These observations suggest that CaMKv blocks RhoA activity by preventing its interaction with Lfc. These results demonstrate that CaMKv regulates spine maintenance through RhoA inhibition. The suppression of the Lfc/RhoA pathway by AMPA receptors is implicated in dendritic spine maintenance10. Given that CaMKv expression is upregulated by synaptic activity, CaMKv may be a key signalling protein that transduces the signals from AMPA receptors to suppress RhoA during activity-dependent spine maintenance. Corroborating this, the AMPA receptor blocker NBQX attenuated CaMKv expression in neurons (Fig. 3i,j). Importantly, CaMKv overexpression completely rescued NBQX-induced spine loss (Fig. 3k,l). These findings collectively reveal that activity-dependent CaMKv expression and the subsequent inhibition of Lfc/RhoA are required to mediate AMPA receptor function in spine maintenance.
