Multiple system atrophy: advances in pathogenesis and emerging therapeutic strategies

Area of Science:

• Neuroscience
• Neurology
• Pathology

Background:

• Multiple system atrophy (MSA) is a sporadic, adult-onset neurodegenerative disorder.
• Symptoms include autonomic dysfunction, Parkinsonism, and cerebellar impairment.
• Current treatments offer symptomatic relief but do not halt disease progression.

Purpose of the Study:

• To review recent advancements in understanding Multiple System Atrophy (MSA) pathogenesis.
• To explore the role of alpha-synuclein (α-Syn) in MSA development.
• To provide insights into future research and clinical trials for MSA.

Main Methods:

• Literature review of recent epidemiological, genetic, and preclinical studies on MSA.
• Analysis of research on α-Syn aggregation, neuroinflammation, and mitochondrial dysfunction.
• Overview of current clinical trials for MSA therapies.

Main Results:

• α-Syn plays a central role in MSA pathogenesis.
• Key findings involve α-Syn aggregation, neuroinflammation, neurotrophic support, and mitochondrial dysfunction.
• Significant progress has been made in understanding MSA's early pathological events.

Conclusions:

• Understanding early pathological events in MSA is crucial for developing effective therapies.
• Targeting α-Syn aggregation and related pathways shows therapeutic potential.
• Further research and clinical trials are needed to slow MSA progression.
