The mechanism associated with phagocytosis in Leishmania infection remains poorly understood. Here, we describe methods to evaluate the early events occurring during Leishmania interaction with the host cells.

Here we study implications of Leishmania-host interaction by exploring Leishmania-infected dendritic cells migration. The differentiation and infection of dendritic cells, migration analysis, and the evaluation of adhesion complexes and actin dynamics are described. This method can be applied to other host cell migration studies when infected with Leishmania or other intracellular parasite species.

Dendritic cells (DCs) are essential components of innate immunity against Leishmania infection. The mechanisms underlying the complex interaction between DCs and Leishmania remain poorly understood. Here, we describe methods to evaluate how Leishmania infection affects the immunobiological function of human DCs, such as migration-related and costimulatory molecule expression.
