phycoerythrin, phycoerythrinCy7, peridinin-chlorophyll protein complexes,
allophycocyanin, or allophycocyanin-Cy7 were purchased from BioLegend (San
Diego, CA,). Lamina propria cells in colon were stained with the antibodies
against murine CD45 (30-F11, BioLegend), CD11b (M1/70, BioLegend), CD11c
(N418, BioLegend), CD103 (2E7, BioLegend), Ly6G (1A8, BioLegend), MHC-II
(M5/114.15.2, BioLegend) and F4/80 (BM8, BioLegend) and Zombie Aqua Fixable
viability kit (423101, BioLegend). In flow cytometric analysis, at least
100,000 live samples were analyzed using BD LSRFortessa™X-20 (BD Biosciences) and FlowJo software (Tree Star, OR). The
CD45+ cells were classified into neutrophils
(CD11b+Ly6G+) and dendritic cells
(CD11c+MHC-II+CD103+).
