Brain energy metabolism and multiple sclerosis: progress and prospects

Area of Science:

• Neuroscience
• Immunology
• Metabolomics

Background:

• Multiple sclerosis (MS) is an autoimmune disease causing nerve pain and paralysis.
• Current MS diagnosis relies on clinical experience due to a lack of specific biomarkers.
• Existing treatments offer limited impact on disease progression and disability.

Purpose of the Study:

• To review recent advances in metabolomic studies concerning MS.
• To focus on the role of energy metabolism fluctuations in MS pathogenesis.
• To explore potential new diagnostic and therapeutic strategies for MS.

Main Methods:

• Review of current literature on metabolomics in multiple sclerosis.
• Analysis of studies investigating energy metabolism in the central nervous system (CNS) of MS patients.
• Examination of findings related to mitochondrial and cytosolic energy failure.

Main Results:

• Inflammation in MS patients' CNS can lead to energy failure in mitochondria and cytosol.
• Metabolomics studies reveal impaired oxidative phosphorylation and altered aerobic glycolysis in MS.
• Evidence points to energy metabolism disruption as a significant aspect of MS pathogenesis.

Conclusions:

• Understanding CNS energy metabolism alterations offers new insights into MS complexity.
• Metabolomic approaches may identify novel biomarkers for MS diagnosis.
• Targeting energy metabolism dysfunction presents a promising therapeutic avenue for MS.
