AB Many nervous system pathologies are associated withincreased levels of apolipoprotein D (ApoD), a lipocalinalso expressed during normal development and aging.An ApoD homologous gene inDrosophila, Glial Lazarillo,regulates resistance to stress, and neurodegeneration in theaging brain. Here we study for the first time the protectivepotential of ApoD in a vertebrate model organism. Lossof mouse ApoD function increases the sensitivity tooxidative stress and the levels of brain lipid peroxidation,and impairs locomotor and learning abilities. HumanApoD overexpression in the mouse brain produces oppositeeffects, increasing survival and preventing the raise ofbrain lipid peroxides after oxidant treatment. Theseobservations, together with its transcriptional up-regulationin the brain upon oxidative insult, identify ApoD as an acuteresponse protein with a protective and therefore beneficialfunction mediated by the control of peroxidated lipids.Key words: learning, lipid peroxidation, lipocalin, locomotorbehavior, paraquat, oxidative stress.
