Evolution on the immunopathology of Chagas disease.

Immunosuppressive drugs as a tool to explore immunopathology in experimental Chagas disease.

Chagas Disease Cardiomyopathy: Immunopathology and Genetics

Chagas disease, caused by the protozoan Trypanosoma cruzi, is endemic in Latin America and affects ca. 10 million people worldwide. About 30% of Chagas disease patients develop chronic Chagas disease cardiomyopathy (CCC), a particularly lethal inflammatory cardiomyopathy that occurs decades after the initial infection, while most patients remain asymptomatic. Mortality rate is higher than that ...

In vitro Anti-epimastigote Activity of some Iranian Medicinal Plants

Some medicinal plants are a potential source of new drugs, in order to improve the treatment of Chagas disease whose treatment is still a challenge. In this study, the in vitro anti-epimastigote activity of certain fractions of Achillea biebersteinii, A. millefolium, Satureja mutica and S. macrantha was evaluated. Diethyl ether fractions of Achillea species and acetone fractions of Satureja spe...

Chagas disease and HIV co-infection: genetic analyses of two Trypanosoma cruzi strains under experimental immunosuppression

BACKGROUND: Recently new aspects of the immunopathology of Chagas disease have been described in patients infected with HIV and unusual clinical manifestations such as cutaneous lesions, involvement of central nervous system and/or serious cardiac lesions related to the reactivation of the parasite have been reported. Two uncloned Trypanosoma cruzi strains previously isolated from chronic chaga...

The implications of immunopathology for parasite evolution.

By definition, parasites harm their hosts, but in many infections much of the pathology is driven by the host immune response rather than through direct damage inflicted by parasites. While these immunopathological effects are often well studied and understood mechanistically in individual disease interactions, there remains relatively little understanding of their broader impact on the evoluti...
