Abstract:The landscape of migratory conventional dendritic cells (cDCs) comprises XCR1+CD11b- cDC1s, XCR1-CD11b+ cDC2s and intermediate XCR1low/negCD11b- states. cDC1 are unique in their ability to cross-prime lymph node CD8 T cells in a CD4 T cell-dependent manner. In perturbed cancer states cDC1s become particularly scarce in tumors and tumor draining lymph nodes, which decreases T cell infiltration, immunotherapy responses and patient survival. The causes of cDC1 paucity are not fully understood and no specific ther… Show more
