PEPTOIDS AS A BIOMARKER FOR PARKINSON'S DISEASE

Costly methods of diagnosis� such as the SPECT scan or the PET scan are used for the indication of Parkinson's Disease. However, in early Parkinson's Disease a far less costly and relatively non-invasive biomarker would be preferable. Researchers� identified a peptoid called PD2, which binds significantly higher levels of IgG3 antibody in those people with Parkinson's Disease. The PD2 peptoid was found to be� 68% accurate in identifying Parkinson's Disease, which is less accurate than existing methods. However, PD2 was 84% accurate in identifying new cases of Parkinson's Disease. It is new cases of Parkinson's Disease that existing methods are not so accurate with. PD2 levels are also positively correlated with the United Parkinson's Disease Rating Scale score, which is the primary symptom questionnaire for Parkinson's Disease. So the researchers concluded that PD2 may be useful for the diagnosis of early Parkinson's Disease.
