CX3CR1+ and CD103+ dendritic cells (DCs) in intestinal lamina propria (LP) play a key role in mucosal immunity. However, the origin and the developmental pathways that regulate their differentiation in the LP remain unclear. Our results reveal that monocytes give rise exclusively to CX3CR1+CD103− LP DCs under the control of M-CSFR and Flt3 ligands. In contrast, common DC progenitors (CDP) and pre-DCs, which give rise to lymphoid organ DCs but not to monocytes, differentiate exclusively into CD103+CX3CR1− LP DCs under the control of Flt3 ligand and GM-CSF. CD103+CX3CR1− DCs but not CX3CR1+CD103− DCs in the LP constitutively express CCR7 and are the first DCs to transport pathogenic Salmonella from the intestinal tract to the mesenteric lymph nodes. Altogether, these results underline the diverse origin of the LP DC network and identify mucosal DCs that arise from pre-DC as key sentinels of the gut immune system.
