The BDCA-2+ (a novel C-type lectin contributing to the potential suppression of secretion of IFNa/b in pDCs) pDC subpopulation, linked to potential suppression of IFN-α/β secretion, is homogeneously distributed in gastric cancer tissues but is particularly elevated in EBV-positive patients, where it is associated with the diffuse-type of cancer [309,310]. Here, IFNA1 is linked to gastric cancer.
