Zeb2 is essential for Schwann cell differentiation, myelination and nerve repair

By studying a severe neuropathy in mice, Quintes, Brinkmann et al. demonstrate that the nuclear zinc-finger protein Zeb2 (Sip1) is essential for Schwann cell differentiation and myelin synthesis. Since Zeb2-deficient Schwann cells continuously express repressors of lineage progression, ‘inhibiting the inhibitors’ emerges as a new principle of peripheral myelination control.
