Figure 1 shows 3H-MK-6240 autoradiography, pSer202/pThr205 tau immunofluorescence (AT8), and X-34 stain of fibrillar aggregates in sections of temporal and frontal cortex from a CTE case with Thal Phase 1 and Braak NFT Stage III (case six, Table 1), and positive control sections of temporal cortex from a typical AD case with Braak NFT Stage VI. This evidence concerns the gene MAPT and Alzheimer disease.
