Formalin and capsaicin responses of C fibers in TRPA1 wild type and knockout mice. A) Percentage of total C fibers responding to formalin in Trpa1 +/+ or -/- mice (p = 0.046; Fisher's exact test). B) The average formalin-evoked action potentials over 2 min in C fibers from Trpa1 +/+ or -/- mice. C) Percentage of total C fibers responding to capsaicin in Trpa1 +/+ or -/- mice (p > 0.05; Fisher's exact test). D) The average capsaicin-evoked action potentials over 2 min in C fibers from Trpa1 +/+ or -/- mice.
