Gating is definitely demonstrated and dotted lines represent the median fluorescent intensity of cells from uninfected mice. Data is definitely representative of Tesaglitazar n = 5 mice per group per time points, from 2 self-employed repeats.(PDF) ppat.1006640.s005.pdf (287K) GUID:?2C09AA0A-8193-4B04-A213-5B1DA7629C54 S6 Fig: IL-6 does not regulate myeloid cell numbers after RSV infection. 8 week aged BALB/c mice were infected with 8 x 105 ffu of RSV A2 i.n. and given 0.5 mg of either HRPN (IgG1) or MP5-20F3 (IL-6) i.p. on day time -1 p.i. and 0.25 mg i.p. every other day time after that. (A) Lung cells were incubated with brefeldin A for 6 hrs and the rate of recurrence of IL-6+, IL-27+ and TNF+ lung alveolar macrophages (AF+CD68+CD11c+) was determined by circulation cytometry. (B) The number of alveolar macrophages, neutrophils, monocyte/macrophages, CD11b+ and CD11b- DCs was determined by circulation cytometry.
