In contrast, the percentage of late paraplegia was lower in MN-miR-155-KO mice but higher in MN-miR-155-KI mice, indicating that miR-155 deleterious effects in ChAT+ neurons primarily occur during the second day post-ACC in relation with miR-155 intraspinal proinflammatory effects (Figure 1D and Table 1). This evidence concerns the gene CHAT and paraplegia.
