Activation of NF-κB in Schwann cells is dispensable for myelination in vivo

J Neurosci. 2013 Jun 12;33(24):9932-6. doi: 10.1523/JNEUROSCI.2483-12.2013.

Abstract

Peripheral myelination is a dynamic process orchestrated by axons and Schwann cells. Although the signaling mechanisms governing myelination are not fully understood, NF-κB activation in Schwann cells has been implicated as a key regulator in vitro. Using a mouse model, we show that nuclear factor κB activation in Schwann cells is not required for myelination in vivo.
