In mammalian cells, the Rab7 protein is a key element of late endocytic membrane traffic. Several results suggest that it is involved in the transport from early to late endosome or from late endosome to lysosome. We have previously characterized a Rab7 gene homologue (TcRAB7) in Trypanosoma cruzi. Now, using an affinity-purified antibody specific to TcRAB7 protein we have determined that it is localized at the Golgi apparatus of the parasite. Our results indicate that the T. cruzi Rab7 homologue may function in a different route than its counterparts in mammalian cells.

Artemisinin-based treatments (ACTs) are the first therapy currently used to treat malaria produced by . However, in recent years, increasing evidence shows that some strains of are less susceptible to ACT in the Southeast Asian region. A data reanalysis of several omics approaches currently available about parasites of that have some degree of resistance to ACT was carried out.

The Polymerase Chain Reaction (PCR) test is a highly sensitive, specific, and rapid diagnostic tool for Chagas disease. Chagas disease is caused by the protozoan flagellate and is endemic to the Americas. While conventional serological methods are still used in the diagnosis of Chagas disease, they are being gradually replaced by molecular methods like PCR.

Cruzipain (CZP) is an essential cysteine protease of , the etiological agent of Chagas disease, and a promising druggable target. To date, no CZP inhibitors have reached clinical use, with research efforts mostly hampered by insufficient potency, limited target selectivity or lack of bioactivity translation from the isolated enzyme to the parasite in cellular environments. In this study, we report the design of , a 1,2,3-triazole-based targeted covalent inhibitor with nanomolar potency (IC = 28 nM) and null inhibition of human cathepsin L.

Background: Endemic in more than 20 countries, Chagas disease affects 6.3 million people worldwide, leading to 28,000 new infections and 7700 deaths each year. Previous meta-analyses on antiparasitic treatment need updates to encompass recent studies and to assess key clinically meaningful endpoints.
