Schematic summary of the hypothesis. Contactin-2 interacts with beta-secretase 1 (BACE1) and amyloid precursor protein (APP). Binding of contactin-2 with APP leads to APP processing and amyloid beta (Aβ) peptide release. Based on our data, we hypothesize that a decrease in contactin-2 levels (shown by a thick dark blue arrow) in AD might be a cellular protective mechanism to reduce the binding of contactin-2 with APP and thus subsequently lowering production of Aβ. Correlations of contactin-2 with total tau (tTau)/phosphorylated tau (pTau) and neurogranin suggest possible interactions among these molecules or their involvement in common pathogenic mechanisms. Solid single/double headed arrows indicate correlations/interactions between two proteins and dashed arrow indicates no correlation. CSF cerebrospinal fluid
