It is well-established that CD8<sup>+</sup> dendritic cells (DCs) and their migratory counterparts in the periphery comprise the cross-presenting cDC1 subset. In contrast, CD8<sup>neg</sup> DCs are grouped together in the heterogeneous cDC2 subset. CD8<sup>neg</sup> DCs are relatively poor cross-presenters and drive more prominent CD4<sup>+</sup> T cell responses against exogenous antigens. The discovery of the X-C motif chemokine receptor 1 (XCR1) as a specific marker of cross-presenting DCs, has led to the identification of a divergent subset of CD8<sup>+</sup> DCs that lacks the ability to cross-present. Here, we report that these poorly characterized CD8<sup>+</sup>XCR1<sup>neg</sup> DCs have a gene expression profile that is consistent with both plasmacytoid DCs (pDCs) and cDC2. Our data demonstrate that CD8<sup>+</sup>XCR1<sup>neg</sup> DCs possess a unique pattern of endocytic receptors and a restricted toll-like receptor (TLR) profile that is particularly enriched for TLR5, giving them a unique position within the DC immunosurveillance network.</p> dendritic cells;TLR5;XCR1;immunosurveillance;transcriptomics;microarray 2019-01-16
