Chemokines in Leishmaniasis: Map of cell movements highlights the landscape of infection and pathogenesis.

Pathogen interactions with the host immune response components are critical for establishing protective immunity and pathological responses against Leishmania parasites. A predominant proinflammatory profile associated with enhanced phagocytosis trigger a cell-mediated immune response that is relevant to infection control. On the other hand, an anti-inflammatory phenotype, correlated with a predominant modulated/regulatory response, favors intracellular proliferation of Leishmania parasites and disease progression. In this context, chemokines play an important role in determining cellular composition at inflammatory sites. Leishmania infection induces the expression of various chemokines and chemokine receptors in the mammalian host, which can subvert the host immune responses. Indeed, the balance and dynamic changes in cytokines and chemokines may control or predict the disease outcome. In this review, we address our current knowledge regarding the chemokines and chemokines receptors' role in the immunopathogenesis of Tegumentary and Visceral Leishmaniasis.
