FTLD-PSP and FTLD-MAPT cases had a modest burden of Iba1- and CR3/43-positive microglia and a low burden of CD68-positive microglia, similar to controls in most regions (Fig. 5g–i), although in TW FTLD-MAPT cases had a higher burden of CD68-positive microglia compared with controls (Fig. 5g). The gene discussed is AIF1; the disease is supranuclear palsy, progressive, 1.
