  • Patent number: 9234038
    Abstract: Disclosed herein are methods of diagnosing, preventing and treating Alzheimer's disease based on the use of an inhibitor for the binding of amyloid-? (A?) to Fc?RIIb, and a method of screening the inhibitor. The inhibitor is selected from the group consisting of an Fc?RIIb protein or a variant thereof, an Fc?RIIb extracellular domain, an anti-Fc?RIIb antibody, an Fc?RIIb-specific peptide and an Fc?RIIb-specific siRNA. The inhibitor reduces the toxic signaling and intracellular translocation of A? and the neurotoxicity, neuronal cell death and memory impairment mediated by A? by inhibiting the binding between A? and Fc?RIIb. Thus, the inhibitor is useful in the diagnosis, prevention and treatment of Alzheimer's disease.
