This book was released on 2003-08-31 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chagas' disease, which results from infection with the single cell parasite Trypanosoma cruzi, is a debilitating condition that is a major problem in many parts of Latin America. Rapid technical progress is now facilitating dissection of the molecular mechanisms of disease pathogenesis, a process that will ultimately provide new strategies to alleviate the enormous public health burden associated with the infection. In this book, international experts review the buoyant status of Chagas' disease research as we enter the "post-genome" era and speculate on how the new findings will impact on drug and vaccine development. The chapters outline how progress is being made on several fronts ranging from parasite population genetics to human immunology. Researchers, physicians and students with an interest in any aspect of molecular parasitology should find this book to be a valuable reference

Book Synopsis Molecular Mechanism of Chagas' Disease: Lymphocyte Activation by the Trypanosoma cruzi trans-Sialidase by : Wenda Gao
Download or read book Molecular Mechanism of Chagas' Disease: Lymphocyte Activation by the Trypanosoma cruzi trans-Sialidase written by Wenda Gao and published by Universal-Publishers. This book was released on 2002-02-17 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polyclonal lymphocyte activation and hypergammaglobulinemia characterize the acute phase of Chagas' disease, a debilitating condition caused by Trypanosoma cruzi. Such pathogenic hyper-reactivities not only compromise specific host defense against the pathogen, but may also contribute to infection-induced chronic autoimmune responses. Characterizing parasite-derived factors driving non-specific immune responses will provide insights for parasite evasion of host specific immunity. This study shows that T. cruzi trans-sialidase (TS) is one such polyclonal activator for normal murine lymphoid and non-lymphoid cells in at least three aspects. First, TS induces aggregation of immune cells and secretion of cytokines, such as IL-6. Second, TS is a T-independent B cell mitogen, directly stimulating polyclonal B cell proliferation independent of IL-6, CD40, CD43, Toll-like receptor-4 (TLR-4), and mIg crosslinking. While TS is mitogenic to wild-type B cells, mostly CD5- B2 cells, it fails to induce any proliferation of B cells from Bruton's tyrosine kinase (Btk)-defective X-linked immune deficient (xid) mice, suggesting that Btk is involved in TS signaling. Furthermore, in vivo administration of TS is followed by polyclonal Ig secretion that peaks 4-6 days after injection, before detectable TS-specific antibodies. Third, although TS does not directly stimulate T cells, it potentiates antigen specific and nonspecific T cell responses through the activation of APC, such as macrophages and B cells. TS potentiation is observed in splenocytes deficient of CD28, ICAM-1, CD40L or CD43. However, optimal TS-potentiation requires IL-6 and Btk, as it is significantly reduced in splenocytes from IL-6 -/- and xid mice. The C-terminal tandem repeat domain (LTR), but not the N-terminal catalytic domain (CD) of TS, is the active moiety that mediates TS-induced cell aggregation, IL-6 secretion, B cell and macrophage activation. At non-mitogenic concentrations, however, LTR inhibits mouse T cell activation and blocks TS-potentiated T cell response. A working model for the actions of TS, its domains and TS receptor is proposed. The results indicate that TS is a parasite-derived factor that directly and indirectly activates both APC and T cells, disturbing host lymphocyte homeostasis and cytokine regulation. Thus, TS may drive polyclonal lymphocyte activation in acute infection, potentially contributing to the immune evasion of the parasite, as well as the autoimmune abnormality in chronic Chagas' disease.
Book Synopsis Chagas Disease by : Jaime Marcelo Altcheh
Download or read book Chagas Disease written by Jaime Marcelo Altcheh and published by Springer Nature. This book was released on 2019-09-09 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chagas disease is a potentially life threatening condition that was historically mainly endemic to Latin America. Over the last decade, however, the disease has spread to and is increasingly prevalent in other continents such as North America and Europe, with an estimated 7 million people infected worldwide. It is primarily transmitted by insect vectors that carry the parasite Trypanosoma cruzi, the disease agent. In areas where there is vector control and in non-endemic countries, it is mainly transmitted via congenital infection. Cardiac and gastrointestinal complications are common in untreated individuals. This book offers a comprehensive overview of Chagas disease, including its vectorial and congenital transmission, and molecular diagnosis, which is essential for screening, and developing and providing timely, effective anti-trypanosomal treatment. Written by experts working with infected patients on a daily basis, it discusses the pathogenesis of congenital, cardiac, gastrointestinal and oral Chagas disease, as well as its treatment and the pharmacological aspects of drug development in this area. Chapter "Chagas Disease Treatment Efficacy Biomarkers: Myths and Realities" is available open access under a via link.springer.com.

