Natural antibodies (nAbs) against aggregation-prone proteins have been found in healthy normal subjects. These proteins likely have a pathogenetic role in neurodegenerative diseases of ageing. They include the amyloid beta (A beta) protein which may play an important role in Alzheimer's dementia (AD), and alpha-synuclein, a major determinant of Parkinson's disease (PD). We measured nAbs to A beta in a group of Italian patients with AD, vascular dementia, non-demented PD patients and healthy elderly controls. We found that A beta antibody levels in AD were similar to age- and sex-matched controls, but contrary to our expectations, they were significantly reduced in PD. This may identify patients that could be more prone to amyloid aggregation.

Abstract
Natural antibodies (nAbs) against aggregation-prone proteins have been found in healthy normal subjects. These proteins likely have a pathogenetic role in neurodegenerative diseases of ageing. They include the amyloid beta (A beta) protein which may play an important role in Alzheimer's dementia (AD), and alpha-synuclein, a major determinant of Parkinson's disease (PD). We measured nAbs to A beta in a group of Italian patients with AD, vascular dementia, non-demented PD patients and healthy elderly controls. We found that A beta antibody levels in AD were similar to age- and sex-matched controls, but contrary to our expectations, they were significantly reduced in PD. This may identify patients that could be more prone to amyloid aggregation.File | Dimensione | Formato | |
