PEBP1 and Alzheimer disease: 231 proteins were significantly altered between some AD phenotypes and neurologically intact controls, where 11 potential biomarkers identified in the OB region (Serum albumin, 14-3-3 protein epsilon, Isoform 3 of Inter-alpha-trypsin inhibitor heavy chain H4, Antithrombin-III, Hemopexin, C4b-binding protein alpha chain, Gamma enolase, Phosphatidylethanolamine binding protein 1, Glial fibrillary acidic protein, Neuronal pentraxin-1, and Neurofascin) (see Online Resource 5) have already been proposed for their potential usefulness in AD diagnosis [23, 24, 47].
