The interactions of cells with their surrounding extracellular
matrix (ECM) plays a pivotal role in driving normal cell behavior,
from development to tissue differentiation and function. At the
cellular level, organ homeostasis depends on a productive
communication between cells and ECM, which eventually leads to the
normal phenotypic repertoire that characterize each cell type in
the organism. A failure to establish these normal interactions and
to interpret the cues emanating from the ECM is one of the major
causes in abnormal development and the pathogenesis of multiple
diseases. To recognize and act upon the biophysical signals that
are generated by the cross talk between cells and ECM, the cells
developed specific receptors, among them a unique set of receptor
tyrosine kinases (RTKs), known as the Discoidin Domain Receptors
(DDRs). The DDRs are the only RTKs that specifically bind to and
are activated by collagen, a major protein component of the ECM.
Hence, the DDRs are part of the signaling networks that translate
information from the ECM, and thus they are key regulators of
cell-matrix interactions. Under physiological conditions, DDRs
control cell and tissue homeostasis by acting on collagen sensors;
transducing signals that regulate cell polarity, tissue
morphogenesis, cell differentiation, and collagen deposition. DDRs
play a key role in diseases that are characterized by dysfunction
of the stromal component, which lead to abnormal collagen
deposition and the resulting fibrotic response that disrupt normal
organ function in disease of the cardiovascular system, lungs and
kidneys, just to mention a few. In cancer, DDRs are hijacked by
tumor and stromal cells to disrupt normal cell-collagen
communication and initiate pro-oncogenic programs. Importantly,
several cancer types exhibit DDR mutations, which are thought to
alter receptor function, and contribute to cancer progression.
Therefore, the strong causative association between altered RTK
function and disease it is been translated today in the development
of specific tyrosine kinase inhibitors targeting DDRs for various
disease conditions. In spite of the accumulating evidence
highlighting the importance of DDRs in health and diseases, there
is still much to learn about these unique RTKs, as of today there
is a lack in the medical literature of a book dedicated solely to
DDRs. This is the first comprehensive volume dedicated to DDRs,
which will fill a gap in the field and serve those interested in
the scientific community to learn more about these important
receptors in health and disease.
This title highlights the current and topical areas of research in
this rapidly growing field. Expert authors from around the world
provide the latest insights into the mechanisms these fascinating
organisms use to survive.
Extensively revised and updated, the new edition of this valuable
reference work provides a comprehensive and up-to-date analysis of
the current knowledge and new research in Bacillus molecular and
cellular biology.
Flaviviruses are a diverse group of small RNA enveloped viruses,
many of which are important human and animal pathogens. The best
known include dengue virus, yellow fever virus, Japanese
encephalitis virus, and West Nile virus. These viruses are endemic
in many tropical and sub-tropical regions of the world. Dengue
virus alone infects over 100 million people annually. In recent
years, research on flaviviruses has progressed at a remarkable
rate, leading to significant advances in our understanding of virus
biology. This should ultimately lead to the development of better
vaccine and antiviral strategies. This up-to-date and cutting-edge
anthology contains contributions from the leading experts in the
flavivirus field. Chapters are balanced by contributions from
established investigators who have dedicated their careers to
flavivirus research with those from newcomers who have recently
made significant contributions to the flavivirus field. The book is
divided into two sections: Molecular Virology and Virus Prevention.
The first section on Molecular Virology covers: virion structure *
virus replication * the NS1 glycoprotein * the NS3 protein * the
NS5 protein * innate immunity and flavivirus infection * host
responses to flavivirus infection * flavivirus fitness and
transmission. The Virus Prevention section includes: vaccines *
antibody therapy * small molecule antiviral development *
flavivirus diagnostics * vector-virus interactions * vector
control. The book represents an important update of flavivirus
research and will serve as a reference to flavivirus researchers at
the graduate level and beyond. It is a recommended text for all
virology libraries.
One of the greatest public health achievements during the 20th
century was the dramatic reduction in the incidence of infectious
diseases due to the development of improved hygiene, vaccines, and
antimicrobial agents. However, new infectious diseases are emerging
and bacteria-induced illnesses - such as tuberculosis, whooping
cough, and typhoid fever - are still a major cause of global
mortality. In recent decades, the development of molecular biology
and genetic tools has led to extensive studies on the molecular and
cellular aspects of the virulence properties of pathogenic
bacteria. In this book, a group of distinguished scientists from
eight different countries and three continents, under the expert
guidance of the editors Camille Locht and Michel Simonet, overview
the molecular and cellular mechanisms of bacterial pathogenesis.