Book Synopsis American Trypanosomiasis by : Kevin M. Tyler
Download or read book American Trypanosomiasis written by Kevin M. Tyler and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: American trypanosomiasis, or Chagas disease, is caused by the protozoan parasite, Trypanosoma cruzi. Sixteen to eighteen million people are currently infected with this organism, and 45,000 deaths are attributed to the disease each year. Infection with T. cruzi is life-long, and 10-30% of persons who harbor the parasite chronically develop cardiac and gastrointestinal problems associated with the parasitosis. Although major progress has been made in recent years in reducing vector-borne and transfusion-associated transmission of T. cruzi, the burden of disability and death in persons chronically infected with the organism continues to be enormous. Eight to ten million persons born in countries in which Chagas disease is endemic currently reside in the United States, and epidemiologic and census data suggest that 50,000-100,000 are chronically infected with T. cruzi. The presence of these infected persons poses a risk of transmission of the parasite in the USA through blood transfusion and organ transplantation and several such cases have now been documented. American Trypanosomiasis, volume seven of World Class Parasites is written for students of tropical medicine, parasitology and public health, for researchers and practitioners alike who wish to bring themselves abreast of the status quo with respect to this disease. It is intended to supplement formal textbooks, in order to broaden and illuminate current areas of scientific and public health concern. Uniquely for T. cruzi, this book addresses parasite, vector and host biology, the pathogenesis of Chagas disease and current and prospective therapeutics and control strategies in a single volume.
Book Synopsis American Trypanosomiasis by : Jenny Telleria
Download or read book American Trypanosomiasis written by Jenny Telleria and published by Elsevier. This book was released on 2010-09-03 with total page 871 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chagas disease causes severe socioeconomic impact and a high medical cost in Latin America. WHO and the World Bank consider Chagas disease as the fourth most transmittable disease to have a major impact on public health in Latin America: 120 million persons are potentially exposed, 16 to 18 million of whom are presently infected, causing 45,000 to 50,000 deaths per year. It has been calculated that approximately 2.4 million potential working years are lost because of incapacity and mortality due to the disease, for an annual cost estimated at 20 billion Euros. American Trypanosomiasis provides a comprehensive overview of Chagas disease and discusses the latest discoveries concerning the three elements that compose the transmission chain of the disease: - The host: human and mammalian reservoirs - The insect vectors: domestic and sylvatic vectors - The causative parasite: Trypanosoma cruzi - Informs and updates on all the latest developments in the field - Contributions from leading authorities and industry experts

Book Synopsis The Biology of Trypanosomes by : Leslie Hudson
Download or read book The Biology of Trypanosomes written by Leslie Hudson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: African and South American trypanosomiases are notable features of clinical and veterinary practice in their respective endemic areas and, as such, are of considerable economic importance. Scientifically, however, their importance ex tends beyond their clinical significance, as the trypano somes are intriguing and easily manipulated models for the study of the control of gene expression, membrane chemistry, proliferation and differentiation. It is clear from the scientific press that the rate of advance has "hotted" up in these areas of trypanosome research over the past 5 years and so a single-topic volume within the scope of the present series seemed timely. As ever, the final admix ture of review topics was a compromise between what was appropriate and what was available - fortunately with the former in vast excess. I should like to highlight two omissions, made for en tirely different reasons. The first is a detailed treatment of the molecular biology of the variant surface glycopro teins of the African trypanosomes (in particular Trypano soma brucei and T. equiperdum). This topic has been the subject of several reviews, for example, BORST and CROSS (1982)1 and TURNER (1982)2, and so was excluded from the present volume. The second omission is a review of the first-class work on genetic recombination from the group of Dr. Leo Jenni at the Schweizerisches Tropeninsti tut, Basel. This group has used isoenzyme markers to show that T.
