Vaccination with epimastigotes of different strains of Trypanosoma rangeli protects mice against Trypanosoma cruzi infection

Memorias do Instituto Oswaldo Cruz, 2008
In our laboratory, we have developed a model of vaccination in mice with Trypanosoma rangeli, a non-pathogenic parasite that shares many antigens with Trypanosoma cruzi. The vaccinated mice were protected against infection with virulent T. cruzi.

Production, purification and crystallization of a trans-sialidase from Trypanosoma vivax [PDF]

, 2015
Sialidases and trans-sialidases play important roles in the life cycles of various microorganisms. These enzymes can serve nutritional purposes, act as virulence factors or mediate cellular interactions (cell evasion and invasion).

Characterization and immobilization of engineered sialidases from Trypanosoma rangeli for transsialylation [PDF]

, 2017
A sialidase (EC 3.2.1.18; GH 33) from non-pathogenic Trypanosoma rangeli has been engineered with the aim of improving its transsialylation activity.

Experimental Vaccines against Chagas Disease: A Journey through History

Journal of Immunology Research, Volume 2015, Issue 1, 2015., 2015
Chagas disease, or American trypanosomiasis, which is caused by the protozoan parasite Trypanosoma cruzi, is primarily a vector disease endemic in 21 Latin American countries, including Mexico. Although many vector control programs have been implemented, T. cruzi has not been eradicated. The development of an anti‐T.

Trypanosoma rangeli protein tyrosine phosphatase is associated with the parasite's flagellum

Memorias do Instituto Oswaldo Cruz, 2012
Protein tyrosine phosphatases (PTPs) play an essential role in the regulation of cell differentiation in pathogenic trypanosomatids. In this study, we describe a PTP expressed by the non-pathogenic protozoan Trypanosoma rangeli (TrPTP2).

Trypanosoma cruzi Infection and Host Lipid Metabolism

Mediators of Inflammation, Volume 2014, Issue 1, 2014., 2014
Trypanosoma cruzi is the causative agent of Chagas disease. Approximately 8 million people are thought to be affected worldwide. Several players in host lipid metabolism have been implicated in T. cruzi‐host interactions in recent research, including macrophages, adipocytes, low density lipoprotein (LDL), low density lipoprotein receptor (LDLR), and ...

Detection of Trypanosoma cruzi and Trypanosoma rangeli infection in triatomine vectors by amplification of the histone H2A/SIRE and the sno-RNA-C11 genes Detecção da infecção por Trypanosoma cruzi e Trypanosoma rangeli em vetores triatomíneos através da amplificação dos gens de histona H2A/SIRE e sno-RNA-C11

Revista do Instituto de Medicina Tropical de São Paulo, 2007
Trypanosoma rangeli is non pathogenic for humans but of important medical and epidemiological interest because it shares vertebrate hosts, insect vectors, reservoirs and geographic areas with T. cruzi, the etiological agent of Chagas disease.

Partial Purification of Integral Membrane Antigenic Proteins from Trypanosoma evansi That Display Immunological Cross‐Reactivity with Trypanosoma vivax

Journal of Parasitology Research, Volume 2014, Issue 1, 2014., 2014
Trypanosoma evansi and Trypanosoma vivax, which are the major causative agents of animal trypanosomosis in Venezuela, have shown a very high immunological cross‐reactivity. Since the production of T. vivax antigens is a limiting factor as this parasite is difficult to propagate in experimental animal models, our goal has been to identify and isolate ...
