ITGAX and infection: To investigate whether this occurred, we injected CFSE into the FPs of WT and CD1d-KO mice 3 days after s.c. DENV2 infection and tracked CFSE+ and CFSE– monocyte/macrophages (CD11b+CD11c–MHC-II+, gating strategy, Supplemental Figure 4) and conventional DCs (cDCs, CD11c+CD11b–MHC-II+, gating strategy, Supplemental Figure 4) in the dLNs at day 5 after infection by flow cytometry.
