Murine bone marrow-derived macrophages infected with Mtb H37Rv for 24hr and examined by confocal microscopy.
A, B. Expression of Adfp in (A) control cells versus (B) Mtb-infected cells.
C, D. Expression of Acsl1 in (C) control and (D) Mtb-infected macrophages.
E, F. Expression of SapC in (E) control and (F) Mtb-infected macrophages. Blue, nuclei, Green: antigens. Human PBMC-derived macrophages were infected by Mtb H37Rv for 4 days, and the antigens were detected by confocal microscope.
G, H. ADFP is expressed and is associated tightly with lipid droplets (G) control and (H) Mtb-infected macrophages. Lipid droplets were observed in both uninfected and infected human PBMC-derived macrophages.
I, J. ACSL1 is also detected in association with lipid droplets, (I) control and (J) Mtb-infected macrophages.
K, L. SapC is expressed and localizes throughout the cytoplasm (K) control and (L) Mtb-infected macrophages. Blue: nuclei, red: antigens, green: lipid droplets.
