Figure 3. Activated protein C (APC) and leukocyte inflammation.
Inflammatory signaling by leukocytes is driven in part via protein kinase C (PKC) signaling to generate reactive oxygen species (ROS) through NADPH oxidase, resulting in development of an activated inflammasome and/or formation of NETs. APC inhibits leukocyte inflammatory processes in a receptor-dependent manner, requiring Mac-1 (CD11b/CD18), endothelial protein C receptor (EPCR), PAR1 and PAR3, inducing intracellular cytoprotective signaling.
