Histologic analysis of eosinophils in Peyer's patches of wild-type and IL-5–transgenic mice.
Eosinophils were evaluated in the Peyer's patches of wild-type (A), IL-5–transgenic (B), and IL-5–transgenic eotaxin-deficient (C) mice. Eosinophils were identified by anti-MBP immunostaining. In (A), eosinophils are indicated with arrowheads. The original magnification is × 106.
