T. spiralis- infected BALB/c mice recruit MC and Ba to mesenteric LN and expand spleen and BM lineage pools. A. Dot plots of BM, spleen, and LN cells from naïve and d12 infected BALB/c mice show the IgE+KIT+ MC lineage populations (square gate). Dot plots are representative of data from 4 experiments. B. Frequencies of MC lineage populations from naïve, d6 and d12 post-infection mice are shown as a percent of total cells isolated from BM, spleen, and LN. C. Frequencies of Ba lineage populations (IgE+CD49b+) in the BM, spleen, and LN as in panel B. Data in panels B and C represent means ± SEM, n = 13 mice per group, 4 experiments. * p<0.05, ** p<0.001, ***p<0.0001.
