The parasite burden was maximal at 72 h post infection (h.p.i.) for THP-1 cells, while it was still increasing at 120 h.p.i. for murine macrophages. Since in both cases the infection with L peruviana affected cell viability, we recommend evaluating any leishmanicidal activity at 72 h.p.i. Amphotericin B reduced Leishmania infection by 50% at concentrations of 0.1 mu M in THP-1 and murine macrophages at 72 h.p.i. Our results demonstrate that amastigotes of L. peruviana can infect THP-1 cells and murine macrophages and indicate the suitability of this model to screen compounds for leishmanicidal activity. specialized THP-1 Murine macrophages Leishmania Leishmania peruviana Leishmanicidal Amphotericin B 052 122 4 353-356 2009 0014-4894 https://www.documentation.ird.fr/hor/fdi:010046220 10.1016/j.exppara.2009.05.005 0014-4894 [F B010046220] https://www.documentation.ird.fr/hor/fdi:010046220 https://www.documentation.ird.fr/intranet/publi/2009/07/010046220.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2009-07-24 2017-08-23 fdi:010046220 fre
