This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Porcine reproductive and respiratory virus (PRRSV) is a pathogen of high importance in the porcine industry because it can lead to significant economic losses. One of the cell lines routinely used for research and vaccine production is MARC-145 (African green monkey kidney cells). Molecular interactions between the host cells and the virus are essential to understand how the virus uses the cell machinery to replicate and infect neighbouring cells. Our goal was to analyze the proteomic changes involved during the PRRSV infection in MARC-145 cells, including the composition of the infected cells' virions and exosomes. The infected and non-infected cells' supernatants were purified to obtain the host cells' virions and exosomes. Extracted proteins were further analyzed by High-Resolution-Quadrupole-Hybrid-Orbitrap mass spectrometry and classified according to molecular function and subcellular localization. The need for obtaining reliable proteomics data led to the next goal of optimizing the infection of MARC-145 cells with PRRSV. To assess the efficiency of the infection, we synchronized the infection, used a virus tagged with an enhanced green fluorescent protein (EGFP) and added polycations at different concentrations to stimulate the binding of the viral particles to the cell. To verify the percentage of infected cells, we used fluorescence microscopy and flow cytometry. Our findings suggest the cellular proteins affected during the PRRSV infection could play important roles in host immune response and/or the viral life cycle. The efficiency of the use of polycations was demonstrated to be effective in increasing PRRSV infection.
Download or read book Decoding Protein Networks During Porcine Epidemic Diarrhea Virus PEDV Infection Through Proteomics written by Camila Andrea Valle-Tejada and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Porcine epidemic diarrhea virus (PEDV) is responsible for severe economic losses. The PEDV epidemics have destroyed more than 10% of the US swine population in the past 3 years. Unfortunately, the insufficient understanding of virus-host interactions impedes the development of an effective vaccine against PEDV. Virus-host interactions are highly dynamic and may involve multiprotein complexes. Growing evidence indicates that extracellular microvesicles (EMV) and composition of the viral particles play an important role in viral pathogenesis and modulation of host immune responses to infection. Additionally, it could be expected that the composition of porcine epidemic diarrhea (PED) virions is cell type dependent, due to the differential incorporation or association of host cell proteins into or with virions. Consequently, the characterization of the proteomic profiles of the EMV, produced by the PEDV-infected cells, and identification of the host proteins that are specifically encapsidated into the virions are important for our further understanding of virus-host interactions. To accomplish this objective, we produced and purified PEDV virions and EMV and analyzed their protein composition using a proteomic approach. In order to investigate the spatial-temporal regulation of viral infection and due to the low overall infectivity of the virus, a certain optimization of the PEDV infection was needed. To this end, we synchronized and increased virus entry into the cells. This allowed us to study the proteomic patterns of the PEDV-infected cells in a time-resolved mode. We found that PEDV infection affected the abundance of various host proteins associated with microvesicles produced by the infected cells. More precisely, our proteomic data revealed that proteins involved in nucleic acids binding, metabolic processes and immune response pathways were among the most affected by the PEDV infection. Interestingly, host proteins involved in cell cycle regulation and cytoskeletal system also were affected in abundance, which is not surprising since several investigators have reported that cytoskeletal proteins are actively participating in moving the viral components to the assembly site, and that many viruses manipulate DNA repair and cell cycle. The present study has demonstrated the incorporation of numerous cellular proteins into the PED virions. Additionally, we demonstrated that treatment of PEDV virions with polycations (positively charged molecules) induced a nine-fold increase in the efficiency of viral entry and infection. Thus, polycations can be used for the optimization of PEDV infection and improved vaccine production. To the best of our knowledge, this is the first study of the composition of PED virions and microvesicles produced by PEDV infection.
Download or read book Recoding Expansion of Decoding Rules Enriches Gene Expression written by John F. Atkins and published by Springer Science & Business Media. This book was released on 2010-03-10 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2008-11-24 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: Achievements and progress in genome mapping and the genomics of microbes supersede by far those for higher plants and animals, in part due to their enormous economic implication but also smaller genome size. In the post-genomic era, whole genome sequences of animal-associated microbes are providing clues to depicting the genetic basis of the complex host-pathogen relationships and the evolution of parasitism; and to improving methods of controlling pathogens. This volume focuses on a globally important group of intracellular prokaryotic pathogens which affect livestock animals. These include Brucella, Mycobacterium, Anaplasma and Ehrlichia, as well as the protozoan pathogens Cryptosporidium and Theileria, for which genome sequence data is available. Insights from comparative genomics of the microbes described provide clues to the adaptation involved in host-microbe interactions, as well as resources potentially useful for application in future research and product development.

Download or read book Discovering Life Manufacturing Life written by Pierre V. Vignais and published by Springer Science & Business Media. This book was released on 2010-06-21 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Francis BACON, in his Novum Organum, Robert BOYLE, in his Skeptical Chemist and René DESCARTES, in his Discourse on Method; all of these men were witnesses to the th scientific revolution, which, in the 17 century, began to awaken the western world from a long sleep. In each of these works, the author emphasizes the role of the experimental method in exploring the laws of Nature, that is to say, the way in which an experiment is designed, implemented according to tried and tested te- niques, and used as a basis for drawing conclusions that are based only on results, with their margins of error, taking into account contemporary traditions and prejudices. Two centuries later, Claude BERNARD, in his Introduction to the Study of Experimental Medicine, made a passionate plea for the application of the experimental method when studying the functions of living beings. Twenty-first century Biology, which has been fertilized by highly sophisticated techniques inherited from Physics and Chemistry, blessed with a constantly increasing expertise in the manipulation of the genome, initiated into the mysteries of information techn- ogy, and enriched with the ever-growing fund of basic knowledge, at times appears to have forgotten its roots.

Download or read book Temporomandibular Disorders written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2020-07-01 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Temporomandibular disorders (TMDs), are a set of more than 30 health disorders associated with both the temporomandibular joints and the muscles and tissues of the jaw. TMDs have a range of causes and often co-occur with a number of overlapping medical conditions, including headaches, fibromyalgia, back pain and irritable bowel syndrome. TMDs can be transient or long-lasting and may be associated with problems that range from an occasional click of the jaw to severe chronic pain involving the entire orofacial region. Everyday activities, including eating and talking, are often difficult for people with TMDs, and many of them suffer with severe chronic pain due to this condition. Common social activities that most people take for granted, such as smiling, laughing, and kissing, can become unbearable. This dysfunction and pain, and its associated suffering, take a terrible toll on affected individuals, their families, and their friends. Individuals with TMDs often feel stigmatized and invalidated in their experiences by their family, friends, and, often, the health care community. Misjudgments and a failure to understand the nature and depths of TMDs can have severe consequences - more pain and more suffering - for individuals, their families and our society. Temporomandibular Disorders: Priorities for Research and Care calls on a number of stakeholders - across medicine, dentistry, and other fields - to improve the health and well-being of individuals with a TMD. This report addresses the current state of knowledge regarding TMD research, education and training, safety and efficacy of clinical treatments of TMDs, and burden and costs associated with TMDs. The recommendations of Temporomandibular Disorders focus on the actions that many organizations and agencies should take to improve TMD research and care and improve the overall health and well-being of individuals with a TMD.
