143 institutions in 113 WHO member states, to help alert the emergence of antigenic variants or the beginning of a pandemic. In April 2009, the Centers for Disease Control and Prevention (CDC) cited the first incidence of human-to-human transmission of pandemic H1N1, also referred to as swine influenza A, which was antigenically distinct from other circulating human H1N1. As the first influenza pandemic of the twenty-first century, pandemic H1N1 was not included in the annual trivalent vaccine regimen, leaving a large majority of the population unprotected from the newly emerging pathogen.

Abstract

Malaria is still the main vector-borne parasitic disease in the world. Fortunately, elimination of this disease was achieved in multiple countries during the last decades. During the last decade, a significant reduction of malaria in the Americas was achieved. Nevertheless, many challenges still are ahead in order to reach a higher control and to continue in the elimination toward a world free of malaria in the next decades. This book tries to update the significant epidemiological and clinical research in many aspects with a multinational perspective. This book with 20 chapters is organized into 5 major sections: (I) Clinical and Epidemiological Aspects, (II) Basic Science, (III) Therapeutics and Antimalarials, (IV) Vaccines, and (V) Entomology and Vector Control.

Abstract

Genome-wide association studies (GWAS) for complex disorders with large case-control populations have been performed on hundreds of traits in more than 1200 published studies (http://www.genome.gov/gwastudies/) but the variants detected by GWAS account for little of the heritability of these traits, leading to an increasing interest in using family based designs. While GWAS studies are designed to find common variants with low to moderate attributable risks, family based studies are expected to find rare variants with high attributable risk. Because family-based designs can better control both genetic and environmental background, this study design is robust to heterogeneity and population stratification. Moreover, in family-based analysis, the background genetic variation can be modeled to control the residual variance which could increase the power to identify disease associated rare variants. Analysis of families can also help us gain knowledge about disease transmission and inheritance patterns. Although a family-based design has the advantage of being robust to false positives, novel and powerful methods to analyze families in genetic epidemiology continue to be needed, especially for the interaction between genetic and environmental factors associated with disease. Moreover, with the rapid development of sequencing technology, advances in approaches to the design and analysis of sequencing data in families are also greatly needed. The 11 articles in this book all introduce new methodology and, using family data, substantial new findings are presented in the areas of infectious diseases, diabetes, eye traits, autism spectrum disorder and prostate cancer.

Abstract

The goal of this research topic was to gather current knowledge on the interaction of bacterial exotoxins and effector proteins with the host immune system. The following 16 research and review articles in this special issue describe mechanisms of immune modification and evasion and provide an overview over the complexity of bacterial toxin interaction with different cells of the immune system.
