Cell adhesion between oligodendrocytes and neuronal axons is a critical step for myelination that enables the rapid propagation of action potential in the central nervous system. Here, we show that the transmembrane protein teneurin-4 plays a role in the cell adhesion required for the differentiation of oligodendrocytes. We found that teneurin-4 formed molecular complexes with all of the four teneurin family members and promoted cell-cell adhesion. Oligodendrocyte lineage cells attached to the recombinant extracellular domain of all the teneurins and formed well-branched cell processes. In an axon-mimicking nanofibers assay, nanofibers coated with the recombinant teneurin-4 extracellular domain increased the differentiation of oligodendrocytes. Our results show that teneurin-4 binds to all teneurins through their extracellular domain, which facilitates the oligodendrocyte-axon adhesion, and promotes oligodendrocyte differentiation via its homophilic interaction.
