Abstract

Parkinson's disease (PD) may be initiated or precipitated by endogenous toxins with a structure similar to 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine in genetically-predisposed individuals. Nicotinamide N-methyltransferase (NNMT) catalyzes N-methylation of nicotinamide and other pyridines to form pyridinium ions. The protein amount of NNMT was measured in the lumbar cerebrospinal fluid of PD patients by immunoblot analysis using anti-human NNMT antibody. In younger (65 years old or younger) PD patients, the relative level of NNMT protein was significantly higher than that in younger controls. The NNMT protein was significantly affected by aging: the amount decreased along with aging in PD patients. These findings suggested that excess NNMT in the central nervous system might be implicated in the PD pathogenesis.
