1 The antidepressant-like activity of nicotine, but not of 3-furan-2-yl-N-p-tolyl-acrylamide, is regulated by the nicotinic receptor beta4 subunit. Nicotine basic helix-loop-helix family, member e23 Mus musculus
2 Our results indicate that nicotine mediates antidepressant-like activity after acute, subchronic, and chronic treatments in beta4+/+, but not beta4-/-, mice, and that these effects are not mediated by unspecific locomotor stimulation. Nicotine basic helix-loop-helix family, member e23 Mus musculus
3 Nicotine co-administered with PAM-2 produces antidepressant-like activity in both beta4+/+ and beta4-/- mice, except after the acute treatment of beta4-/- mice, and decreases locomotor activity. Nicotine basic helix-loop-helix family, member e23 Mus musculus
4 Nicotine co-administered with PAM-2 produces antidepressant-like activity in both beta4+/+ and beta4-/- mice, except after the acute treatment of beta4-/- mice, and decreases locomotor activity. Nicotine basic helix-loop-helix family, member e23 Mus musculus
5 Nicotine co-administered with PAM-2 produces antidepressant-like activity in both beta4+/+ and beta4-/- mice, except after the acute treatment of beta4-/- mice, and decreases locomotor activity. Nicotine basic helix-loop-helix family, member e23 Mus musculus
6 This suggests that although the beta4 subunit regulates the antidepressant-like activity of nicotine it does not affect the activity elicited by PAM-2 when is co-administered with nicotine. Nicotine basic helix-loop-helix family, member e23 Mus musculus
7 Our findings clearly indicate that beta4-containing nAChRs play an important role in the antidepressant-like activity elicited by nicotine but they are not essential for the modulatory activity of PAM-2. Nicotine basic helix-loop-helix family, member e23 Mus musculus
