Lipid dysfunction and pathogenesis of multiple system atrophy

Multiple system atrophy (MSA) is a progressive neurodegenerative disease characterized by the accumulation of α-synuclein protein in the cytoplasm of oligodendrocytes, the myelin-producing support cells of the central nervous system (CNS). The brain is the most lipid-rich organ in the body and disordered metabolism of various lipid constituents is increasingly recognized as an important factor ...

Exploring Myelin Dysfunction in Multiple System Atrophy

Multiple system atrophy (MSA) is a rare, yet fatal neurodegenerative disease that presents clinically with autonomic failure in combination with parkinsonism or cerebellar ataxia. MSA impacts on the autonomic nervous system affecting blood pressure, heart rate and bladder function, and the motor system affecting balance and muscle movement. The cause of MSA is unknown, no definitive risk factor...

Altered lipid levels provide evidence for myelin dysfunction in multiple system atrophy

Multiple system atrophy (MSA) is a rapidly-progressive neurodegenerative disease characterized by parkinsonism, cerebellar ataxia and autonomic failure. A pathological hallmark of MSA is the presence of α-synuclein deposits in oligodendrocytes, the myelin-producing support cells of the brain. Brain pathology and in vitro studies indicate that myelin instability may be an early event in the path...

[Multiple system atrophy and autophagy].

Macroautophagy is a dynamic process whereby cytoplasmic molecules are sequestered within autophagosomes. There exist two groups of mammalian autophagy-related gene (Atg) 8 homologues (LC3 and GABARAPs), which play essential role in autophagosomal formation. We determined whether Atg8 homologues are affected in Lewy body disease (LBD) and multiple system atrophy (MSA). The level of LC3 was incre...

Multiple system atrophy.

Multiple system atrophy (MSA) is an adult-onset sporadic progressive neurodegenerative disorder of unknown etiology. It is clinically characterized by the variable combination of autonomic failure, parkinsonism, cerebellar ataxia, and pyramidal signs. The present review summarizes up-to-date knowledge on the clinical diagnosis and molecular pathology of MSA. We also review the role of additiona...
