Project description:Comparative genomic analysis of T. cruzi CLB vs Trypanosoma rangeli (strains SC, Choachí, C23, H14, R1625 and PIT10) and Trypanosoma conorhini
Project description:This laboratory is focusing on to clarify the biologic relevance of a virulence factor known as trans-sialidase from Trypanosoma cruzi, the agent of the Chagas disease (American trypanosomiasis).

Project description:Antibody recognition of Trypanosoma cruzi conserved proteins was assessed by evaluating pools of patient IgG samples on microarrays of 400,000 peptides covering these proteins as 15-mers with an overlap of 13 amino acids.
Project description:Evaluation of differential gene expression during the metacyclogenesis process in Trypanosoma cruzi, comparing three stages (epimastigotes, stressed epimastigotes and 24h adhered epimastigotes in differentiation) and using both total and polysomal mRNA.
Project description:The intracellular pathogen Trypanosoma cruzi secretes an activity that blocks TGF-β-dependent induction of connective tissue growth factor (CTGF/CCN2). Here, we address the mechanistic basis for T. cruzi-mediated interference of CTGF/CCN2 expression by examining host cell signaling pathways and the global inhibitory effect on TGF-β-dependent gene expression. We show that the expression of a discrete subset of TGF-β-inducible genes involved in cell proliferation, wound repair, and immune regulation are blocked by the soluble T. cruzi activity, demonstrating that this parasite-derived activity has broad, but specific effects on fibroblast gene regulation.
