DLG4 and supranuclear palsy, progressive, 1: Analyses of colocalization coefficient (Fig. 2c) confirmed the notably increased binding of AD TauO and DLB TauO to postsynaptic marker (p < 0.0001), whereas PSP TauO bound to postsynaptic marker was slightly higher than presynaptic marker without reaching significance (p = 0.1271), suggesting that TauO from AD and DLB, but not PSP, colocalize with postsynaptic marker, PSD-95.
