Download or read book An Exported Malaria Protein Regulates Glucose Uptake During Intraerythrocytic Infection written by Tamira K. Butler and published by . This book was released on 2014 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Malaria is the world's second biggest infectious killer after tuberculosis. It accounts for 219 million cases each year, with an estimated 660,000 deaths. The majority of these deaths occur in sub-Saharan Africa, in children under 5 years old. In addition to Africa, malaria is endemic to Asia, Central and South America, the Caribbean and the Middle East. Plasmodium falciparum (P. falciparum) is the protozoan parasite that is responsible for the deadliest form of human malaria. Plasmodia are carried by the female Anopheles mosquito and infected into humans during a blood meal. The parasites invade liver cells and form merozoites which erupt from liver cells to invade red blood cells. The intraerythrocytic cycle of infection is responsible for the clinical manifestations of malaria, namely fever and chills. The intraerythrocytic cycle is also the stage of disease that is most studied and targeted for treatment. Although treatment for malaria is available, drug-resistant forms of the parasite are increasingly rampant. For this reason, new, more effective treatments for malaria are necessary. To develop these treatments, we must have a better understanding of the biological processes that the parasite employs to survive in the host to cause disease. In 1996, an international effort was launched to sequence the genome of P. falciparum with the expectation that the genome sequence could be exploited in the search for new drugs and vaccines to fight malaria. In 2002, the genome sequence was published with gaps in some chromosomes. Approximately 5,300 protein-encoding genes were identified; of these about 60% were labeled as hypothetical proteins. Our studies focus on determining the function of one hypothetical protein, PFB0923c, that we now call Glucose Uptake Restoration Protein (GURP). We show that GURP localizes to novel double membrane vesicles in the RBC cytosol and is essential during P. falciparum intraerythrocytic infection. GURP interacts with and sequesters the host protein stomatin, which is known to depress glucose uptake in mammalian cells. Knockdown of GURP decreases glucose uptake and impairs parasite growth in RBCs. This phenotype can be rescued with antioxidants, suggesting that hexose monophosphate/pentose phosphate pathway impairment is lethal in the knockdown parasites. GURP C183 is essential to parasite viability and trafficking of GURP vesicles to the RBC cytosol. Together, these data demonstrate that GURP is essential to P. falciparum viability and glucose uptake during infection of red blood cells.

Download or read book Parasites and Parasitic Diseases written by Gilberto Antonio Bastidas Pacheco and published by BoD – Books on Demand. This book was released on 2019-04-24 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parasitic diseases are considered nowadays as an important public health problem due to the high morbidity and mortality rates registered in the world. These diseases result in more severe consequences for the social order of tropical and subtropical countries because many of them have low economic income that makes it even more difficult to design and implement health control programs. This situation opens the door to the emergence and reemergence of these diseases; therefore, it is convenient, necessary, and essential to study and update the epidemiological behavior of tropical diseases with the objective of offering official health professionals and institutions current information for decision-making in this area to ensure social welfare.

This book was released on 2008-04-30 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is an urgent need to uncover new therapies that will protect against malaria, as the parasite becomes increasingly resistant to available drugs and this book offers insights into three interrelated aspects of the malaria-infected erythrocyte: * The transport of solutes into and out of the infected cell and the use of specific trafficking pathways in drug targeting * The traffic of proteins produced by the intracellular parasite as an essential process for the biogenesis of transport systems. * The relationship between the transport of drugs into the infected cell and the mode of drug action and drug resistance.
Download or read book The Blood brain Barrier written by William M. Pardridge and published by Lippincott Williams & Wilkins. This book was released on 1993 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: The characterization of the blood-brain barrier (BBB) is undergoing a paradigm shift as the century-old concept of a passive, impermeable barrier that segregates blood and brain interstitial fluid is giving way to the idea that the BBB is a dynamic conduit for the transport between blood and brain of those nutrients, peptides, proteins, or immune cells that have access to certain transport systems localized within the BBB membranes. This volume contains 20 contributed chapters organized in four parts: cell-cell interactions, subcellular organelle function, signal transduction mechanisms, and gene expression. There is also a foreword by the late W.H. Oldendorf (1925-1992) on the teleology of the blood-brain barrier and the survival advantage conferred upon the organism by its presence in the vertebrate brain.

Download or read book Antimalarial Natural Products written by A. Douglas Kinghorn and published by Springer Nature. This book was released on 2022-01-02 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume begins with a short history of malaria and follows with a summary of its biology. It then traces the fascinating history of the discovery of quinine for malaria treatment, and then describes quinine’s biosynthesis, its mechanism of action, and its clinical use, concluding with a discussion of synthetic antimalarial agents based on quinine’s structure. It also covers the discovery of artemisinin and its development as the source of the most effective current antimalarial drug, including summaries of its synthesis and biosynthesis, its mechanism of action, and its clinical use and resistance. A short discussion of other clinically used antimalarial natural products leads to a detailed treatment of additional natural products with significant antiplasmodial activity, classified by compound type. Although the search for new antimalarial natural products from Nature’s combinatorial library is challenging, it is very likely to yield new antimalarial drugs. This book thus ends by identifying ten natural products with development potential as clinical antimalarial agents.

Download or read book Proteases in Human Diseases written by Sajal Chakraborti and published by Springer. This book was released on 2017-07-13 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book bridges the gap between fundamental research and biomedical and pharmacological applications on proteases. It represents a comprehensive overview of the multifaceted field of proteases in cellular environment and highlights the recently elucidated functions of complex proteolytic systems in different diseases. Several established investigators have elucidated the crucial role of proteases in biological processes, including how proteolytic function and regulation can be combined to develop new strategies of therapeutic interventions. Proteases form one of the largest and most diverse families of enzymes known. It is now clear that proteases are involved in every aspect of life functions of an organism. Under physiological conditions, proteases are regulated by their endogenous inhibitors; however, when the activity of proteases is not regulated appropriately, disease processes can result in. So, there is absolute need for a stringent control of proteolytic activities in cells and tissues. Dysregulation of proteases may cause derangement of cellular signalling network resulting in different pathophysiological conditions such as vascular remodelling, atherosclerotic plaque progression, ulcer and rheumatoid arthritis, Alzheimer disease, cancer metastasis, tumor progression and inflammation. Additionally, many infective microorganisms require proteases for replication or use proteases as virulence factors, which have facilitated the development of protease-targeted therapies for a variety of parasitic diseases.
