Trypanosoma cruzi infection induces a global host cell response in cardiomyocytes.
Chagas' disease, caused by the hemoflagellate protozoan Trypanosoma cruzi, affects millions of people in South and Central America. Chronic chagasic cardiomyopathy, the most devastating manifestation of this disease, occurs in approximately one-third of infected individuals. Events associated with the parasite's tropism for and invasion of cardiomyocytes have been the focus of intense investiga...
متن کاملEarly Trypanosoma cruzi Infection Reprograms Human Epithelial Cells
Trypanosoma cruzi, the causative agent of Chagas disease, has the peculiarity, when compared with other intracellular parasites, that it is able to invade almost any type of cell. This property makes Chagas a complex parasitic disease in terms of prophylaxis and therapeutics. The identification of key host cellular factors that play a role in the T. cruzi invasion is important for the understan...
متن کاملTrypanosoma cruzi Infection and Endothelin-1 Cooperatively Activate Pathogenic Inflammatory Pathways in Cardiomyocytes
Trypanosoma cruzi, the causative agent of Chagas' disease, induces multiple responses in the heart, a critical organ of infection and pathology in the host. Among diverse factors, eicosanoids and the vasoactive peptide endothelin-1 (ET-1) have been implicated in the pathogenesis of chronic chagasic cardiomyopathy. In the present study, we found that T. cruzi infection in mice induces myocardial...
متن کاملImmediate/early response to Trypanosoma cruzi infection involves minimal modulation of host cell transcription.
Host cell infection by the intracellular pathogen, Trypanosoma cruzi, involves activation of signaling pathways, cytoskeletal reorganization, and targeted recruitment of host cell lysosomes. To determine the consequences of T. cruzi invasion on host cell gene expression, high density microarrays consisting of approximately 27,000 human cDNAs were hybridized with fluorescent probes generated fro...
متن کاملTrypanosoma cruzi infection and nuclear factor kappa B activation prevent apoptosis in cardiac cells.
Studies of cardiac pathology and heart failure have implicated cardiomyocyte apoptosis as a critical determinant of disease. Recent evidence indicates that the intracellular protozoan parasite Trypanosoma cruzi, which causes heart disease in chronically infected individuals, impinges on host apoptotic pathways in a cell type-dependent manner. T. cruzi infection of isolated neuronal cells and ca...
