In Vitro Infections of Macrophage-Like Cell Lines with Leishmania infantum for Drug Screening
The study of in vitro infections is essential to evaluate distinct aspects of Leishmania biology and also invaluable for more meaningful in vitro screening of promising chemical entities. Macrophage-like cells lines from different origins are amenable to Leishmania infection. Cell lines due to their stability and standardization potential are highly valued for their capacity to support reproducible infections and consistent data. In fact, these cells have been a mainstay of leishmaniasis research for more than 40 years. In this context, the human monocytic THP-1 cell line is commonly used as it can be differentiated with phorbol-12myristate-13-acetate (PMA) into macrophages that are susceptible to Leishmania infection. In this section, we will describe generalities concerning the use of cell lines for in vitro Leishmania infection using THP-1 derived macrophages and Leishmania infantum axenic amastigotes expressing luciferase associated to preclinical drug screening as example.
