Description

Introduction:

Trypanosoma cruzi, the parasite that causes Chagas disease, requires of essential metabolites and cofactors to guarantee its survival. This parasite must supply its quota of metal ions such as copper (Cu), iron (Fe), calcium (Ca), etc. T. cruzi depends on a mitochondrial respiratory chain with the contribution of a cytochrome c oxidase type aa3 (COX) enzyme as the main oxidase. The COX enzyme, in addition to the 2 heme A molecules (an and a3), also requires Cu ions for its activity. Mitochondrial function and COX activity are essential for parasite proliferation and infectivity.

METHODOLOGICAL INFORMATION

Complete methodological information is available in the Readme.docx file and in the descriptive metadata of each file.

Value of the data:

This data is the first work that provides information on the copper metabolism in T. cruzi. Copper is an essential cofactor for aerobic organisms and at the same time is a toxic element in high quantities. For these reasons, there must be transport for this ion and at the same time it must be a controlled transport. In this work we analyzed the tolerance to Cu stress, in excess and deficiency, and in the different stages of the life cycle. The transcriptional response of a selection of genes that, we propose, are involved in the control of Cu ion homeostasis was studied.

La enzima COX, además de las 2 moléculas de hemo A (a y a3), también requiere de iones Cu para su actividad. La función mitocondrial y la actividad de COX es esencial para la proliferación e infectividad del parásito.

Relevancia de los datos:

Este trabajo es el primer trabajo que aporta datos acerca del metabolismo de cobre T. cruzi. El cobre es un cofactor esencial para los organismos aeróbicos y al mismo tiempo es un elemento tóxico en altas cantidades. Es por esto que debe existir un transporte para este ión y al mismo tiempo debe ser un transporte controlado. En este trabajo se analizó la tolerancia al estrés por Cu, en exceso y defecto, en los distintos estadios del ciclo de vida. Se estudió la respuesta transcripcional de una selección de genes que, proponemos, están involucrados en el control de la homeostasis de iones Cu.
