PLTP and Alzheimer disease: This panel contained proteins associated with FTD (i.e., GZMB, MMP7, CCL11, NPDC1, PLTP, and APEX1; Supplementary Fig. 3) but also proteins associated with AD (i.e., ABL1, ENO2, ITGB2, SMOC2, and THOP1; Supplementary Fig. 3), as also reported in our previous AD focused PEA study [29].