The 15 chapters are organized into five sections: a) approaches to
the study of bacterial pathogenesis; b) bacterial adhesion to the
cell surface and extracellular matrix of host tissues; c) poisoning
the host by toxins; d) cellular invasion by bacterial pathogens;
and e) bacterial evasion of host defenses. The book comprehensively
describe the most relevant and up-to-date information on pathogenic
features across the bacterial world. Aimed at the entire scientific
community from students to senior scientists and physicians,
Bacterial Pathogenesis is relevant to a broad range of people
interested in the mechanisms of bacterial infectious diseases and
is a recommended text for all microbiology laboratories.
As bacterial antibiotic resistance continues to exhaust the supply
of effective antibiotics, a global public health disaster appears
likely. Poor financial investment in antibiotic research has
exacerbated the situation. A call to arms - raised by several
prestigious scientific organizations a few years ago - rallied the
scientific community and now the scope of antibacterial research
has broadened considerably. Multi-disciplinary approaches have
yielded a wealth of new data on areas ranging from the
identification of novel antibacterial targets to the use of
biological agents for antibacterial therapy. In this book,
respected international experts summarize the most important
concepts and pioneering strategies currently being used to develop
novel antibacterials. The book opens with chapters on cellular
processes that could be used as novel antibacterial targets.
Examples include cell division, efflux pumps, metabolite-sensing
riboswitches, and bacterial secretion systems. These are followed
by excellent chapters on the identification of new, naturally
occurring antibacterial agents, including phage and
biosynthetically engineered compounds. Understanding the
host-microbe interaction and microbial communities and how they can
be exploited to develop new antibacterial strategies is discussed
in subsequent chapters. Other topics include antibacterial vaccines
adjuvants, host defense peptides, antibodies, within-host models,
and diagnostics.
Paramyxoviruses are a diverse family of non-segmented negative
strand RNA viruses that include many important human, animal, and
zoonotic pathogens. Despite their enormous importance, the nature
of the viral genome had proved an obstacle to research, with the
result that paramyxoviral research had lagged behind that of other
viruses. The advent of reverse genetics in recent years has changed
this, enabling great strides in the understanding of the genomics,
molecular biology, and viral pathogenesis. This book provides a
timely and comprehensive review of current knowledge of all
paramyxoviruses and is written by renowned scientists who have made
seminal contributions in their respective paramyxovirus fields of
expertise. Topics include: mumps virus * simian virus 5 *
parainfluenza viruses * Newcastle disease and related avian
paramyxoviruses * Sendai virus * Hendra virus * Nipah virus *
measles virus * canine distemper virus * rinderpest virus * peste
des petits ruminants virus * human respiratory syncytial virus *
metapneumoviruses * new and emerging paramyxoviruses. Each chapter
covers current knowledge on history, genome organization, viral
proteins, reverse genetics, epidemiology, pathogenesis, immunity,
diagnosis, prevention, and control and future challenges. This book
is an invaluable reference source of timely information for
virologists, microbiologists, immunologists, physicians,
veterinarians, and scientists working on paramyxoviruses. It is
also strongly recommended for all medical and veterinary school
libraries.
The revolutionary discovery of Helicobacter pylori started a new
era in the understanding and management of gastroduodenal diseases.
