Pu-erh Tea Ameliorates Atherosclerosis Associated with Promoting Macrophage Apoptosis by Reducing NF-κB Activation in ApoE Knockout Mice

Figure 1

Pu-erh tea consumption could inhibit the progress of atherosclerosis by promoting macrophage apoptosis. (a-b) Oil Red O (ORO) staining to detect lipid deposition and triple immunofluorescence to detect the apoptosis of macrophages in the plaques, magnification ×40 (a) or ×100 (b), bar = 200 μm. (c–f) Plaque lesion area, ORO staining positive rate, CD68 positive rate, and apoptosis rate of macrophages in the plaque of ApoE null mice. .
