Figure Lengend Snippet: ( A ) Left, representative flow cytometric analysis of foot skin cells, isolated from C57BL/6 mice and gated for CD11b + SiglecF + eosinophils on the respective days after L. mexicana infection. Right, representative clinical course of C57BL/6 mice infected with L. mexicana and influx of SSC high CD11b + SiglecF + eosinophils as measured by flow cytometry ( n = 4 mice per group, 4 independent experiments). ( B ) Quantification of Il5 mRNA expression by qRT-PCR in L. mexicana -induced skin lesions of C57BL/6 mice (day 0 and day 20: n = 3 mice each; day 6 and day 14: n = 11 mice each; 1–3 independent experiments). ( C ) Bead-based multiplex ELISA of serum cytokines from C57BL/6 mice 14 days p.i. with L. mexicana ( n = 14 mice per group, 3–4 independent experiments). ( D ) Serum IL-5 levels measured by ELISA in C57BL/6 mice infected with L. mexicana (day 0: n = 3; day 6: n = 13; day 14: n = 12; day 20: n = 10; day 56: n = 5, 2–4 independent experiments). ( E ) Right, representative flow cytometric analysis of bone marrow and blood cells isolated from naive or L. mexicana -infected C57BL/6 mice. Left, quantification of the respective population and organ (left panel day 0 n = 5, day 6 n = 9, day 14 n = 11, and day 20 n = 6; middle panel day 0 n = 4, day 6 n = 8, day 14 n = 6, and day 20 n = 6; right panel day 0 n = 5, day 6 n = 10, day 14 n = 12, and day 20 n = 5, 1–3 independent experiments). ( F ) C57BL/6 mice were treated with 500 µg of either isotype control or anti-IL-5 antibody on days 5 and 12 p.i. Right, representative flow cytometric analysis of isolated cells from bone marrow, blood and skin lesions of isotype-treated or anti-IL-5-treated mice. Left, quantification of the respective population and organ (left panel: day 0 n = 5, isotype n = 8, anti-IL-5 n = 8; middle panel: day 0 n = 5, isotype n = 8, anti-IL-5 n = 8; right panel: day 0 n = 3, isotype n = 4, anti-IL-5 n = 4, 2 independent experiments; skin data points were derived from samples pooled from two mice). ( A , E ) Minor differences in gating between the time points reflect that samples were acquired on different experimental days based on the fact that mice were infected with the same parasite batch. Data are mean ± SEM ( A ) or mean ± s.d. ( B – F ). Information regarding the exact p values and the statistical tests performed is provided in the Appendix Table . .