H. pylori is associated with chronic gastritis, peptic ulcers, MALT
lymphoma, the pathogenesis of gastric cancer and several
extra-gastric diseases. The organism displays an enormous genetic
diversity and some strains harbor numerous virulence factors. No
vaccines are available yet and increased antibiotic resistance of
the bacteria is of growing concern. Many questions about H. pylori
pathogenesis, epidemiology, prophylaxis, and treatment remain to be
answered. In addition, the role of non-pylori Helicobacter species
is becoming a topic of considerable medical interest. This book
highlights recent research and provides an up-to-date summary of
current knowledge for microbiologists, clinicians, and advanced
students working with Helicobacter. The contributors offer an
outstanding collection of reviews on many aspects of Helicobacter
research, including: microbiology * virulence factors * immunology
* vaccine research * epidemiology * diseases associated with the
infection * antibiotic resistance * treatment (including the use of
non-antibiotic agents). As a major reference volume on Helicobacter
pylori and how it impacts on public health worldwide, the book is
essential reading for those with an interest in the microbiology of
H. pylori and is recommended for all microbiology libraries.
Waterborne Pathogens: Detection Methods and Applications, Second
Edition, gives an overview of advanced and emerging technologies in
the detection of a range of waterborne pathogens. In addition, the
book presents existing methodologies, highlights where improvements
can be made, includes applications, and touches on the ways in
which new technologies can be applied in water management. Finally,
the book addresses issues of sample preparation (from sampling, to
concentration and enrichment), a key stage in any detection
protocol.
Interferons (IFNs) play pivotal roles in shaping the immune
responses in mammals and are particularly important for the control
of viral infections, cell growth, and immune regulation. These
proteins rapidly induce an anti-viral state in cells that surround
infected cells. In order to survive, viruses have evolved with
multiple strategies to evade the anti-viral effects of IFNs.
Elucidating the molecular and cellular biology of the
virus-interferon interaction is key to understanding issues, such
as viral pathogenesis, latency, and the development of novel
antivirals. In this book, international experts review current
research topics, producing a timely overview of this exciting
field. The book opens with a chapter that comprehensively reviews
the antiviral effects of extracellular double-stranded RNA - the
viral toxin. This is followed by chapters that review the
properties of type I and type III interferons, and the role of
interferon-stimulated genes. Additional chapters are devoted to
understanding the diverse strategies used by clinically-relevant
human viruses to subvert host interferon responses. The book closes
with an interesting overview of the clinical application of
interferons as antiviral and anticancer agents. It will be
essential reading for every scientist involved in interferon or
antiviral research and will be a recommended text for all virology
laboratories.
The hepatitis C virus (HCV) is a significant public health problem
of international importance. HCV is capable of establishing chronic
infections resulting in progressive liver damage and other
problems. Current drug therapies are ineffective, highlighting the
need for better antiviral drugs. Recent research in HCV genetics
and molecular biology have led to significant advances in our
understanding of the life cycle of this important pathogen and may
ultimately lead to better antiviral strategies. The editors of this
book have recruited experts from around the world to produce a
timely and well-compiled review of current HCV research, with an
emphasis on antiviral drug development. The chapters provide
in-depth reviews of the most critical areas of research. Topics
include: the HCV life cycle * HCV assays * HCV resources * HCV
databases * HCV infection systems * models of hepatitis C
infections * overview of the drug pipeline * clinical trial design
* clinical virology and drug development * NS3 protease inhibitors
* NS3-NS4A complex inhibitors * NS3 helicase inhibitors * NS4B
targets and inhibitors * NS5A inhibitors * nucleoside inhibitors *
NS5B polymerase inhibitors * glycoprotein-dependent entry * host
cell targets and inhibitors * innate immunity for HCV antiviral
therapy.
Alphaherpesviruses are a fascinating group of DNA viruses that
include important human pathogens, such as herpes simplex virus
type 1 (HSV-1), HSV-2, and varicella-zoster virus (VZV) - the
causative agents of cold sores, genital ulcerous disease, and
chickenpox/shingles, respectively. A key attribute of these viruses
is their ability to establish lifelong latent infection in the
peripheral nervous system of the host. Such persistence requires
subversion of the host's immune system and intrinsic antiviral
defense mechanisms. Understanding the mechanisms of the immune
evasion and what triggers viral reactivation is a major challenge
for today's researchers. This has prompted enormous research
efforts into understanding the molecular and cellular biology of
these viruses. This up-to-date and comprehensive study distills the
most important research in this area, providing a timely overview
of the field. Topics include: transcriptional regulation, DNA
replication, translational control, virus entry and capsid
assembly, the role of microRNAs in infection, and oncolytic vectors
for cancer therapy. In addition, there is coverage of virus-host
interactions, including apoptosis, subversion of host protein
quality control and DNA damage response pathways, autophagy,
establishment and reactivation from latency, interferon responses,
immunity, and vaccine development. This is essential reading for
everyone working with alphaherpesviruses and will be of interest to
all virologists working on latent infections.
