Figure 3. TLR4 and MyD88 regulate foam cell formation in response to agLDL but not acLDL.
(A-D) Foam cell formation in response to agLDL was analyzed by confocal microscopy of (A) WT, (B) Tlr4−/− and (C) Myd88−/− BMMs treated with A546-agLDL for 12 hr, fixed and neutral lipids stained using LipidTOX green. (D) Confocal images were used to quantify LipidTOX intensity per field. (E-H) Foam cell formation in response to acLDL was analyzed by confocal microscopy of (E) WT, (F) Tlr4−/− and (G) Myd88−/− BMMs treated with acLDL (100 μg/mL) for 12 hr, fixed and neutral lipids stained using LipidTOX green. (H) Confocal images were used to quantify LipidTOX intensity per field. Data were compiled from 3 independent experiments per condition. Error bars represent the standard error of the mean (SEM). *** p ≤ 0.001. Scale bars 20 μm.
