摘 要:One of the leading issues in multiple sclerosis(MS)research is the lack of understanding regarding the triggers of *** demyelination is a major feature in MS,the degeneration of gray matter neurons contributes to major changes in patient function,but the mechanisms driving this neuronal loss are *** exciting research published by Luoqian et al.[1]in the December issue of Cellular and Molecular Immunology,new insights have shown an important contribution of ferroptosis to T-cell-mediated neurodegeneration in the common animal model of MS,‘experimental autoimmune encephalomyelitis’(EAE).Although a relationship between ferroptosis and T-cell activation has been reported in other disorders,this is the first discovery of a link between abnormal iron homeostasis and T-cell infiltration in *** addition,the authors found that unlike other studies on ferroptosis-T-cell interactions[2,3],ferroptotic activation of T cells in EAE,and potentially MS,involved the infiltration and activation of CD4+T cells,rather than CD8+***,in this study,ferroptosis was a key driver of T-cell activation rather than the opposite interaction where CD8+cells drive ferroptosis[3].The research also mapped a key role for Acsl4 in the early stages of ferroptosis-T-cell-mediated ***4 converts free long-chain fatty acids into fatty acyl-CoA esters and has been identified as a central contributor to ferroptotic processes[4].This study has mapped a major new pathway potentially leading to neurodegeneration in MS,and this opens the possibility of new therapeutic approaches to treat MS based on iron targeting as the authors describe in their final experiments.
