Abstract

Human leishmaniasis, both the cutaneous or muco-cutaneous forms, as well as the systemic visceral form, remain representing till how, an important public health problem around the world, especially in tropical and subtropical areas of the globe, where geographic, climate and social-economic factors contribute for the maintenance and dispersion of these diseases. In this way, Latin America appears as one of most compromised areas by these injuries, where some countries such as Brazil, in the South America, and Panama and Honduras, in the Central America, present an interesting epidemiological feature due to some peculiarities related not only to the antigenic capacity of Leishmania species, as well as the interaction of these parasites with the human Immune response, resulting in the immunopatogenetic process that can give rise to the tegumentary leishmaniasis or systemic visceral leishmaniasis. The imunopathogenetic basis are one of the targets of greatest interest of this project, which will be Investigated by gene expression and in situ phenotypic markers, trying to better understanding the cell signaling factors and the cytokines profiles of innate and adaptive immune responses of the hosts related to these different forms of the disease.
