Availability of nutrients, especially leucine and arginine, regulates the mammalian target of rapamycin (mTOR) pathway that controls cell growth. We show that NMDA receptor activation markedly reduces arginine transport by decreasing surface expression of the cationic amino acid transporters (CAT) 1 and 3. Depletion of CAT1 and CAT3 by RNA interference blocks influences of NMDA receptor activation on the mTOR pathway and neuronal process formation. Thus, the CATs mediate influences of NMDA receptor activation on the mTOR pathway that regulates neuronal processes.}, issn = {0270-6474}, URL = {https://www.jneurosci.org/content/27/3/449}, eprint = {https://www.jneurosci.org/content/27/3/449.full.pdf}, journal = {Journal of Neuroscience} }
