Abstract

Leishmaniasis is a tropical diseases present in more than 98 countries, being the second most common parasitosis after malaria, which results in 20,000-30,000 deaths annually. It is caused by the flagellate protozoan of the genus Leishmania, which comprises more than 20 species that lead to different manifestations of Leishmaniasis, as visceral leishmaniasis, cutaneous, mucocutaneous and cutaneous-diffuse.Often asymptomatic, the Leishmaniasis are difficult to diagnose, being the immunological and molecular methods the most used. Proteomics, which uses mass spectrometry as main methodology, has aided the immunological and molecular methods to better understand the biological role during the illness and the virulence-pathogenicity and pathogen-host interactions.This project aims to compare the proteome and their post-translational modifications (phosphorylation and glycosylation) of three species of Leishmania: L. (V.) braziliensis, L. (L.) amazonensis and L. (L.) chagasi. This analysis will be essential to generate a proteomic map that will provide: 1) database for the scientific community, 2) the re-annotation of genome of these species with proteogenomic metholodogy and 3) the possibility of better comprehend the intracellular signaling and its relationship with the form and manifestations of the disease.
