The proportion of calbindin-negative DG granule neurons was found to increase with Braak stage of AD and was significantly higher than in Creutzfeldt-Jakob disease, argyrophilic grain disease, frontotemporal lobar degeneration-TDP types A and B, but not compared to frontotemporal lobar degeneration-Tau Pick’s disease type (Stefanits et al., 2014). Here, CALB1 is linked to argyrophilic grain disease.
