The addition of extrinsic recombinant IGF-I to cultures at a physiological concentration induces the proliferation of various species of Leishmania promastigotes and axenic amastigotes [13-15], promotes an increase in macrophage arginase-1 (ARG1) expression as well as in Leishmania arginase (Larg), in vitro [16, 17], and induces a significant increase in the lesion size and the number of viable parasites at the lesion site in experimental models [18].

We have previously shown that adding physiological concentrations of extrinsic IGF-I into cultures induces proliferation of different species of Leishmania promastigotes and axenic amastigotes, which is an effect that is not observed with IGF-II despite its high similarity to IGF-I [19, 20].

Fortunately, in leishmaniasis a close correlation exists between the in vitro and in vivo results (2), because the test parasite is the disease-producing organism in human (amastigote) and these are maintained in vitro as axenic amastigotes and in macrophage culture presenting a semi- in vivo condition.
