Differential transcriptome of human dendritic cells at first contact with Trypanosoma cruzi reveals response to virus as a central unexplored pathway

ABSTRACT: Chagas disease is a notorious public health problem worldwide. However, the pathology is still poorly understood in humans and dendritic cells (DCs) have a determinant role during infection that could help to understand what happens with immune response during the first contact. Here we performed a transcriptomic analysis of the interaction between DCs from three human donors and the infective forms of T. cruzi for 12 h. 468 differentially expressed genes (DEGs) were found in DCs after infection. KEGG and GO enrichment analysis showed that most of DEGs are involved in pathways related to virus infection and intracellular receptors, as NOD and RIG-I -like receptors. Some of these DEGs were validated through RT-qPCR, corroborating the transcriptome data. Cytokine measurement partially corresponded to the transcript levels. In conclusion, this study has revealed the virus response as an unexplored pathway in Chagas disease, which brings new perspectives for this pathology.

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 hearts of wild-type C57BL/6 mice infected with T. cruzi and controls (uninfected)

Project description:An efficient innate immune recognition of the intracellular parasite T. cruzi is crucial for host protection against development of Chagas disease, which often leads to multiple organ damage, particularly the heart leading to cardiomyopathy. Mechanisms modulated by MyD88 have been shown to be necessary for resistance against T, cruzi infection. Recently, Nod-like receptors have been shown to play an important role as innate immune sensors, particularly as they relate to inflammasome function, caspase activation, and inflammatory cytokine production. In this study, we aimed to investigate the participation of innate immune responses in general, and inflammasomes in particular, in heart inflammation and cardiac damage upon infection with the T. cruzi parasite. We used microarrays to gain insight into gene expression in the cardiac tissue of mice infected with the causative agent of Trypanosoma cruzi, and identified distinct classes of up-regulated genes during this process, including important genes involved in inflammasome activation and innate immune responses in general.

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

Notch receptor expression in Trypanosoma cruzi infected Human Umbilical Vein Endothelial Cells treated with benznidazole or aspirin as revealed by microarray analysis

Project description:Chagas disease is a parasitic infection originally endemic to latinamerican countries but now spreaded worldwide that can be transmitted congenitally. Current specific therapy involves benznidazole, however, other therapies may modify gene expression that can change genetic expression profile, allowing cell programming to provide a more unfavorable environment for intracellular parasite development. Herein, microarray analysis was performed to Human Umbilical Vein Endothelial Cells (HUVEC), treated with benznidazole and the anti-inflammatory drugs aspirin or simvastatin, and infected with T. cruzi, the causative agent of Chagas disease.

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.

Widespread, focal copy number variations (CNV) in Trypanosoma cruzi strains

Project description:Trypanosoma cruzi is a protozoan parasite and the etiologic agent of Chagas disease, an important public health problem in Latin America. T. cruzi is diploid, almost exclusively asexual, and displays an extraordinarily diverse population structure both genetically and phenotypically. Yet, to date the genotypic diversity of T. cruzi and its relationship, if any, to biological diversity have not been studied at the whole genome level. In this study, we used whole genome oligonucleotide tiling arrays to compare gene content in biologically disparate T. cruzi strains by comparative genomic hybridization (CGH). We observed that T. cruzi strains display widespread and focal copy number variations (CNV) and a substantially greater level of diversity than can be adequately defined by the current genetic typing methods. As expected, CNV were particularly frequent in gene family-rich regions containing mucins and trans-sialidases but were also evident in core genes. Gene groups that showed little variation in copy numbers among the strains tested included those encoding protein kinases and ribosomal proteins, suggesting these loci were less permissive to CNV. Moreover, frequent variation in chromosome copy numbers were observed, and chromosome-specific CNV signatures were shared by genetically divergent T. cruzi strains, suggesting a greater degree of chromosome exchange than previously thought.
