The role of inflammatory processes in the brains of Alzheimer's Disease (AD) patients has recently attracted considerable interest. Indeed, the only demonstrated effective therapy for AD patients is long-term treatment with non-steroidal anti-inflammatory drugs (NSAIDs). The mechanistic basis of the efficacy of NSAIDs in AD remains unclear. However, the recent recognition that NSAIDs can bind to and activate the nuclear receptor peroxisome proliferator-activated receptor gamma (PPAR gamma), has offered an explanation for the action of these drugs in AD. PPAR gamma activation leads to the inhibition of microglial activation and the expression of a broad range of proinflammatory molecules. The newly appreciated anti-inflammatory actions of PPAR gamma agonists may allow novel therapies for AD and other CNS indications with an inflammatory component. (C) 2001 Elsevier Science Inc.
