HNRNPK and Alzheimer disease: There was no colocalization between hnRNPs and pTau in dystrophic neurites (Figure 1), although there does appear to be infrequent colocalization with hnRNPs (mostly hnRNP A2B1 and hnRNP K) in neuropil threads and small pTau puncta, predominantly in AD (Figures 3A, 4A, and 5A).
