Figure 2. B Cell Deficiency Exacerbates Emphysematous Pathology after Nb Inoculation.
(A–E) BALB/c WT and Jh−/− mice were inoculated with 600 L3 and, 7 days later, were analyzed for emphysematous pathology and IL-17 expression.
(A) Left lobe of lung was collected and photographed (scale bar, 5 mm).
(B) H&E staining of representative formalin-fixed lung sections of mice.
(C) Digital imaging analysis of mean linear intercept measurements (Lm) of alveolar spaces.
(D) Number of lung IL-17A+ γδ T cells.
(E) Number of neutrophils (CD11b+Ly6G+), analyzed by FACS.
(F–I) WT and Jh−/− mice were inoculated with 300 L3 and, 30 days later, were analyzed for emphysematous pathology. H&E staining (F) and Lm analyses (G) were assessed as described earlier, and the number of lung IL-17A+ γδ T cells (H) and lung neutrophils (CD11b+Ly6G+) (I) was determined by flow cytometry.
Each symbol represents an individual mouse, and horizontal lines indicate the mean. Data shown are representative of at least two independent experiments (*p < 0.05, **p < 0.01).
