Our objective was to evaluate the CSF phospho-Tau181/total-Tau (p/t-Tau) ratio to distinguish between the two main forms of frontotemporal lobar degeneration (FTLD): FTLD with TDP-43 (FTLD-TDP) and FTLD with Tau inclusions (FTLD-Tau).
-
The lack of readily available biomarkers is a significant hindrance toward progressing to effective therapeutic and preventative strategies for Alzheimer's disease (AD).
-
To determine whether apparent involvement of DYRK1A in Alzheimer's disease (AD) pathology makes it a candidate plasma biomarker for diagnosis, we developed a method to quantify plasma DYRK1A by immunoblot in transgenic mouse models having different gene dosages of Dyrk1a, and, consequently, different relative protein expression.

Using a targeted proteomics approach, we confirmed previous findings for a subset of markers, defined longitudinal performance of our panel of markers, and established a flexible proteomics method for robust multiplexed analyses.
