Proteome of Panstrongylus megistus digestive tract

ABSTRACT: Panstrongylus megistus are insect triatomines and vectors of the protozoan Trypanosoma cruzi responsible for human Chagas' disease. Considering that T. cruzi multiplies inside the triatomine digestive tract (TDT), the analysis of the TDT protein profile is an essential step to understand TDT physiology during T. cruzi infection. To characterize the protein profile of TDT of P. megistus, a shotgun liquid chromatography-tandem mass spectrometry (LC-MS/MS) approach was applied in this report.

Transcriptome analysis by microarray of human placental chorionic villi explants infected with Trypanosoma cruzi

Project description:Chagas’ disease, one of the major public health concerns in Latin America, is caused by the haemophlagelated protozoan Trypanosoma cruzi (T. cruzi). In the past few years congenital transmission of T. cruzi has become more important, and partly responsible for the “globalization of Chagas’ disease”. The congenital transmission, although with low rates, represents the main route of transmission in non-endemic countries and endemic countries without vectorial transmission, and represents one third of the new cases each year. Diverse pathogens, including T. cruzi, are able to cross the placental barrier and infect both the placenta and fetus. However, the exact cellular and molecular mechanisms of host-pathogen interaction between T. cruzi and the placenta has been scarcely studied. The use of microarray analysis to determine expression profiles constitutes a powerful tool in order to identify genes and pathways related to the host response to infections. Here, we analyzed the transcriptomic response of human placental chorionic villi explants (HPCVE) challenged with T. cruzi trypomastigotes at low (105) and high (106) concentrations for 2 and 24 hours

Transcriptome profile of Trypanosoma cruzi-infected cells

Project description:As Trypanosoma cruzi, the etiological agent of Chagas disease, multiplies in the cytoplasm of nucleated host cells, infection with this parasite is highly likely to affect host cells. We performed an exhaustive transcriptome analysis of T. cruzi-infected HeLa cells using an oligonucleotide microarray containing probes for greater than 47,000 human gene transcripts. In comparison with uninfected cells, those infected with T. cruzi showed greater than threefold up-regulation of 41 genes and greater than threefold down-regulation of 23 genes. Real-time reverse transcriptase-polymerase chain reaction (RT-PCR) of selected, differentially expressed genes confirmed the microarray data. Many of these up- and down-regulated genes were related to cellular proliferation, including seven up-regulated genes encoding proliferation inhibitors and three down-regulated genes encoding proliferation promoters, strongly suggesting that T. cruzi infection inhibits host cell proliferation, which may allow more time for T. cruzi to replicate and produce its intracellular nests. These findings provide new insight into the molecular mechanisms by which intracellular T. cruzi infection influences the host cell, leading to pathogenicity. Keywords: infection response

Expression data from human primary fibroblasts, endothelial and smooth muscle cells infected with Trypanosoma cruzi

Project description:Trypanosoma cruzi is an obligate intracellular protozoan parasite that causes human Chagas’ disease, a leading cause of heart failure in Latin America. Using Affymetrix oligonucleotide arrays we screened phenotypically diverse human cells (foreskin fibroblasts, microvascular endothelial cells and vascular smooth muscle cells) for a common transcriptional response signature to T. cruzi. A common feature was a prominent type I interferon response, indicative of a secondary response to secreted cytokines. Using transwell plates to distinguish cytokine-dependent and -independent gene expression profiles in T. cruzi-infected cells, a core cytokine-independent response was identified in fibroblasts and endothelial cells that featured metabolic and signaling pathways involved in cell proliferation, amino acid catabolism and response to wounding. Significant downregulation of genes involved in mitotic cell cycle and cell division predicted that T. cruzi infection impedes cell cycle progression in the host cell.
