Alzheimer's disease: low levels of peptide alpha-amidation activity in brain and CSF.

Carboxyl terminal alpha-amidation confers biologic activity to many neuropeptides. Levels of alpha-amidating activity, peptidyl-glycine alpha-amidating monooxygenase ( PAM), were reduced in the CSF of patients with dementia of the Alzheimer type (DAT) compared with healthy, age-matched controls. Repeat lumbar puncture data revealed a decline in CSF PAM activity of approximately 16% per year in DAT patients. Of the cerebral cortical regions examined, only the temporal pole showed reduced PAM activity in patients with Alzheimer's disease (AD) compared with controls. These studies may indicate selective dysfunction of neurons which normally synthesize biologically active, alpha-amidated peptides in the CNS of AD patients.[1]
