CD4 and infection: Of note, other immune cell populations including CD3+, CD4+, or CD8+ T cells; dendritic cells (DCs, defined as CD11c+MHCII+Ly6C−Ly6G−, CD11c+MHCII+Ly6C−Ly6G−CD8+, or CD11c+MHCII+Ly6C−Ly6G−CD8− cells); or neutrophils (defined as CD11b+CD11c−Ly6G+) did not express DR5 24 h after infection, while monocytes (defined as CD11b+CD11c−Ly6C+Ly6G− cells) upregulated DR5 (Fig EV1E).
