Interestingly, when focusing on areas with minimal/mild tau pathology [e.g. PSP Case 4 (lumbar cord level) and PSP Case 8 (cervical/lumbar cord level)], there were no tau-positive inclusions in the neurons (sometimes, only a few tau-positive threads were present in the neuropil); however, tau deposits were clearly evident in the corresponding peripheral nerves (Table 2 and Supplementary Fig. 2). The gene discussed is MAPT; the disease is supranuclear palsy, progressive, 1.
