LRP8 and Alzheimer disease: Using IHC and MP-IHC for deep phenotyping of ErC in a Braak stage I/Thal phase I non-AD case (Fig. 5), we observed that Dab1, pLIMK1Thr508, and pPSD95Thr19 tend to accumulate together with pTauSer202/Thr205 within the soma of the same L2 ApoER2-expressing stellate-shaped neurons and pyramidal neurons (Fig. 5).
