Download or read book Protective Immune Response to Dengue Virus Infection and Vaccines perspectives from the field to the bench written by Simona Zompi and published by Frontiers Media SA. This book was released on 2015-04-14 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dengue is the most important mosquito-transmitted viral disease in humans. Half of the world population is at risk of infection, mostly in tropical and sub-tropical areas. The World Health Organization (WHO) estimates that 50 to 100 million infections occur yearly, with 50,000 to 100,000 deaths related to dengue, mainly in children. Recent estimates show higher numbers, up to three times more, with 390 million estimated dengue infections per year, among which 96 million apparent infections (Bhatt et al. 2013). Initially localized to South-East Asia, dengue virus (DENV) started its spread in Latin America in the 80’s. Little is known about DENV spread in Africa, but multiple seroprevalence surveys over several years are now clearly showing endemic areas in East and West Africa (Brady et al. 2013). Finally, due to global warming and intense traveling there is a risk of global spread towards more temperate regions, and both US Key islands (FL) and southern Europe recently faced DENV outbreaks. There are currently no specific treatments or vaccines available. Even though several dengue vaccines are in the pipeline, clear correlates of protection are still lacking. The recent failure of the live-attenuated Sanofi vaccine Phase 2b trial (Sabchareon et al. 2013) and the lack of correlation between clinical protection and in vitro neutralization assays, clearly underlines the necessity to better understand the role of the different components of the immune system in protection against dengue virus infection and the requirement for the development of additional and/or improved predictive assays. The aim of this research topic is to provide novel data, opinions and literature reviews on the best immune correlates of protection and recent advances in the immune response to DENV infection that can allow rapid progress of dengue vaccines. Authors can choose to submit original research papers, reviews or opinions on pre-clinical or clinical observations that will help unify the field, with perspectives from epidemiology, virology, immunology and vaccine developers. This research topic will discuss different aspects of the protective immune response to DENV that can influence vaccine development. It will include a review of epidemiological data generated in the field, which will address spatio-temporal diversity of DENV epidemics, the importance of cross-reactive protection and of the time-interval between infections as a predictor of disease. It will further include a review of the role of both the innate and adaptive immunity in DENV infection control, and discuss the usefulness of new improved animal models in dissecting the role of each immunological compartment, which will help define new correlate of immune protection. New data concerning the DENV structure and anti-dengue antibody structure will address the necessity of improved neutralization assays. The ultimate test to prove vaccine efficacy and study immune correlates of protection in humans before large trials will open up the discussion on human DENV challenges using controlled attenuated viral strains. Finally, the role of vaccines, administered in flavi-immune populations, in the modification of future epidemics will also be approached and will include novel studies on mosquitoes infection thresholds.

Download or read book Dengue and Zika Control and Antiviral Treatment Strategies written by Rolf Hilgenfeld and published by Springer. This book was released on 2018-05-29 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: This contributed volume contains 25 chapters from leading international scientists working on dengue and Zika viruses, who came together in Praia do Tofo in Mozambique to discuss the latest developments in the fields of epidemiology, pathogenesis, structural virology, immunology, antiviral drug discovery and development, vaccine efficacy, and mosquito control programs. The meeting venue offered an opportunity to discuss current research on these flaviviruses in an idyllic setting, and also to develop first-hand appreciation of the issues in infectious diseases facing developing countries and of the research gaps in Africa. For readers, who should include basic and clinical researchers in the field and public health professionals, the chapters are organized to provide a comprehensive overview of the various topics in current dengue and Zika virus research. A unique feature of the proceedings of this meeting is the inclusion of the discussions that took place following presentations. These have been transcribed and appended to the end of the relevant chapters, and they form the “salt in the soup” of this book.

Book excerpt: Stimulation with live dengue virus of peripheral blood mononuclear cells from a dengue 4-immune donor generated virus-specific serotype cross-reactive CD4- CD8+ class I-restricted cytotoxic T lymphocytes (CTL) capable of lysing dengue virus-infected autologous fibroblasts and cells pulsed with dengue antigens of all 4 serotypes. These CTL lysed autologous fibroblasts infected with vaccinia-dengue recombinant viruses containing the E, or several non-structural dengue 4 genes. These results demonstrate that both dengue structural and non-structural proteins are targets for the HLA class I-restricted, CD4- CD8+ CTL. (JES).

Download or read book Chimpanzees in Biomedical and Behavioral Research written by National Research Council and published by National Academies Press. This book was released on 2011-12-05 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many years, experiments using chimpanzees have been instrumental in advancing scientific knowledge and have led to new medicines to prevent life-threatening and debilitating diseases. However, recent advances in alternate research tools have rendered chimpanzees largely unnecessary as research subjects. The Institute of Medicine, in collaboration with the National Research Council, conducted an in-depth analysis of the scientific necessity for chimpanzees in NIH-funded biomedical and behavioral research. The committee concludes that while the chimpanzee has been a valuable animal model in the past, most current biomedical research use of chimpanzees is not necessary, though noted that it is impossible to predict whether research on emerging or new diseases may necessitate chimpanzees in the future.

Available in PDF, EPUB and Kindle. Book excerpt: In this first book dedicated entirely to the ELISPOT, a critical enzyme-linked immunospot assay used widely in biomedical research, recognized experts with first-hand experience detail how to design, perform, and analyze these assays. The readily reproducible techniques they provide cover a wide variety of topics, including the use of membrane-backed plates, the standardization and validation procedures, the removal of cells from ELISPOT plates, cell separation techniques, and the quantification of ELISPOT data. There are also numerous ELISPOT applications involving animal models, human cells, measles, multiple sclerosis, immune responses, multicytokine detection systems, and immunocytochemistry. Highlights include dual-color and multiplex ELISPOT assays, use of the ELISPOT assay on feline lymphocytes, standardization of the ELISPOT procedure, and combining the ELISPOT assay with immunohistochemistry.

Download or read book Japanese Encephalitis and West Nile Viruses written by John Mackenzie and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: Japanese encephalitis and West Nile viruses are members of the Japanese encephalitis serological group of the genus Flavivirus and therefore closely related genetically and antigenically. They share a number of properties, including the use of birds as their major wildlife maintenance host and Culicine mosquitoes for transmission, and they are both associated with severe human disease, as well as fatal infections in horses. The emergence of these two viruses, and their well-established propensity to colonise new areas, make it timely to re-examine their ecology, biology, molecular structure, replication and epidemiology, and these therefore provide the focus of this volume.
