This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Malarial blood stage antigens can produce humoral immunity by induction of protective antibodies to epitopes on surface antigens on parasites. The merozoite surface protein-1 (MSP1) of P. falciparum is a major blood-stage vaccine candidate. MSP1 may play a role in binding and/or infection of erythrocytes by merozoites (parasites) during red blood cell invasion. The C-terminal fragment of MSP1, MSP1(sub 19), is highly conserved among all known strains of P. falciparum. immunization with recombinant proteins that have native-like conformations may elicit long-lasting protective immunity that mimics the natural immunity. We have used bacterial expression to tightly regulate transcription and translation of MSP1(sub 42). Plasmids that encode MSP1(sub 42) were prepared and tested for their ability to express recombinant protein. A three column purification scheme that included Ni(+2) metal chelate chromatography, anion and then cation exchange chromatography, yielded greater than 95% pure MSP1(sub 42). Immunoreactivity with mAbs showed that recombinant MSP1(sub 42) was conformationally similar to native MSP1. The objectives were to develop recombinant MSP1(sub 42) molecules that were structurally correct, to develop fermentation and purification processes that could be scaled-up for large-scale processes, and ultimately, to advance these products into human clinical trials.

Download or read book Production of a Recombinant E Coli Expressed Malarial Vaccine from the C Terminal Fragment of Plasmodium Falciparum 3D7 Merozoite Surface Protein 1 written by and published by . This book was released on 2000 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: P. falciparum Merozoite Surface Protein-1 (MSP-1) is a leading erythrocytic stage vaccine candidate. Following secondary proteolytic processing, it may play a role in binding and/or invasion of erythrocytes. The secondary processing gives a 33kD and 19kD fragment. The MSP1-19 is a target for parasite inhibitory antibodies and protective immunity. However, it appears to lack T-helper epitopes. Since antibody is likely the effector mechanism induced by MSP1-19, it is important to insure that recombinant vaccines based on this antigen be folded correctly and contain T-helper epitopes that will enhance induction of humoral responses. We have developed recombinant MSP1-42 molecules that are structurally correct based on positive reactivities with conformation-dependent mAbs. These proteins have been produced to greater than 95% purity and exceed FDA endotoxin standards. Immunogenicity studies in mice and Rhesus monkeys reveal that good antibody responses are induced to MSP1-42 when these animals are immunized with the MSP1-42 plus SBAS2 adjuvant.
Download or read book Molecular Immunological Considerations in Malaria Vaccine Development written by Michael F. Good and published by CRC Press. This book was released on 1993-10-13 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some of the world's leading research scientists in the field have contributed to this new book on malaria vaccine development. The book examines various strategies being pursued against the different stages of the parasite (the sporozoite, asexual erythrocytic stages, and sexual stages). It describes vaccines that combat the parasite directly, vaccines aimed at preventing disease, vaccines based on attenuated parasites, and vaccines based on small, carefully defined synthetic peptides. The book provides a compendium of current approaches, lists of preferred antigens, and the results of vaccine trials to date. Molecular immunology involved with both the natural immune response to parasites and with the constraints on inducing immunity are emphasized throughout the book. Views on how vaccines may be tested and then integrated into malaria control programs are also discussed. Molecular Immunological Considerations in Malaria Vaccine Development will be useful for researchers and students in immunology, parasitology, biotechnology, vaccine design, and tropical and public health.

