cerebrospinal fluid |
development of assay for cerebrospinal fluid beta-secretase-1 activity with sensitivity down to 1 pM of recombinant enzyme. Endogenous secretase-1 enzyme appears to exist as a C-terminally truncated protein. A small cohort of human subjects displays age-dependent increase in cerebrospinal fluid beta-secretase-1 activity. In Alzheimer's disease subjects, a significant decline in age-adjusted cerebrospinal fluid beta-secretase-1 activity is observed |
