Аннотация:The repair of myelin, termed remyelination, is a regenerative process that occurs within the central nervous system in conditions such as multiple sclerosis. Remyelination is enabled by oligodendrocytes that mature from oligodendrocyte precursor cells. Many factors influence the biology of oligodendrocytes and their capacity to reform myelin, and considerable evidence now implicates the extracellular matrix within the injured central nervous system as a major modifier of remyelination. Herein, we review current knowledge of components of the brain extracellular matrix that are beneficial or inhibitory for oligodendrocyte recruitment and maturation, and for their capacity to remyelinate where evidence exists. We highlight the detrimental roles of the chondroitin sulfate proteoglycans in remyelination and discuss approaches to alter the brain extracellular matrix for the wellbeing of oligodendrocytes and their capacity for myelin regeneration.
