Download or read book Current Topics in Malaria written by Alfonso J. Rodriguez-Morales and published by Intechopen. This book was released on 2016-11-30 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: Malaria causes hundreds of thousands of human deaths every year, and the World Health Assembly has made it a priority. To help eliminate this disease, there is a pressing need for the development and implementation of new strategies to improve the prevention and treatment, due in part to antimalarial drug resistances. This chapter focuses on two strategies to inactivate the malaria parasite in blood, which are photodynamic therapy (PDT) and inhibition of hemozoin formation. The PDT strategy permits either a control of the proliferation of mosquito larvae to develop some photolarvicides for the prevention or a photoinactivation of the malaria parasite in red blood cells (RBCs) to minimize infection transmission by transfusion. The inhibition of hemozoin formation strategy is used for the development of new antimalarial drug by understanding its formation mechanism.

Research is ultimately gaining more grounds in the quest to provide vaccine for the prevention of malaria. The book features research aimed to bring a lasting solution to the malaria problem and what we should be doing now to face malaria, which is definitely useful for health policies in the twenty first century.

Download or read book Molecular Parasitology written by Julia Walochnik and published by Springer. This book was released on 2016-10-20 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past years, genome projects for numerous human parasites have been completed and now allow first in depth comparisons and evolutionary conclusions. The genomes of parasites reflect the coevolution with their host, metabolic capacities depending on their respective habitat in the host. Gut parasites usually have an anaerobic metabolism, while blood parasites have an aerobic metabolism, intracellular parasites escape the immune system, while extracellular parasites evade the immune system, usually by antigenic variation. Comprehensive genome data now being available allow us to address profound scientific questions, such as which traits enable the parasite to survive in the human host, which to cause disease and which can be used as drug targets. This book intends to give an overview of the state of knowledge on “the molecules” of protozoan parasites – on their genomes, proteomes, glycomes and lipidomes.

Download or read book Breaking the cycle attacking the malaria parasite in the liver written by Ute Frevert and published by Frontiers Media SA. This book was released on 2016-01-06 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite significant progress in the global fight against malaria, this parasitic infection is still responsible for nearly 300 million clinical cases and more than half a million deaths each year, predominantly in African children less than 5 years of age. The infection starts when mosquitoes transmit small numbers of parasites into the skin. From here, the parasites travel with the bloodstream to the liver where they undergo an initial round of replication and maturation to the next developmental stage that infects red blood cells. A vaccine capable of blocking the clinically silent liver phase of the Plasmodium life cycle would prevent the subsequent symptomatic phase of this tropical disease, including its frequently fatal manifestations such as severe anemia, acute lung injury, and cerebral malaria. Parasitologists, immunologists, and vaccinologists have come to appreciate the complexity of the adaptive immune response against the liver stages of this deadly parasite. Lymphocytes play a central role in the elimination of Plasmodium infected hepatocytes, both in humans and animal models, but our understanding of the exact cellular interactions and molecular effector mechanisms that lead to parasite killing within the complex hepatic microenvironment of an immune host is still rudimentary. Nevertheless, recent collaborative efforts have led to promising vaccine approaches based on liver stages that have conferred sterile immunity in humans – the University of Oxford's Ad prime / MVA boost vaccine, the Naval Medical Research Center’s DNA prime / Ad boost vaccine, Sanaria Inc.'s radiation-attenuated whole sporozoite vaccine, and Radboud University Medical Centre’s and Sanaria's derived chemoprophylaxis with sporozoites vaccines. The aim of this Research Topic is to bring together researchers with expertise in malariology, immunology, hepatology, antigen discovery and vaccine development to provide a better understanding of the basic biology of Plasmodium in the liver and the host’s innate and adaptive immune responses. Understanding the conditions required to generate complete protection in a vaccinated individual will bring us closer to our ultimate goal, namely to develop a safe, scalable, and affordable malaria vaccine capable of inducing sustained high-level protective immunity in the large proportion of the world’s population constantly at risk of malaria.

Download or read book Infectious Diseases written by Phyllis Kanki and published by Springer Science & Business Media. This book was released on 2012-12-15 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: Infectious Diseases: Selected Entries from the Encyclopedia of Sustainability Science and Technology presents authoritative, peer-reviewed contributions from leading experts on a wide range of major infectious diseases of global importance. Infectious diseases account for more than 17 million deaths each year worldwide. While modern medicine and technology have diminished the threat of many of these pathogens in high-income countries, the ever present threats of re-emerging infections, population mobility, natural disasters, and pathogen genetic variability are but some of the reasons for the dynamic threat of this broad category of risks to human health. An indispensable resource for students and scientists, the volume also covers some of the new technologies currently under development for infectious disease prevention, treatment, and eradication. The greater part of the infectious disease burden remains in the tropics, where low and middle-income countries lack the resources, infrastructure, and health systems to mount or sustain control efforts. Many contributions describe the efforts of the scientific research community and international donor agencies to achieve the integrated goals of vigilant surveillance, improved and cost-effective diagnostics, and treatment for sustainable disease control.

Book excerpt: Currently, malaria kills more than 300,000 people per year, making it a top priority of world leaders and international organizations, who are working towards implementing and coordinating efforts to eradicate this disease. An effective malaria vaccine is recognized as the key element that will decide between success and failure in this fight. At present, despite intensive research efforts, such a vaccine is not yet available for use. However, there are a number of advanced candidate vaccines with high chances of success in the short term. Malaria: Immune Response to Infection and Vaccination provides a comprehensive view on the immune response to malaria and to the different vaccines under development. The book offers the following: - Contributions by top research leaders in the field, - Comparisons of the immune responses to both malaria infection and malaria vaccines, which are traditionally treated separately, - Coverage of the immune responses to the different stages of malaria, which are frequently treated as separate fields of research.

