Plasma proteomics of mice treated with BACE inhibitors Version 1
External LinkThe Beta-secretase BACE1 is a central drug target for Alzheimer’s disease. Clinically tested, BACE1-directed inhibitors also block the homologous protease BACE2. Yet, little is known about physiological BACE2 substrates and functions in vivo. To discover potential BAC2 substrates in plasma, mice were treated with a non-specific BACE inhibitor (Cpd89) and a BACE1 preferring inhibitor (LY2811376). Plasma proteomics using DIA showed a reduced abundance of soluble FLT4 (sVEGFR3) for the non-specific inhbtor but not for the BACE1 preferring inhibitor. Conclusively, sVEGFR3 is a potential marker for BACE2 inhibition in plasma.

The beta-secretase BACE1 is a central drug target for Alzheimer’s disease. Clinically tested, BACE1-directed inhibitors also block the homologous protease BACE2. Yet, little is known about physiological BACE2 substrates and functions in vivo. Here, we performed glycoprotein enrichment and subsequent discovery proteomics to identify substrates of the protease BACE2 in plasma of mice. Therefore, we analysed plasma from BACE2 KO, BACE1/2 double KO and WT controls, as well as BACE1 KO with a separate ...
