Leishmaniasis in Brazil: clinical and immunopathogenetic aspects of the human and experimental disease

Abstract

The ACL presents a large spectrum of manifestation, varying from asymptomatic and/or sub clinical in resistant individuals till different forms in susceptible individuals, such as localized cutaneous Leishmaniasis (LCL), borderline disseminated cutaneous Leishmaniasis (BDCL), mucocutaneous leishmaniasis (MCL), mucosal leishmaniasis (ML) and anergic diffuse cutaneous leishmaniasis (ADCL), depending to the species and the host immunoresponse (TCD4+ Th1/Th2). The AVL in spite of the advances of knowledge about the classic form, there are still many gaps in relation to the parasite, L. (L.) chagasi, and the human immunegenitic system. The clinical spectrum of the human infection still needs more precise definition to improve the clinical diagnosis of infected, symptomatic and asymptomatic individuals, as well as suitable treatment for the different forms. Longitudinal field studies are needed for identification of only infected, symptomatic and asymptomatic individuals. Long-term follow up for identification of the clinical immunological patterns of the human infection by L. (L.) chagasi is also needed. The human immune response to infection by L. (L.) chagasi has had more attention in the classical form than in the symptomatic and/or sub clinical forms, in which immunological resistance needs more knowledge. Experimental models for AVL are usually made in hamsters and mice, which data are not fully transferred to man due to philogenetic distance, which make necessary the development of a suitable experimental model closer to man. The Cebus apella, has shown potentially a viable model for in vitro immune response studies using experimental infection in peritoneal macrophages for AVL and ACL species of Leishmania in Brazil. The models of non-human primates, in vivo and in vitro, may be useful to immunopathogenical studies either for AVL or ACL. The project aim the characterization of role the Langherans cells in the CD4/CD8 immune response in the different clinical forms of the Brazilian ACL and different species in the immunopathogenetics modulation; as well as characterization of the clinical and immunological spectrum of the human infection by Leishmania (L.) chagasi in the Brazilian Amazon region, together with the humoral and cellular immune response of the infected individuals. It also proposed the evaluation of the susceptibility of the Cebus apella as experimental model for experimental visceral leishmaniasis, Leishmania (L.) chagasi, and cutaneous leishmaniasis by Leishmania (V.) braziliensis e L. (L.) amazonensis. ln relation to murine experimental model we proposed the kinetic analyses of Langherans cells interaction with the CD4+/CD8+ immune response in mice BALB/C e C57BL/6 by L. (V.) braziliensis and L. (L.) amazonensis isolated from different clinical of ACL. Mechanisms of resistance and susceptibility associated to the innate immune response of peritoneal macrophages from infected neotropicals primates with Leishmania (V.) braziliensis, L. (L.) amazonensis and L. (L.) chagasi will also be studied. (AU)
