From: Preventive immunization of aged and juvenile non-human primates to beta-amyloid
Analysis of YKL40 release There were significantly higher concentrations of YKL40 in (A) cerebrospinal fluid (CSF) and (B) plasma in aged (n = 10) than in juvenile (n = 8) animals at baseline in both fluid compartments. No significant changes were seen in the CSF after immunization (Aged, n = 9; juvenile, n = 8). Mean ± SD.
