The human immunodeficiency virus type 1 (HIV-1) lifecycle is complex and the virus interacts with many host cellular proteins for productive replication. Mass spectrometry analysis is a powerful tool to identify cellular proteins important for HIV replication and pathogenesis. Prior proteomic studies demonstrate that HIV-1 infection perturbs the host cell proteome.

The development of proteomic analyses using advanced mass spectrometry techniques has revolutionized the way proteins are studied, namely, as individual molecules within a complex system. HIV-1 Proteomics: From Discovery to Clinical Application comprehensively covers protein analysis from the early classic experimental days to current state-of-the-art HIV-1 proteomics in a clear informative style that brings expert-level understanding to the novice. Discussion of important clinical applications and future directions for the field also make this an ideal read for the expert. After finishing this book, the reader will have a complete and functional understanding of protein analysis from traditional biochemistry to modern proteomics.

This volume summarizes recent advances in understanding the mechanisms of HIV-1 latency, in characterizing residual viral reservoirs, and in developing targeted interventions to reduce HIV-1 persistence during antiretroviral therapy. Specific chapters address the molecular mechanisms that govern and regulate HIV-1 transcription and latency; assays and technical approaches to quantify viral reservoirs in humans and animal models; the complex interchange between viral reservoirs and the host immune system; computational strategies to model viral reservoir dynamics; and the development of therapeutic approaches that target viral reservoir cells. With contributions from an interdisciplinary group of investigators that cover a broad spectrum of subjects, from molecular virology to proof-of-principle clinical trials, this book is a valuable resource for basic scientists, translational investigators, infectious-disease physicians, individuals living with HIV/AIDS and the general public.

The field of virology has seen explosive growth in the past few decades. A large amount of effort has gone into successfully delineating virus evolution, genetic diversity, immunology, pathogenesis, structure, vaccine development, viral gene expression and genomic replication strategies. In addition, considerable recent work has been focusing on cellular responses to infection as well as how viruses may induce transformation and oncogenesis. Viruses are obligate intracellular parasites and thus absolutely dependent upon host cells. Not surprisingly, they often cause profound changes in cells, including apoptosis, death and signalling, to name a few perturbations. Thus, the molecular signals for how viruses induce pathophysiological alterations in their hosts have been of growing recent interest. Cellular and organismal responses, such as those induced by virus infection, are invariably mediated by changes in gene and protein expression and modification. Thus, there has been keen interest in understanding how gene and protein expressions and modifications are quantitatively and qualitatively affected by such challenges. From a historical perspective, most early work that examined host protein responses to virus infection employed “biased” approaches, in which investigators targeted a limited number, or only one cellular molecule of interest. Completion of many organisms’ genome sequences has allowed the global “non-biased” simultaneous analysis of the entire repertoire of cellular mRNA species, the transcriptome, by gene micro-arrays. This has provided significant information about how cellular gene expressions are altered by virus-induced perturbations, but has not provided as much information about the encoded proteins. This results for several reasons, including, but not limited to the fact that gene expression levels cannot accurately predict protein expression levels, nor the types and extent of post-translational modifications, many genes encode multiple proteins through splice variants, and protein activity may be affected by a large number of conditions, including phosphorylation. Recent technological and bioinformatic approaches make it now possible to begin to extend similar global analyses to probe the cellular proteome, the repertoire of the actual effector molecules. One general strategy has been to take advantage of improved separations technologies, as well as greatly improved mass spectrometry resolution, to quantitatively or comparatively measure hundreds or thousands of proteins. Proteins from multiple conditions (i.e., mock-infected and infected) may be differentially labelled by various techniques, such as 2D-DIGE, ICAT, iTRAQ, SILAC, with 18O during peptide preparation, and/or by various other methods, and then compared to measure comparative alterations in the levels of proteins induced by the virus infection. Such analyses have also been extended by using “label-free” methods for more efficient multiplexing applications, and/or by examining specific protein modifications. In addition, concerted efforts to raise antibodies against all cellular proteins have resulted in the development of “antibody arrays,” which are also generally used for quantitative or comparative assays. Finally, while assays, such as the above, are generally limited to delineating the absolute amount of specific proteins, newer technologies have been developed that allow the simultaneous probing of hundreds of proteins’ functions. Assays, such as “Activity Based Protein Profiling”, are designed to probe enzymatic activity, with current focus on broad-spectrum proteases and other enzymatic classes. This Research Topic will provide an overview of many of these methods, as well as numerous specific examples of each approach, and how they are used to better delineate the ways viruses affect cellular responses during infection.

First, systems biology is an inter-disciplinary approach, requiring the combined talents of biologists, mathematicians, and computer scientists. Second, systems biology is holistic, with the goal of obtaining a comprehensive understanding of the workings of biological systems. This is achieved through the acquisition of massive amounts of data by high-throughput technologies—oligonucleotide microarrays, mass spectrometry, and next-generation sequencing—and the analysis of this data through sophisticated mathematical algorithms. It is perhaps the use of mathematics, to integrate abundant and diverse types of data and to generate models of interconnected molecular networks, that best characterizes systems biology.

The literature on recoding is scattered, so this superb book ?lls a need by prov- ing up-to-date, comprehensive, authoritative reviews of the many kinds of recoding phenomena. Between 1961 and 1966 my colleagues and I deciphered the genetic code in Escherichia coli and showed that the genetic code is the same in E. coli, Xenopus laevis, and guinea pig tissues. These results showed that the code has been c- served during evolution and strongly suggested that the code appeared very early during biological evolution, that all forms of life on earth descended from a c- mon ancestor, and thus that all forms of life on this planet are related to one another. The problem of biological time was solved by encoding information in DNA and retrieving the information for each new generation, for it is easier to make a new organism than it is to repair an aging, malfunctioning one. Subsequently, small modi?cations of the standard genetic code were found in certain organisms and in mitochondria. Mitochondrial DNA only encodes about 10–13 proteins, so some modi?cations of the genetic code are tolerated that pr- ably would be lethal if applied to the thousands of kinds of proteins encoded by genomic DNA.
