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). The gene discussed is LRRK2; the disease is Alzheimer disease.
