We have previously shown that CerebrolysinTM (CBL), a neuropeptide mixture with neurotrophic effects, ameliorates the pathology in amyloid precursor protein transgenic (tg) mouse model of AD and 4R tau, however it is unclear if CBL ameliorates the deficits and neuropathology in the mouse model of Pick’s disease over expressing 3R tau. The gene discussed is APP; the disease is Alzheimer disease.
