gamma -secretase (100 nM BMS 299897 and 250 nM DAPT)
Using more specific inhibitors, we ruled out the involvement of gamma -secretase (100 nM BMS 299897 and 250 nM DAPT) or matrix metalloproteinases 1, 2, 3, 7, 9, 14, and 17 (0.1–1 μM batimastat and marimastat), as their inhibitors failed to alter A beta O release

Alzheimer's disease (AD) is a degenerative brain disease and the most common cause of dementia, affecting approximately 47 million people worldwide. Updated in 2015, this poster summarizes the structural and functional changes observed in the progression of this neurodegenerative disease, as well as classic AD drug targets.
