Theory of Gene Therapy by AAV-PQBP1 (IMAGE) Tokyo Medical and Dental University Caption In Alzheimer's disease state, the nuclear scaffold protein SRRM2 and the synapse-gene regulator PQBP1 are decreased. By increasing PQBP1 in neurons, expression of synapse genes are recovered and cognitive defects are rescued in Alzheimer's patients.
