Figure 5From: Respiratory allergy to Blomia tropicalis: Immune response in four syngeneic mouse strains and assessment of a low allergen-dose, short-term experimental modelEffect of immunization with 10 ÎĽg per injection ofB. tropicalisextract (Bt E) on the development of experimental respiratory allergy in A/J mice. Control mice were injected with saline (Control). (A) Total cell count in the BALF. (B) Differential cell count in the BALF. (C) Levels of eosinophil peroxidase (EPO) in the BALF. (D) total serum IgE. (E) IgE anti-Bt antibody serum titers as determined by passive cutaneous anaphylaxis (PCA). Each symbol corresponds to the result obtained from an individual animal. (F and G) representative lung sections stained with hematoxylin and eosin of a saline-injected animal (F) and a Bt-sensitized animal (G). The data are representative of three independent experiments. *p < 0.05, **p < 0.01, ***p < 0.001. A-D, Student's t test; E, Mann-Whitney's test. P > 0.05 is not represented.Back to article page
