Organized redistribution and cluster formation of CD11b⁺ cells is dependent on IL-17A production. L. monocytogenes-immune mice were recalled orally with L. monocytogenes and MLN sections at 1 dpr (A) or 2 dpr (B) were imaged. Mice were treated with HRPN (control) or 17F3 (αIL-17A) antibodies. Sections of MLN from L. monocytogenes-immune mice were immunostained for L. monocytogenes (rendered using Spot function of Imaris), GL3 (anti-TCRδ), and CD11b antibodies. Data are representative of two independent experiments, n = 3 mice. (Scale bars, 100 μm.)
