Kamalian et al. presents a deep proteomic and peptide-level analysis of matched cerebrospinal fluid and plasma from cognitively normal adults (From 18- to 83-year-olds). This study reveals distinct molecular signatures of normal aging and uncovers age-associated cleavage and phosphorylation events in key proteins such as APP, APOE, and NRXN1.
