| Abstract: | Trypanosoma evansi is a worldwide distributed hemoparasite with a strong economic impact in veterinary activities. Despite widespread knowledge about the etiology of the disease caused by T. evansi, there are few detailed studies about the metabolism of this parasite. The aim of this study was to determine the presence of Acetylcholinesterase (AChE) in T. evansi through a strategy of subcellular localization and confocal microscopy. The localization of the AChE by differential and isopycnic centrifugation strategy showed that this enzyme has a predominant localization in the glycosome, similar to hexokinase, and it is not present in either the cytosol or the plasma membrane. This study shows novel data that help to understand the non-neuronal role of AChE in the Trypanosomatidae family. |
