DNA Methylation in macrophages infected with spp. in different culture conditions.

modulate the host cell epigenome, including DNA methylation. This work aimed to explore the DNA methylation pattern in infected macrophages with , and . We performed a genome-wide methylation analysis in macrophages, cultured in presence/absence of interleukin 6 (IL-6) and infected with the three species for a period of 72hs.

Development of a Fluorescent Assay to Search New Drugs Using Stable tdTomato-, and the Selection of Galangin as a Candidate With Anti-Leishmanial Activity.

Antimonials continue to be considered the first-line treatment for leishmaniases, but its use entails a wide range of side effects and serious reactions. The search of new drugs requires the development of methods more sensitive and faster than the conventional ones. We developed and validated a fluorescence assay based in the expression of tdTomato protein by , and we applied this method to evaluate the activity of flavonoids and reference drugs.

High performance of an enzyme linked immunosorbent assay for American tegumentary leishmaniasis diagnosis with Leishmania (Viannia) braziliensis amastigotes membrane crude antigens.

The diagnosis of American tegumentary leishmaniasis (ATL) still requires the design of more effective tools. Leishmania (Viannia) braziliensis is the causal agent of the 90% of Argentinean ATL cases. Considering the current knowledge, an ELISA based crude antigen (CA) for the diagnosis was designed.

Efficacy of Topical Treatment with (-)-Epigallocatechin Gallate, A Green Tea Catechin, in Mice with Cutaneous Leishmaniasis.

The treatment of leishmaniasis includes pentavalent antimony drugs but, because of the side effects, toxicity and cases of treatment failure or resistance, the search of new antileishmanial compounds are necessary. The aims of this study were to evaluate and compare the in vitro antileishmanial activity of four green tea catechins, and to assess the efficacy of topical (-)-epigallocatechin gallate in a cutaneous leishmaniasis model. The antileishmanial activity of green tea catechins was evaluated against intracellular amastigotes, and cytotoxicity was performed with human monocytic cell line.
