Characterization of the pattern of ribosomal protein L19 production during the lifecycle of Leishmania spp.

Leishmania is a genus of protozoan parasites causing a wide clinical spectrum of diseases in humans. Analysis of a region of chromosome 6 from Leishmania major (Iribar et al.) showed that the transcript of a putative L19 ribosomal protein (RPL19) was most abundant at the amastigote stage.

Unveiling benznidazole's mechanism of action through overexpression of DNA repair proteins in Trypanosoma cruzi.

Benznidazole (BZ) is the most commonly used drug for the treatment of Chagas disease. Although BZ is known to induce the formation of free radicals and electrophilic metabolites within the parasite Trypanosoma cruzi, its precise mechanisms of action are still elusive. Here, we analyzed the survival of T.

Characterization of anti-silencing factor 1 in Leishmania major.

Anti-silencing factor 1 (ASF1) is a histone chaperone that contributes to the histone deposition during nucleosome assembly in newly replicated DNA. It is involved in chromatin disassembly, transcription activation and in the cellular response to DNA damage. In Leishmania major the ASF1 gene (LmASF1) is located in chromosome 20 and codes for a protein showing 67% of identity with the Trypanosoma brucei TbASF1a.
