Relative expression of transcripts encoding eosinophil proteins. Relative expression of (A) mouse eosinophil peroxidase (mEPO), (B) mouse eosinophil major basic protein (mMBP), (C) mouse plasminogen activator inhibitor-2 (mPAI-2), and (D) mouse interleukin-5 receptor alpha (mIL-5Rα) from bone marrow RNA of uninfected and S mansoni–infected wild-type BALB/c and eosinophil lineage–ablated ΔdblGATA mice at t = 8 weeks after exposure to cercariae. Values are mean fold change ± SEM with the expression in BALB/c uninfected mice normalized to 1.0; n = 4 mice per group; *P < .01 vs all other data points shown.
