immune response in human leishmania infections

Abstract

This review summarizes relevant information about the immune response triggered during leishmaniosis, a disease of great importance from the epidemiological point of view, since it is endemic in Colombia and other countries. We emphasize on human leishmaniosis; nevertheless, some important findings in the murine model are also mentioned. This information allows to conclude that Leishmania infection is a complex and coordinated process, which includes adhesion and entrance of the parasite into the host cells and its survival inside them. Events that mediate the infection process may influence its result in terms of elimination of the parasite or development of the disease, through induction or not of an effective specific immune response which involves host cell activation and parasite destruction.
