Web3 mrt. 2014 · The increased expressions of LDL transcytosis-related proteins (LDL receptor and caveolin-1, -2) stimulated by TNF-α were also blocked by both NF-κB inhibitors and PPAR-γ inhibitors. TNF-α promotes atherosclerosis by increasing the LDL transcytosis across endothelial cells and thereby facilitating LDL retention in vascular walls. WebThe LDL transcytosis was normalized to that obtained after incubating 50 μg·mL −1 FITC-LDL for 3 h. As shown in Figure 3A, exposure to CRP for 3 h significantly increased LDL transcytosis and, in the same model, CRP increased intracellular ROS levels (Figure 3B), with peak production at about 5 min after the addition of CRP. fnf too slow lyrics
