CRIPTO3 and red-green color blindness: Comparing cases with underlying tau pathology, FTLD-Picks and FTLD-CBD cases had similar burdens of each microglial phenotype in each region, whereas FTLD-Picks cases had a higher burden of CD68-positive microglia in TW and TG, and CR3/43-positive microglia in all regions, compared with FTLD-PSP cases (Fig. 5g, h).
