Expresión diferencial de proteínas en el estómago de Meccus Pallidipennis bajo la infección por Trymanosoma Cruzi

Abstract

The triatomines (Triatominae, Reduviidae) are strict hematophagous transmitters of the parasite Trypanosoma cruzi, etiological agent of Chagas disease. These parasites constituting a public health problem in Latin America. Its digestive system is divided into three regions: anterior, middle and posterior. Posterior region is where the biological cycle of T. cruzi is completed. Information on molecular mechanisms associated with interaction of T. cruzi within stomach of the insect vector is scarce, with a passive role of food storage attributed to this organ. However, it should not be overlooked that here occurs the differentiation of sanguineous trypomastigote to epimastigote. In addition, parasites face to existing components in this fraction such as digestive enzymes, defensins and agglutinins
