BACKGROUND Human cutaneous leishmaniasis is caused by distinct species, including Leishmania amazonensis. Treatment of cutaneous leishmaniasis is far from satisfactory due to increases in drug resistance and relapses, and toxicity of compounds to the host. As a consequence for this situation, the development of new leishmanicidal drugs and the search of new(More)
The present study demonstrates that the endosymbiont of Crithidia deanei influences the expression of surface gp63 molecules. Ultrastructural immunocytochemical analysis shows the presence of the gp63-like protein in the protozoan flagellum and flagellar pocket, either attached to shed membranes or in a free form. This molecule is(More)
Crithidia deanei is an insect trypanosomatid that harbors a bacterial endosymbiont in its cytoplasm. In this work, we have demonstrated the influence of the endosymbiont on the interaction of C. deanei with mammalian fibroblasts, also implicating the surface leishmanolysin-like molecules of C. deanei in this process. The wild strain of C. deanei expressed a(More)
