Immunostaining for p62 (a-c) and hnRNP A3 (d-f) in dentate gyrus (a,d) and CA4 region (b,e) of hippocampus, and in cerebellum (c,f), in cases of FTLD-TDP associated with expansions in C9orf72 gene. There are abundant p62-immunoreactive neuronal cytoplasmic inclusions in dentate gyrus (a) and CA4 region (b) of hippocampus, and in cerebellum (c), though only a small proportion of cells in dentate gyrus show similar appearing hnRNP A3-immunoreactive inclusions (arrowed in d), but none are present in CA4 region (e) or cerebellum (f).
