Parkinson Disease
Conditions
Brief summary
In Parkinson's disease (PD), direct evidence linking inflammation to the harmful activities of alpha-synuclein (a-syn) aggregates, the disease onset, and its progression is still lacking. This translational project aims to reveal the causal relationship between a-syn and inflammation. The investigators will also investigate the mechanisms underlying the beneficial effects of two non-pharmacological approaches, motor exercise and neuromodulation, with particular focus on neuroinflammation and brain-derived neurotrophic factor (BDNF) production. the investigators will investigate the molecular pathways and synaptic alterations underlying disease progression. This will be paralleled by a clinical study, in which clinical assessment will be associated with cerebrospinal fluid (CSF) and blood neurodegeneration and inflammatory biomarkers measures. Then, the investigators will test the hypothesis that intensive exercise and neuromodulation may reduce neuroinflammation and a-syn spreading via the activation of BDNF-related pathways.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| CLINICAL PROFILING OF PD PATIENTS (n=400) | at enrolling | patients will be evaluated by means of validated clinical scales Movement disorders society-unified Parkinson's Disease Rating Scale (min 0- max 260, better clinical conditions has lower scores) |
| MOLECULAR PROFILING OF PD PATIENTS (n=400) | at enrolling | Biomarkers related to axonal damage (total tau (t-Tau), neurofilament light chain, (NfL), and phosphorylated neurofilament heavy chain, (p-NfH), synaptic dysfunction (a-synuclein (a-syn) and neurogranin, (Ng)), neuroinflammation (soluble triggering receptor expressed on myeloid cells 2, sTREM2, and chitinase-3- like protein 1, YKL-40) will be analysed in cerebrospinal fluid (CSF) and blood samples and extracellular vesicles (EVs) (UO1, UO2) (for all the biomarkers, ng/ml). |
| ELECTROPHYSIOLOGICAL PROFILING OF PD PATIENTS (n=400) | at enrolling | Motor evoked potentials (MEPs) from the First Digital Interosseus muscle of the most affected hand of each patient, a brief pattern of iTBS will be applied to promote enhancement of cortical excitability. MEPs size will be then assessed again using single-pulse TMS. |
