Lipid peroxidation, or lipid oxidation, is a complex chemical process that leads to oxidative degradation of lipids, resulting in the formation of peroxide and hydroperoxide derivatives. It occurs when free radicals, specifically reactive oxygen species (ROS), interact with lipids within cell membranes, typically polyunsaturated fatty acids (PUFAs) as they have carbon-carbon double bonds.Thus, we have found that a cascade of diverse mediators that include a lipid (LTB 4) and its chemoattractant receptor (BLT1), a cytokine (IL-1β), and chemokines active on CCR1 and CXCR2 collaborate to control neutrophil trafficking into the joint and the development of arthritis in this model.As mentioned above, lipid peroxidation is a prevalent feature of a number of disease states and a key initiator of the ferroptotic cascade.
