- Clinical differentiation between parkinsonian syndromes (PS) remains a challenge despite well-established clinical diagnostic criteria. Specific diagnostic biomarkers have yet to be identified, though in recent years, studies have been published on the aid of certain brain related proteins (BRP) in the diagnosing of PS. We investigated the levels of the light subunit of neurofilament triplet protein (NF-L), total tau and phosphorylated tau, amyloid-β(1-42), and the soluble α- and β-cleaved fragments of amyloid precursor proteins in a cohort of patients with various PS.

- Parkinson's disease (PD) and atypical parkinsonian disorders (APD), including multiple system atrophy (MSA), progressive supranuclear palsy (PSP), and corticobasal degeneration (CBD), are a group of neurodegenerative diseases sharing many similar signs and symptoms but distinguished by their particular clinical features, treatment response, prognosis and mortality. The differential diagnosis may be challenging, especially in early disease stages. Considering the importance of an accurate diagnosis both for clinical management and for research, new diagnostic tools are needed. In this study, we investigated 56 PD, 42 MSA, 39 PSP, 9 CBD patients, and 24 healthy controls. After screening the cerebrospinal fluid (CSF) proteome using surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF MS), we identified 4 proteins (ubiquitin [mass-to-charge ratio (m/z) 8590], beta2-microglobulin [m/z 11730], and 2 secretogranin 1 [chromogranin B] fragments [m/z 7260 and m/z 6250]) that differentiated healthy controls and PD patients from patients with APD. However, they could not differentiate PD patients from controls. As none of these changes were APD subgroup-specific, they most likely reflect the intensity and/or extent of the neurodegenerative process in general.

Forskningsöversikt (refereegranskat)abstract
- Parkinsonian disorders such as Parkinson's disease (PD), multiple system atrophy (MSA), progressive supranuclear palsy (PSP), and corticobasal degeneration (CBD), are a large group of common neurodegenerative diseases. The initial differential diagnosis can be extremely challenging with major implications for prognosis. The 42 amino acid fragment of amyloid-beta (Abeta42), neurofilament light chain (NFL), neurofilament heavy chain (pNFH), tau protein, glial fibrillary acidic protein (GFAP), neuron specific enolase (NSE), S-100B protein, and myelin basic protein (MBP) are brain related proteins (BRP) present in neurons and glia cells. They are released in the cerebrospinal fluid (CSF) after brain tissue damage caused by a variety of neurological diseases, including the parkinsonian disorders. A review of the literature shows that, carefully interpreted, the CSF levels of BRP can be of value in the differential diagnosis of parkinsonian disorders.

- BACKGROUND: Neurofilaments are major structural elements of neuronal cells. The light subunit of neurofilament triplet protein (NFL) has been shown to be increased in several neurological diseases (e.g. vascular, infectious, neurodegenerative), indicating axonal damage. METHODS: In this study we analyzed the NFL levels in all (N=35) available cerebrospinal fluid (CSF) samples from a clinical trial in Huntington's disease (HD) and compared them to age and gender matched controls. RESULTS: The CSF-NFL levels were significantly higher in HD subjects compared with age and genders matched controls, and were correlated with scores on the Unified Huntington's Disease Rating Scale Total Functional Capacity assessment. The potential of CSF-NFL levels as a disease activity marker in HD needs to be further investigated.
