From: Immune response to allergens in sheep sensitized to house dust mite
Eosinophil and mast cell counts in skin of control and HDM-sensitized sheep following intradermal challenge with HDM allergens. Eosinophils and tryptase-positive mast cells were counted in paraffin sections of skin collected from control (n = 4, open bars) and HDM sensitized (n = 5, closed bars) sheep at 6 h and 48 h following cutaneous challenge with saline (SA), house dust mite extract (HDM) or the allergens Der p 1 (Dp 1) and Der p 2 (Dp 2). Cells were counted in the upper and lower regions of the dermis and results expressed as the mean counts ± s.d.; #indicates a significant difference (p < 0.05) in cell counts compared to SA challenge; * indicates significance (p < 0.05) comparing sensitized and control tissues.
