Classical dendritic cells (DCs) are key players at the interface between innate and adaptive immunity. In the kidney exist 2 major subsets of cDCs: CD11b+ cDCs and CD103+ cDCs. We investigated their function in the most widely used model of experimental glomerulonephritis (GN) in mice: nephrotoxic nephritis (NTN). Consistent with a role for cDCs in nephrotoxic nephritis, depletion of ZBTB46+ cells (all cDCs) attenuated kidney injury, while deficiency of the CD103+ subset of cDCs accelerated injury via a mechanism that involved increased neutrophils. This RNAseq was performed to analyze transcriptional changes in FACS-sorted renal CD11b+ and CD103+ cDCs under healthy conditions and at day 7 of NTN to reveal why both subsets have different functions in GN.
