ITGAX and infection: To characterize the interaction between pDCs (phenotypically defined as viable lineage-HLA-DR+CD11c-CD123+ cells, Figure S1) and rotavirus, pDCs were purified from human blood by negative selection (mean purity ± standard error mean [SEM]: 86.48%±0.92) and exposed to RRV at a multiplicity of infection (moi) of 5 or 10, or to equivalent quantities of inactivated RRV (iRRV).
