Splenic T cell responses after intragastric sensitization. C3H/HeOuJ mice were intragastrically exposed to PBS (control), PE, or Ara h 1, 2, 3, or 6 and CT during a 4 week period, as described in material and methods. Spleens were isolated and stimulated with medium alone or PE, or Ara h 1, 2, 3, or 6. Graphs depict levels of IL-5 and IL-13 after stimulation. Data are represented as mean ± SEM of 8 mice. *: p < 0.05 compared to control.
