Inflammation is associated with oxidative stress and local generation of lipid peroxidation-derived aldehydes, such as 4-hydroxy-trans-2-nonenal (HNE). In most tissues, HNE is readily conjugated with glutathione and presently it is unknown whether glutathionyl-HNE (GS-HNE) plays a functional role in inflammation.

Oxidation of lipids generates large quantities of highly reactive alpha,beta-unsaturated aldehydes (enals). Enals and their protein adducts accumulate in the tissues of several pathologies. In vitro, low concentrations of enals such as HNE (4-hydroxy trans-2-nonenal) affect cell signaling whereas high
