Cruzipain Promotes Trypanosoma cruzi Adhesion to Rhodnius prolixus Midgut
BACKGROUND Trypanosoma cruzi is the etiological agent of Chagas' disease. Cysteine peptidases are relevant to several aspects of the T. cruzi life cycle and are implicated in parasite-mammalian host relationships. However, little is known about the factors that contribute to the parasite-insect host interaction. METHODOLOGY/PRINCIPAL FINDINGS Here, we have investigated whether cruzipain could...
متن کاملMetalloproteases in Trypanosoma rangeli-infected Rhodnius prolixus.
Protease activities in the haemolymph and fat body in a bloodsucking insect, Rhodnius prolixus, infected with Trypanosoma rangeli, were investigated. After SDS-polyacrylamide gel electrophoresis containing gelatin as substrate, analysis of zymograms performed on samples of different tissues of controls and insects inoculated or orally infected with short or long epimastigotes of T. rangeli, dem...
متن کاملEffects of Infection by Trypanosoma cruzi and Trypanosoma rangeli on the Reproductive Performance of the Vector Rhodnius prolixus
The insect Rhodnius prolixus is responsible for the transmission of Trypanosoma cruzi, which is the etiological agent of Chagas disease in areas of Central and South America. Besides this, it can be infected by other trypanosomes such as Trypanosoma rangeli. The effects of these parasites on vectors are poorly understood and are often controversial so here we focussed on possible negative effec...
متن کاملExploring the role of insect host factors in the dynamics of Trypanosoma cruzi-Rhodnius prolixus interactions.
Members of the subfamily Triatominae, family Reduviidae, comprise a large number of insect species of which some are vectors of Trypanosoma cruzi, the causative agent of Chagas' disease. This article outlines research on the process of transformation and the dynamics of developmental stages of Trypanosoma cruzi in the triatomine insect hosts. Special attention is given to the interactions of pa...
متن کاملBiological factors involving Trypanosoma cruzi life cycle in the invertebrate vector, Rhodnius prolixus.
Trypanosoma cruzi, the ethiologic agent of Chagas disease (Chagas 1909), is transmitted through triatomine vectors during the meal on the invertebrate host. The parasite displays quite distinct morphological and functional forms, alternating between replicative stages (epimastigotes in the vector midgut and amastigotes in vertebrate cells) and infective, non-dividing forms (metacyclic trypomast...
