Moreover, Leishmania infection triggered cell proliferation as was evidenced by increased expression of cyclin A and p-RPS6. mTOR activation during Leishmania infection resulted in reduced expression of M1 macrophage markers (eg, ROS, NO, iNOS, NOX-1, IL-12, IL-1β and TNF-α), and increased expression of M2 macrophage markers (eg, arginase-1, IL-10, TGF-β, CD206 and CD163).
