Proteome profiling of brain tissue from multiple system atrophy patients and from controls


ABSTRACT: Human brain tissue was collected post mortem from patients diagnosed with multiple system atrophy (n=45) and from controls (n=30) in order to perform a comparative quantitative proteome profiling of tissue from the prefrontal cortex (Broadman area 9).

<h4>Background</h4>Multiple system atrophy (MSA) is a rare, progressive, neurodegenerative disorder presenting glia pathology. Still, disease etiology and pathophysiology are unknown, but neuro-inflammation and vascular disruption may be contributing factors to the disease progression. Here, we performed an ex vivo deep proteome profiling of the prefrontal cortex of MSA patients to reveal disease-relevant molecular neuropathological processes. Observations were validated in plasma and cerebrospi  ...[more]
