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

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.

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 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

Available in PDF, EPUB and Kindle. Book excerpt: Emerging and re-emerging pathogens pose several challenges to diagnosis, treatment, and public health surveillance, primarily because pathogen identification is a difficult and time-consuming process due to the “novel” nature of the agent. Proper identification requires a wide array of techniques, but the significance of these diagnostics is anticipated to increase with advances in newer molecular and nanobiotechnological interventions and health information technology. Human Emerging and Re-emerging Infections covers the epidemiology, pathogenesis, diagnostics, clinical features, and public health risks posed by new viral and microbial infections. The book includes detailed coverage on the molecular mechanisms of pathogenesis, development of various diagnostic tools, diagnostic assays and their limitations, key research priorities, and new technologies in infection diagnostics. Volume 1 addresses viral and parasitic infections, while volume 2 delves into bacterial and mycotic infections. Human Emerging and Re-emerging Infections is an invaluable resource for researchers in parasitologists, microbiology, Immunology, neurology and virology, as well as clinicians and students interested in understanding the current knowledge and future directions of infectious diseases.

Download or read book Darwin s Illness written by Ralph Colp and published by . This book was released on 2008 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: The year 2009 will mark the bicentennial of Charles Darwin's birth and the 150th anniversary of the publication of The Origin of Species. From 1840 to his death in 1882, Darwin was constantly plagued by chronic illnesses that allowed him to work only a few hours at a time and by an obsession with his physical health. Was this the psychosomatic product of stress resulting from the development and public reception to his theory of evolution or the result of a disease or parasite obtained during the world traveler's excursions? In 1977 Ralph Colp Jr. argued persuasively for the former explanation in his book To Be an Invalid: The Illness of Charles Darwin, now out of print, but considered to be one of the century's most important works on Darwin's life. Expanding and reworking his earlier arguments to take into account new information (including Darwin's "Diary of Health," included as an appendix), Darwin's Illness paints a more intimate portrait of the nature and possible causes of Darwin's lifelong illness, of the ways he and Victorian physicians tried treating it, and how it influenced his scientific work and relations with his family and friends.
