Abstract(s)The study of host AMP-activated protein kinase (AMPK) activation during Leishmania infection imposes distinct types of techniques to measure protein expression and activation, as well as to quantify, at transcription and translational levels, its downstream targets. The investigation of host AMPK protein modulation during Leishmania infection should primarily be assessed during in vitro infections using as a host murine bone marrow-derived macrophages (BMMos). The infection outcome is assessed measuring the percentage of infected cells in the context of BMMos. To evaluate AMPK activity during infection, the expression of AMPK phosphorylated at Thr172 as well as the transcription and translational levels of its downstream targets are evaluated by quantitative PCR and immunoblotting. The modulation of AMPK activity in vivo is determined specifically in sorted splenic macrophages harboring Leishmania parasites recovered from infected mice using fluorescent-labeled parasites in the infectious inocolum. The modulation of AMPK activity was assessed by AMPK activators and inhibitors and also using AMPK, SIRT1, or LKB1 KO mice models. The infection outcome in BMMos and in vivo was further determined using these two different approaches. To finally understand the metabolic impact of AMPK during infection, in vitro metabolic assays in infected BMMos were measured in the bioenergetic profile using an extracellular flux analyzer.
