MAPT and Alzheimer disease: Of the 59 CSF proteins associated with CSF biomarkers of core AD pathology that we report, 28 were also measured with the SOMAscan in that prior study; of those, 22 proteins (i.e., 78.6% overlap) were correlated with CSF Aβ1–42, tau, and/or P-tau [66], confirming part of our observations in an independent cohort and using a different technology.
