Expression of proteins targeted by NAC or involved in mechanisms of nociceptive sensitization in the dorsal region of the ipsilateral lumbar spinal cord or in the plantar paw of CFA-injected mice receiving repeated administrations of NAC. Mice were treated i.p. with either saline or NAC for seven days (100 mg/kg) once a day, starting from seven days following CFA injection in the plantar paw. Densitometric values are means ± S.E.M. of 3–5 mice. *p < 0.05 (Student’s t-test). NAC: N-acetylcysteine.
