Overlap of the identified proteins in Alzheimer’s disease (AD), control samples and CSF proteome. (A) Overlap of the proteins identified in post-mortem hippocampal tissue specimens from AD patients and age-matched healthy controls. AD and control pools (n = 3) were analysed in triplicates. (B) Overlap of AD and control proteins with literature-based CSF proteome . The comparison reveals that 40 AD-specific proteins identified in the current study were also present in the CSF database.
