YAP and TAZ control peripheral myelination and the expression of laminin receptors in Schwann cells.

ABSTRACT: Myelination is essential for nervous system function. Schwann cells interact with neurons and the basal lamina to myelinate axons using known receptors, signals and transcription factors. In contrast, the transcriptional control of axonal sorting and the role of mechanotransduction in myelination are largely unknown. Yap and Taz are effectors of the Hippo pathway that integrate chemical and mechanical signals in cells. We describe a previously unknown role for the Hippo pathway in myelination. Using conditional mutagenesis in mice, we show that Taz is required in Schwann cells for radial sorting and myelination and that Yap is redundant with Taz. Yap and Taz are activated in Schwann cells by mechanical stimuli and regulate Schwann cell proliferation and transcription of basal lamina recept
