Figure 6. Immunization enhances IFN-γ responses.
(A) At day 22 p.i. the pleural lavage was analyzed for IL-5 and IFN-γ. Combined data of three independent experiments with five mice each group are shown. (B, C) At day 22 p.i. cells from the site of infection were restimulated for 72 h with 5 µg/ml Concanavalin A (ConA), 100 µg/ml complete adult (Ls) or microfilarial (Mf) crude extract of L. sigmodontis and IFN-γ (B) and IL-5 (C) secretion were measured (mean ± SEM). Representative data of two independent experiments with five mice each group. Analysis was done using the 2-way ANOVA, for significances see text.
