Interestingly, blocking Man/Glc, αGalNAc, GlcNAc or NeuAc residues (using soluble PSA, HPA, WGA or MAA respectively) on “negative” tumor cells before co-culture with “mix DCs” further decreased frequencies of IFNλ1+ cDC1s upon PolyI:C stimulation (Figure 6C), further confirming the positive impact of Man/Glc, αGalNAc, GlcNAc and NeuAc motifs on cDC1s previously suspected. This evidence concerns the gene IFNL1 and neoplasm.
