BackgroundAuto-antibodies with specificity to self-antigens have been implicated in a wide variety of neurological diseases, including Parkinson's (PD) and Alzheimer's diseases, being sensitive indicators of neurodegeneration and focus for disease prevention. Of particular interest are the studies focused on the auto-immune responses to amyloidogenic proteins associated with diseases and their applications in therapeutic treatments such as vaccination with amyloid antigens and antibodies in PD, Alzheimer's disease and potentially other neurodegeneration ailments.Methodology/principal findingsGenerated auto-antibodies towards the major amyloidogenic protein involved in PD Lewy bodies--α-synuclein and its amyloid oligomers and fibrils were measured in the blood sera of early and late PD patients and controls by using ELISA, Western blot and Biacore surface plasmon resonance. We found significantly higher antibody levels towards monomeric α-synuclein in the blood sera of PD patients compared to controls, though the responses decreased with PD progression (PConclusions/significanceOur findings may suggest the protective role of autoimmunity in PD and therefore immune reactions towards PD major amyloid protein--α-synuclein can be of value in the development of treatment and diagnostic strategies, especially during the early disease stages.
