Fig. 3. Acute administration of NicA2-J1 decreased withdrawal-induced hyperalgesia.

(A) Detailed timeline of the experiments. (B) Mechanical nociceptive thresholds immediately after nicotine escalation and 48 hours into withdrawal. During withdrawal, a significant decrease in hyperalgesia thresholds was observed compared with baseline (BSL) thresholds (n = 11; t = 11.9, df = 10, P < 0.01). (C) In PBS-treated animals, a significant decrease in hyperalgesia thresholds was observed compared with baseline thresholds at 24 hours into withdrawal (n = 11; t = 13.89, df = 10, P < 0.01) and 48 hours into withdrawal (n = 11; t = 9.96, df = 10, P < 0.01) but not during nicotine self-administration. (D) In NicA2-J1–treated rats, a decrease in hyperalgesia thresholds was observed at 24 hours into withdrawal (n = 11; t = 13.89, df = 10, P < 0.05). *P < 0.05, **P < 0.01.
