Dose-dependent inhibition of DTH. DbpA-immunized mice were treated with various doses of Map19 (1–500 μg) or Ace19 (500 μg), as described previously. On day 7, mice were challenged with DbpA, and the footpads measured 0 and 24 hours after challenge. Significant values are indicated by an asterisk (P < 0.05; Student t test). Data are expressed as the mean ± SE of five mice.