Download or read book Malaria Vaccines The Continuing Quest written by Irwin W Sherman and published by World Scientific. This book was released on 2016-03-29 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2013, 200 million people were infected with malaria, resulting in over 584,000 deaths, with the potential to affect over half the world's population. Such is the widespread nature of malaria that it is increasingly believed only a vaccine will lead to its eradication.Although the first attempt at a vaccine was made a century ago, it is only in the last 30 years that real progress in testing has been made, in the hope of discovering a molecule that can provide long-lasting protection against the disease. In July 2015, GlaxoSmithKline (GSK) announced that after 30 years of research it had received the green light from the European Medicines Agency for the world's first malaria vaccine, RTS, S, for use in African children aged 6 weeks to 17 months.This book chronicles the development of RTS, S — done in collaboration with the Walter Reed Army Institute for Research, the PATH Malaria Vaccine Initiative (MVI) and funded in part by the Bill and Melinda Gates Foundation — as well as previous candidate vaccines. It also focusses on the continuing quest to find more effective vaccines against this continuing health crisis. Finally, it provides an easily understood background on recombinant DNA and monoclonal antibodies and places them in perspective to their contributions to malaria vaccine development.This book serves as a convenient and easily accessible source of information for students, teachers, microbiologists, parasitologists, physicians, clinicians and research funders.
Download or read book Immunity to Malaria and Vaccine Strategies written by Kevin N. Couper and published by Frontiers Media SA. This book was released on 2019-10-10 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: Malaria, caused by infection with protozoan parasites belonging to the genus Plasmodium, is a highly prevalent and lethal infectious disease, responsible for 435,000 deaths in 2017. Optimism that malaria was gradually being controlled and eliminated has been tempered by recent evidence that malaria control measures are beginning to stall and that Plasmodium parasites are developing resistance to front-line anti-malarial drugs. An important milestone has been the recent development of a malaria vaccine (Mosquirix) for use in humans, the very first against a parasitic infection. Unfortunately, this vaccine has modest and short-lived efficacy, with vaccinated individuals possibly being at increased risk of severe malarial disease when protection wanes. Thus, to define new ways to combat malaria, there remains an urgent requirement to identify the immune mechanisms that promote resistance to malarial disease and to understand why these so often fail. The review and primary research articles in this Research Topic illustrate the breadth of research performed worldwide aimed to understand the biology of the Plasmodium parasite, the roles of the various cell types that act within the immune response against the parasite, and the parasitological and immunological basis of severe malarial disease. The articles in section 1 exemplify the different vaccination strategies being developed and tested by the research community in the fight against malaria. The articles in section 2 review important overarching aspects of malaria immunology and the use of models to study human malaria. The articles in section 3 describe the ways through which the Plasmodium parasite is initially recognised by the immune system during infection, how the parasite can directly impact this critical event to restrict anti-Plasmodial immunity, and resolve the roles of key innate cell populations, such as dendritic cells, in coordinating malarial immunity. The articles in sections 4-6 outline the roles T and B cell populations play during malaria, highlighting the activation, diversification and regulation of the crucial cell types during malaria, and discuss some of the reasons adaptive immunity to malaria is often considered so poor compared with other diseases. The articles in section 7 provide up to date information on the pathogenesis of cerebral malaria, bridging our understanding of the syndrome in humans with information learned from animal models. Overall, the articles in this research, many of which are published by leaders in the malaria field, emphasize the imagination and technical advances being employed by researchers against malaria. We acknowledge the initiation and support of this Research Topic by the International Union of Immunological Societies (IUIS). We hereby state publicly that the IUIS has had no editorial input in articles included in this Research Topic, thus ensuring that all aspects of this Research Topic are evaluated objectively, unbiased by any specific policy or opinion of the IUIS.

This book was released on 2019 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Development of a highly efficacious vaccine will be necessary for malaria elimination. Studies in Plasmodium falciparum endemic areas indicate that naturally acquired antibody responses to MSP2 are associated with resistance to malaria, making PfMSP2 an attractive vaccine candidate. To overcome challenges encountered with subunit malaria vaccines, we established that the use of highly immunogenic rPfMSP8 as a carrier protein for vaccine candidates rPfMSP119 and rPfs25 facilitated production, minimized antigenic competition and enhanced induction of functional antibodies. Here, we exploited the benefits of our rPfMSP8 fusion partner to optimize a rPfMSP2-based subunit vaccine. A synthetic PfMSP2 (3D7) codon harmonized gene was used to produce unfused rPfMSP2 or chimeric rPfMSP2/8 in E. coli. Purified, rPfMSP2 formed amyloid-like fibrils in vitro, however rPfMSP2/8 did not. Immunization of rabbits and mice with both rPfMSP2 antigens elicited high titer anti-PfMSP2 antibodies that recognized the major allelic variants of native PfMSP2. Competition assays revealed differences in antibody specificities induced by the two rPfMSP2-based vaccines, with evidence of epitope masking by rPfMSP2-associated fibrils. Immunogenicity studies in mice demonstrated that formulation of rPfMSP2 vaccines with GLA-SE, a synthetic TLR4 agonist, elicited cytophilic IgG isotypes and production of Th1-associated cytokines. T cell responses were specific for epitopes within PfMSP2 and PfMSP8 domains. The rPfMSP2/8 + GLA-SE formulation induced significantly higher antibody titers with superior durability and capacity to opsonize P. falciparum merozoites for phagocytosis. Immunization with a trivalent vaccine including PfMSP2/8, PfMSP1/8 and Pfs25/8 induced high levels of antigen-specific antibody, with no evidence of antigenic competition. These results are highly encouraging for the addition of rPfMSP2/8 as a component of an efficacious, multivalent, multistage malaria vaccine.

Download or read book Rodent Malaria written by R. Killick-Kendrick and published by Elsevier. This book was released on 2012-12-02 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rodent Malaria reviews significant findings concerning malaria parasites of rodents, including their taxonomy, zoogeography, and evolution, along with life cycles and morphology; genetics and biochemistry; and concomitant infections. This volume is organized into eight chapters and begins by sketching out the history of the discovery of rodent as well as aspects of parasitology, immunology, and chemotherapy. These concepts are investigated two decades following Ignace Vincke's major discovery and Meir Yoeli's successful establishment of the method of cyclical transmission of the parasite. The following chapters focus on the taxonomy and systematics of the subgenus Vinckeia, with reference to the concepts of species and subspecies of animals and the degree to which they apply to malaria parasites, in particular to those of rodents. The discussion then shifts to how the rodent malaria parasites provide a unique insight into the subcellular organization of Plasmodium species, the use of rodent malaria as an experimental model to study immunological responses, and infectious agents that interact with malaria parasites. The book concludes with a chapter on malaria chemotherapy, with emphasis on the value of rodent malaria in antimalarial drug screening and the use of antimalarial drugs as biological probes. This book will be of interest to protozoologists and physicians as well as those from other disciplines including biochemistry, immunology, pharmacology, cell biology, and genetics.
