[Retracted] Pentoxifylline Can Reduce the Inflammation Caused by LPS after Inhibiting Autophagy in RAW264.7 Macrophage Cells

Figure 4

Morphological observation of autophagy after PTX stimulation. (a) Fluorescence microscope observation of autophagy bodies (yellow) and autophagy lysosomes (red) affected by PTX concentration in cells and the GFP-RFP-LC3-transfected RAW264.7 cells treated with different PTX (0, 0.2, and 0.5 mg/mL). (b) Electron microscopy of autophagic bodies. RAW264.7 cells treated with different PTX (0, 0.2, and 0.5 mg/mL) were visualized by transmission electron microscopy. In control roots, few vesicles are apparent within the vacuole as they are immediately degraded. The autophagic bodies (big arrows) and autophagic lysosomes (small arrows) could be clearly observed.
