Administration of artinm lectin reduces the severity of the acute phase infection with Trypanosoma cruzi

FASEB BioAdvances, Volume 3, Issue 5, Page 295-304, May 2021., 2021
Abstract The acute phase of experimental Trypanosoma cruzi infection is associated with a strong inflammatory reaction, physiological changes, amastigote nests in tissues, and hematological alterations. ArtinM, a lectin extracted from Artocarpus heterophyllus seeds, is a homotetramer exhibiting immunomodulatory properties that promotes Th1 immune ...

Protein Profiles of Trypanosoma cruzi and Trypanosoma rangeli [PDF]

Parasitología latinoamericana, 2004
Trypanosoma cruzi, is a protozoan parasite, which has a close phylogenetic relationship with Trypanosoma rangeli that is not pathogenic for the vertebrate host. Both parasites have antigenic similarity, they have different and complex total protein profiles according to their morphological and physiological stage epimastigotes or trypomastigotes ...

Trypanosoma rangeli and Trypanosoma cruzi: cross-reaction among their immunogenic components [PDF]

Memórias do Instituto Oswaldo Cruz, 1996
It has been demonstrated that immuno-modu-lating mechanisms induced by epimastigotes ofTrypanosoma rangeli, an assumed harmless hu-man parasite, may have relevance to protectionagainst Trypanosoma cruzi, the causative organ-ism of Chagas’ disease (B Basso et al. 1991 Am JTrop Med Hyg 44: 413-419).

Extent of polymorphism and selection pressure on the Trypanosoma cruzi vaccine candidate antigen Tc24

Evolutionary Applications, Volume 13, Issue 10, Page 2663-2672, December 2020., 2020
Abstract Introduction Chagas disease, caused by the protozoan parasite Trypanosoma cruzi, is a major public health problem in the Americas, and existing drugs have severe limitations. In this context, a vaccine would be an attractive alternative for disease control.

The zinc finger proteins ZC3H20 and ZC3H21 stabilise mRNAs encoding membrane proteins and mitochondrial proteins in insect‐form Trypanosoma brucei

Molecular Microbiology, Volume 113, Issue 2, Page 430-451, February 2020., 2020
African trypanosomes are parasites that can grow in the blood of mammals, as "bloodstream forms", and the digestive system of Tsetse flies as "procyclic forms". ZC3H20 and ZC3H21 are related trypanosome proteins that can bind to mRNA. They are absent in growing bloodstream forms, but present in procyclic forms.

A Trypanosoma cruzi Genome Tandem Repetitive Satellite DNA Sequence as a Molecular Marker for a LAMP Assay for Diagnosing Chagas’ Disease

Disease Markers, Volume 2020, Issue 1, 2020., 2020
Chagas’ disease is a neglected tropical disease caused by Trypanosoma cruzi which is endemic throughout Latin America and is spread by worldwide migration. Diagnosis is currently limited to serological and molecular techniques having variations regarding their sensitivity and specificity.

Expression of Fluorescent Genes in Trypanosoma cruzi and Trypanosoma rangeli (Kinetoplastida: Trypanosomatidae): Its Application to Parasite-Vector Biology [PDF]

, 2005
Two Trypanosoma cruzi-derived cloning vectors, pTREX-n and pBs:CalB1/CUB01, were used to drive the expression of green fluorescent protein (GFP) and DsRed in Trypanosoma rangeli Tejera, 1920, and Trypanosoma cruzi Chagas, 1909, isolates, respectively ...
