| The study also showed that boosting HO-1 activity reduces the accumulation of inflammatory T cells on myelin sheaths. In some instances, attempted remyelination was suggested by the formation of a secondary thin myelin sheath around an axon that had abnormal myelin (figure 2, D). Waxman's early research showed that when the axon's protective myelin sheath is damaged, as happens in MS, the exposed parts of the axon don't contain enough sodium channels to power nerve conduction. |
