ABSTRACT
Tumor necrosis factor (TNF)-αis a pleiotropic inflammatory cytokine, which is produced chiefly by acti?vated macrophages. Two forms of TNF-α, soluble and transmembrane, can bind tumor necrosis factor receptor (TNFR) 1 or TNFR2, respectively. Recently, a concept has emerged that TNF-α/TNFR pathway plays an important role in the pathogene?sis of multiple sclerosis and remyelination. TNFR1 induces death of oligodendrocytes via death receptor-mediated apoptosis, which leads to demyelination or other neurodegenerative changes. However, TNFR2 has a positive effect on multiple sclero?sis. It facilitates the proliferation and differentiation of oligodendrocyte precursor cells, thus promoting remyelination.
