CHAT and paraplegia: Of note, the 24.6% reduction of the percentage of paraplegia obtained by deleting miR-155 only in ChAT+ neurons represents 65.8% of the reduction (37.4%) given by global miR-155 deletion (Awad et al., 2018), suggesting that miR-155 activity in other, non-ChAT+ cells of the SC may add to the deleterious effects of this microRNA after ACC.
