Netrin-1, through its activation of DCC, triggers TRPC channel mediating the Ca+2 influx that is required for the growth cone turning. The effect of netrin-1 on TRP currents in the neurons is studied in Xenopus. In cultured Xenopus spinal neurons, Netrin-1 evoked Ca+2 influx and a depolarizing, TRPC-like current in both soma and growth cones. Inhibition of the Xenopus homologue of mammalian TRPC1 (XTRPC1) prevented Ca+2 influx, TRPC-like current activation and the chemotropic turning of the growth cone in response to a gradient of Netrin-1.
Netrin-1 receptor signalling to TRPC channels is mediated via hydrolysis of PIP2 by PLCgamma which then activates TRPC channel activity through IP3 and DAG.
