    Alomone Labs snx 482
    Glutamatergic transmission in the NL is predominantly triggered by Ca 2+ entry through N-type VGCCs. A : Both the ipsilateral (open circles) and the contralateral (filled circles) EPSCs recorded from the same NL neuron were largely and irreversibly blocked by the N-type blocker ω-Conotoxin-GVIA (ω-CTx-GVIA, 2.5 μM), with nearly identical time courses. Averaged traces under control (thin traces) and drug (thick traces) conditions are shown on the right. Stimulus artifacts are truncated for clarity. B-C : No inhibition of EPSCs was produced by the P/Q-type blocker ω-Agatoxin-IVA (ω-Aga-IVA, 0.1 μM) or the L-type blocker nimodipine (10 μM). D: A small and reversible inhibition of the EPSCs by the R-type blocker <t>SNX-482</t> (50 nM) was observed. The different time courses of the EPSCs observed in the sampled neurons may be due to different locations of the neurons along the tonotopic frequency axis. E : Summary of the effects of different VGCC blockers on EPSCs of NL neurons. ω-CTx-GVIA inhibited the ipsilateral and the contralateral EPSCs by 88% and 86%, respectively. Blockers for P/Q- and L-type VGCCs had no effects on EPSCs. SNX-482 produced a small inhibition with a large variation among cells. No differences in the percent inhibition by either drug were detected between the ipsilateral and the contralateral EPSCs. Error bars represent standard deviations. n.s.: non-significant (paired t-test, p > 0.05; the number of cells is indicated in parentheses).

    SNX-482 inhibition of non-L-type I Ca in cultured midbrain DA neurons. A. Representative traces illustrating the inhibition of non-L-type I Ca by 100 nM SNX-482 (red). Cells were initially perfused with a bath solution containing 3 μM isradipine (ISR, black). Full block was obtained using 2 μM Cd 2+ (blue). Square pulses (50 ms) were applied to 0 mV from a holding potential of −70 mV (top) B. Current amplitude values plotted as a function of time. After stabilization of I Ca with ISR (black circles), 100 nM SNX-482 was applied. The remaining currents was blocked by 2 μM Cd 2+ . C. SNX-482 inhibition expressed as % of control I Ca after LTCC block using 3 μM ISR. D. Mean current amplitude at the end of ISR application and at the end of SNX-482 application. Data represent the means ± SEM for the indicated number of experiments (N=4). Statistical significance was determined using paired Student’s t-test: *** p
