Immunobiology of experimental cutaneous leishmaniasis.
The study of the murine model of infection with Leishmania major is providing important insights into the understanding of the complex interactions between the host and intracellular pathogens. Using this model system, basic research is actively leading to the identification of host factors promoting or circumventing the development of immunity to L. major. Here, Geneviève Milon, Giuseppe Del Giudice and Jacques A. Louis review recent results related to the characterization of immunological host factors determining resistance and susceptibility to this parasite, and try to identify areas where further research is required for a better understanding of the complex events triggered by intracellular parasites within their hosts. Extrapolation to the human leishmaniases of the rapid advances made in this murine model of infection, should pave the way to the rational design of future immunoprophylactic and immunotherapeutic measures.
