ABSTRACT:
The invention provides a method of preventing, delaying, or reversing the progression of Alzheimer's disease by administering an Aβ42lowering agent to a mammal under conditions in which levels of Aβ42are selectively reduced, levels of Aβ38are increased, and levels of Aβ40are unchanged. The invention provides methods and materials for developing and identifying Aβ42lowering agents. In addition, the invention provides methods for identifying agents that increase the risk of developing, or hasten progression of, Alzheimer's disease. The invention also provides compositions of Aβ42lowering agents and antioxidants, Aβ42lowering agents and non-selective secretase inhibitors, as well as Aβ42lowering agents and acetylcholinesterase inhibitors. The invention also provides kits containing Aβ42lowering agents, antioxidants, non-selective secretase inhibitors, and/or acetylcholinesterase inhibitors as well as instructions related to dose regimens for Aβ42lowering agents, antioxidants, non-selective secretase inhibitors, and acetylcholinesterase inhibitors.
