CCL Signaling Drives T Cell–Macrophage Crosstalk in the Mouse Colon During Chronic Trypanosoma cruzi Infection

ABSTRACT: Chagas disease, caused by the protozoan Trypanosoma cruzi, is a chronic infection characterized by low levels of parasite persistence in tissues such as the heart, gastrointestinal tract, and skeletal muscle. The mechanisms underlying digestive Chagas disease (DCD), particularly within the colon, remain incompletely defined. To characterize the immune landscape during chronic infection, we used a murine model of DCD and performed single-cell RNA sequencing of colonic lamina propria cells. Immune profiling revealed infiltration of T cells, B cells, and macrophages, with T cells representing the predominant immune population in the chronically infected colon. Computational cell–cell communication analysis predicted activation of chemokine signaling pathways, including the CCL5–CCR5 axis, mediating interactions between CD8+ T cells and macrophages. Processed single-cell gene expression matrices and associated metadata are provided in this submission

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

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

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.

Trypanosoma cruzi interaction with host tissues modulate the composition of large extracellular vesicles

Project description:Trypanosoma cruzi is the protozoan that causes Chagas disease, an endemic parasitosis in Latin America that has spread around the globe. Recently, a series of studies indicate that the gastrointestinal tract represents an important reservoir for T. cruzi in the chronic phase. It is also known that, during contact between T. cruzi and host cells, there is a release of extracellular vesicles (EVs) that modulates the immune system and enhances the infection, but the dynamics of secretion of host and parasite molecules through these EVs is not understood. In this study, we used two cell lines to simulate the environments found by the parasite in the host: C2C12 cell (myoblast) and Caco-2 cell (intestinal epithelium). We isolated large EVs (LEVs) from the interaction of T. cruzi culture-derived trypomastigotes (TCTs) belonging to two distinct strains (CL Brener, DTU Tc VI and Dm28c DTU Tc I) in contact with C2C12 and Caco-2 cells to 2 hours and after 24 hours of infection. The interaction of the parasite with the host cell induces a switch in the functionality of proteins carried by LEVs and a varied tissue answer. Protein-protein interaction analysis indicates that LEVs carry key proteins for host-pathogen interaction that could participate in the pathogenesis 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.

Transcriptome analysis of mouse hearts infected with Trypanosoma cruzi: Differential modulation of gene expression by two strains

Project description:Purpose: One important challenge in the field of Chagas disease research is to determine the main factors leading to the establishment of the parasite in some organs in the chronic stage, mainly the heart and/or digestive system. Our group previously showed that distinct strains of T. cruzi (JG and Col1.7G2) presented differential tissue distribution in the chronic stage in double-infected BALB/c mice. To investigate changes in the host triggered by the two distinct T. cruzi strains, we assessed the gene expression profile of BALB/c mouse hearts infected with either JG, Col1.7G2 or an equivalent mixture of both parasites during the initial phase of infection. Results: We demonstrate a clear distinction in host gene expression modulation by both parasites. Col1.7G2 strongly activated Th1-polarized immune response genes, whereas JG showed minor immune response activation. Moreover, JG strongly impaired the expression of genes for ribosomal proteins and mitochondrial proteins related to the electron transport chain and the citric acid cycle. Interestingly, evaluation of gene expression in mice inoculated with the mixture of parasites showed expression profiles for both up- and downregulated genes, indicating the coexistence of both parasite strains in the heart during the acute phase. Conclusions: We suggest that different strains of T. cruzi may be distinguished by their efficiency in activating the immune system, modulating host energy and reactive oxygen species production and impairing protein synthesis during early infection, which may be decisive in defining parasite persistence in specific organs.

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.
