Plasma and cerebrospinal fluid proteomics reveal distinct patterns of senescence and neuropathology in aging rhesus macaques.
Aging is the primary risk factor for neurodegenerative disease, yet the protein signatures that distinguish physiological brain aging from pathological decline remain incompletely defined in translational models. Using the targeted NULISAseq proteomic platform, we profiled cerebrospinal fluid (CSF) and plasma from 66 r...
