Of the CTE cases examined in this study, only case 6 (Low AD Neuropathologic Change: A1, B2, C0, Table 1) had a laminar pattern of 3H-MK-6240 autoradiography signal that was distinct in the superior temporal cortex and less so in the dorsolateral frontal cortex, spatially corresponding to AT8-immunoreactive and X-34 labeled tau lesions on adjacent sections, and was not present in the self-blocked sections. The gene discussed is MAPT; the disease is Alzheimer disease.
