TABLE 1 Percentages of IBa modulation by opioid receptor agonists and antagonists in Cav2.3/μ-, δ-, or κ-OR cells and Cav2.2/μ-, δ-, or κ-OR cells
DAMGO (1 μM), SNC80 (1 μM), and Sal-A (1 μM) were used as agonists, whereas naloxone (1 μM), BNTX (100 nM), and GNTI (100 nM) were used as antagonists of µ-, δ-, and κ-ORs, respectively. Inhibition and potentiation data are shown as the mean ± S.E.M. (n, number of experiments, in parentheses). Total modulation (mean) is estimated as the sum of inhibition and potentiation.