Download or read book Epitope Discovery and Synthetic Vaccine Design written by Clarisa Beatriz Palatnik-de-Sousa and published by Frontiers Media SA. This book was released on 2018-07-12 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since variolation, conventional approaches to vaccine development are based on live-attenuated, inactivated or purified pathogen-derived components. However, effective vaccines against global health threats such as HIV, parasite infections and tumors are difficult to achieve. On the other hand, synthetic vaccines based on immunogenic epitopes offer advantages over traditional vaccines since they are chemically defined antigens free from deleterious effects. Additionally, in contrast to live-attenuated vaccines, they do not revert to virulence in immunocompromised subjects, and different from genetic vaccines, they do not involve ethical questions. Traditional vaccines contain PAMPs and induce strong immune responses, while recombinant vaccines are less potent. In spite of the immunogenic weakness previously attributed to epitope-based vaccines a synthetic vaccine containing a 17 amino acid-epitope of the Pseudomonas aeruginosa Type IV pilus exceeded the protective potential of its cognate protein composed of 115 amino acids. Therefore, the efficacy yield of a synthetic vaccine can be potentiated by using the proper combination of target epitopes. Recent advances in adjuvant development, immunogen platforms for DNA vaccines and viral vectors also contributed to optimize immunogenicity. Another constraint to the use of epitope vaccines was their restriction to some MHC or HLA phenotypes. However, epitopes containing 20 or less amino acids of Plasmodium falciparum and Leishmania donovani bind to multiple HLA-DR and MHC receptors. Thus synthetic epitope vaccines may better meet the requirements of the regulatory agencies since they have lower costs and are easier to produce. The classical experimental approach for the development of an epitope-based vaccine involves the use of recombinant domains or overlapping 15-mer peptides spanning the full length of the target antigen, and the analysis of the induced antibody and/or T cell immune responses in vitro or in vivo. On the other hand, in silico tools can select peptides that are more likely to contain epitopes, reducing the number of sequence candidates. T cell epitope prediction dates back to 1980s, when the first algorithm was developed based on the identification of amphipathic helical regions on protein antigens. Since then, new methods based on MHC peptide-binding motifs or MHC-binding properties have been developed. The recent reverse vaccinology concept uses high-throughput genome sequencing and bioinformatics tools to identify potential targets of immune responses. The feasibility of this approach was shown for the first time in the design of a vaccine against Neisseria meningitides that is now in phase III clinical trials. In addition, different computational tools allow the determination of crucial gene(s) through comparative analyses between different pathogenic strains Alternatively, carbohydrates have been considered as key targets in developing safe and effective vaccines to combat cancer, bacterial and viral infections. Tumor associated carbohydrate antigens can be coupled covalently to protein carriers to target MHC receptors and improve immunogenicity and have reached already pre-clinical and clinical studies. In light of the recent availability of genomic tools, we believe that in the near future an increasing number of vaccine candidates, composed of defined epitopes, will be available for synthetic vaccines showing improved protection.

Download or read book Malaria written by Dyann Fergus Wirth and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Malaria is a mosquito-borne disease caused by parasitic protozoa that belong to the genus Plasmodium. This disease imposes a significant global health burden, claiming the lives of several thousand children and pregnant women each day. Increasing antimalarial drug resistance and the complexity of the Plasmodium life cycle, among other factors, have made eradication difficult. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Medicine examines the biology, pathology, and epidemiology of malaria, as well as ongoing efforts to treat infections and manage their spread. Contributors discuss the Plasmodium life cycle, focusing on the molecular mechanisms by which the various parasitic stages induce clinical symptoms, interact with the immune system, and lead to further transmission of malaria. They also explore topics such as the interaction between mosquito reproduction and Plasmodium development, epigenetic regulation of malaria-associated genes, and unique features of malaria in pregnant women (e.g., parity-dependent susceptibility) and describe how an improved understanding of these phenomena may lead to novel intervention strategies. The driving forces behind antimalarial drug resistance are covered, as is progress in developing an effective vaccine and controlling mosquito populations. This volume is therefore an essential reference for all scientists, clinicians, and public health professionals interested in understanding malaria and reducing its devastating effects.

Download or read book Molecular Evolution of the Major Histocompatibility Complex written by Jan Klein and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: From molecules to populations and back In biology, the most vigorous organisms often ensue from a union of two disparate, pure lines. In science, too, laws of hybrid vigor seem to operate at the interface between two disciplines, an interface that often proves to be fertile ground for germinating concepts and new outlooks. The fringes of research into the major histocompatibility complex (Mhc) have provided such an interface several times in the past and the encounters have invigorated fields such as transplantation biology, cellular immunology, and immunogenetics. In the last few years, a new interface has been emerging between Mhc and evolutionary genetics, and particularly the branch of evolutionary genetics dealing with molecular evolution. Mhc research relies upon molecular evolutionary genetics, with its grand superstructure of mathematical formulations, to come to grips with the events leading to and maintaining the Mhc polymorphism. Without the armament of rigorous statistical procedures developed by evolutionary geneticists, the intricate relationships among Mhc genes cannot be resolved. It will undoubtedly be a molecular geneticist who is the final arbiter in the dispute concerning the nature of the selection pressure molding the Mhc genes. And it is doubtful whether the true function of Mhc can ever be comprehended without the vantage point afforded by the elucidation of its evolutionary history.
