by fibrillar A . To explore this possibility, primary rat astrocytes were used to test IDE levels after exposure to soluble or fibrillar A . After treatment with 5 M fibrillar A , IDE protein and transcripts increased 2-fold as detected by WB, immunofluorescence and RT-PCR compared to soluble A or control cultures. Conclusions: Our results suggest that the defective clearance of A due to IDE lower expression or activity is not an accelerating factor in Tg2576 mice amyloid deposition. Moreover, IDE overexpression associated to late-stages of the neuropathologic process in this animal model may be part of an inflammatory response, suggesting a new role for IDE in the brain that deserves future investigation.
