ITGAX and Sepsis: To get further insight into the expansion of CD11chiCD4+ pDCs (that we had previously termed “CD4+ DCs”) in the bone marrow during sepsis, we investigated the expression of CD4 and MHC class II on CD11chi and CD11cint pDCs among total CD11c+Bst2+Ly6C+B220+ pDCs (for gating, see Figure 7A).
