We investigated whether capsaicin induces itching in skin with existing inflammation. We induced skin inflammation by intradermal injection of complete Freund’s adjuvant (CFA) in the neck of mice. Four days later, we injected capsaicin in the same area and counted the number of scratching bouts for 30 min. We examined potential effects on pain in parallel experiments in which CFA and capsaicin were intradermally injected into hind paws. We used the time spent licking the hind paws during the 15 min after capsaicin injection as an estimate of pain. Capsaicin injection into the skin pretreated with CFA, but not into healthy skin, induced scratching. The scratching behavior was reduced by pretreatment with naloxone or capsazepine, selective antagonists for transient receptor potential vanilloid receptor-1 (TRPV1), but not morphine or mepyramine, selective antagonists for histamine 1 receptor. In animals injected with capsaicin into the hind paws, licking behavior was significantly inhibited via a µ-receptor-dependent mechanism. Our results show that TRPV1 activation, which normally induces pain, evokes an itch-related response in the presence of inflammation. This model may be interesting for future studies to explore the mechanism of a painful stimuli-induced itch observed under pathological conditions.
