TFAM and frontotemporal dementia: We compared protein levels between each NDD and controls, revealing significant associations between 14–3-3 zeta protein and AD, DLB and FTD/VD cases, synaptophysin protein and PD, DLB, FTD/VD and PSP cases, TFAM protein and DLB and FTD/VD cases and 14–3-3 beta and TRKB proteins with PD cases (STable 1a).
