Figure 1. Endogenous histamine is necessary for IL-4 induced eosinophil recruitment and CCL24 production.

Figure 1

5 μg of IL-4 or BSA, with or without histamine (HA) were administered intratracheally to WT or HDC KO mice for 2 consecutive days and inflammation was determined on day 3. Eosinophils in the BAL fluid were identified using DiffQuick staining of cytospun BAL fluid cells (A). CCL24 levels were measured in BAL fluid by ELISA (B). Data represent mean ± SEM from 3 independent experiments (n = 3-7). *p < 0.05; *** p < 0.005 by Students t-test.
