A Presenilin-1 Mutation Renders Neurons Vulnerable to Isoflurane Toxicity

Abstract

Our results show that the L286V PS1 mutation augments the isoflurane-induced [Ca2+]c increase via calcium release from intracellular stores which, in turn, renders the cells vulnerable to isoflurane neurotoxicity. ROS production was not involved in isoflurane-induced neurotoxicity. Sevoflurane and desflurane, at equivalent exposure to isoflurane, did not induce a similar increase of [Ca2+]c or neurotoxicity in L286V PC12 cells.
