PG - 3823-31 LID - 10.1016/j.febslet.2008.10.015 [doi] AB - Palmitoyl-protein thioesterase-1 (PPT1) deficiency causes infantile neuronal ceroid lipofuscinosis (INCL), a devastating childhood neurodegenerative storage disorder. We previously reported that neuronal apoptosis in INCL is mediated by endoplasmic reticulum-stress. ER-stress disrupts Ca(2+)-homeostasis and stimulates the expression of Ca(2+)-binding proteins. We report here that in the PPT1-deficient human and mouse brain the levels of S100B, a Ca(2+)-binding protein, and its receptor, RAGE (receptor for advanced glycation end-products) are elevated. We further demonstrate that activation of RAGE signaling in astroglial cells mediates pro-inflammatory cytokine production, which is inhibited by SiRNA-mediated suppression of RAGE expression. We propose that RAGE signaling contributes to neuroinflammation in INCL.
