Nogo-66 plays a central role in the myelinmediated.inhibition of neurite outgrowth. Tau is a microtubule-.associated protein involved in microtubule assembly.and stabilization. It remains unverified whether tau interacts.directly with growth factor receptors, or engages in.cross-talk with regeneration inhibitors like Nogo-66. Here,.we report that plasmid overexpression of tau significantly.elevated the protein levels of total tau, phosphorylated tau,.and microtubule-affinity regulating kinase (MARK). Nogo-.66 transiently elevated the total tau protein level and persistently.reduced the level of p-S262 tau (tau phosphorylated.at serine 262), whereas it had little influence on the.level of p-T205 tau (tau phosphorylated at threonine 205)..Nogo-66 significantly decreased the protein level of.MARK. Hymenialdisine, an inhibitor of MARK, significantly.reduced the level of p-S262 tau. Overexpression of.tau rescued the Nogo-66-induced inhibition of neurite.outgrowth in neuroblastoma 2a (N2a) cells and primary.cortical neurons. However, concomitant inhibition of MARK abolished the rescue of neurite outgrowth by tau in.N2a cells. We conclude that dephosphorylation of tau at.S262 is able to regulate Nogo-66 signaling, and that.overexpression of tau can rescue the Nogo-66-induced.inhibition of neurite outgrowth in vitro.
