Intracellular signaling pathways that promote axon regeneration are closely linked to the mechanism of neurite outgrowth. TC10, a signaling molecule that acts on neurite outgrowth through membrane transport, is a member of the Rho family G-proteins. Axon injury increases the TC10 levels in motor neurons, suggesting that TC10 may be involved in axon regeneration. In this study, we tried to understand the roles of TC10 in the nervous system using TC10 knock-out mice. In cultured hippocampal neurons, TC10 ablation significantly reduced axon elongation without affecting ordinary polarization...
