Gene expression in the ankles of WT and IL-17RA−/− mice.

RNA expression in the ankles of wild-type and Il17ra−/− mice after serum-transfer. WT and Il17ra−/− mice were injected with K/BxN serum. On day 12, total RNA was harvested from whole ankle lysates and RNA levels assessed by qPCR. Data were normalized to the number of β2 microglobulin mRNA copies. Results are presented as the 100-fold of the mean of mRNA copies/β2 microglobulin mRNA copies ± SEM (n = 13 mice per group). Data are compiled from three independent experiments. Differences were evaluated by unpaired two-tailed Student's t test; p
