SFRP1 and early-onset autosomal dominant Alzheimer disease: Among the differentially expressed proteins, there were proteins involved either in the neurogenic process (e.g. GDF11) or in Alzheimer’s disease (e.g. LRRK2, RCAN1, NTRK2), or in both neurogenesis and Alzheimer’s disease (e.g. CREBBP, SFRP1, IL1RAP).
