| Purpose: | As XCR1+ cDC1 excelled in the secretion of inflammatory cytokines, we were interested whether XCR1+ cDC1 are superior in the activation of NK cells. Therefore, XCR1- and XCR1+ cDC1 were co-cultured with autologous NK cells in presence or not of a TLR ligand cocktail consisting of pIC, R848 and CpG. In some experiments, secreted IL-12 was neutralized by an anti-IL-12p40 antibody. For details, see attached Excel sheet. | ||||
| Conclusion: | XCR1+ cDC1 are superior in the activation of NK cells. This is partly explained by the higher secretion of IL-12. | ||||

| Funding: | This work was partly supported by grants from the German Research Foundation [Deutsche Forschungsgemeinschaft (DFG)] to Diana Dudziak (CRC1181-TPA7, DU548/5-1) and a proposal funded by the Agence Nationale de la Recherche (ANR) and the DFG (DU548/6-1). Diana Dudziak received support from Interdisziplinäres Zentrum für Klinische Forschung (IZKF) (IZKF-A80). Lukas Heger was supported by Erlanger Leistungsbezogene Anschubfinanzierung und Nachwuchsförderung (ELAN) (DE-17-09-15-1-Heger). Diana Dudziak was funded by the Bavarian State of Ministry of Science and Art, Bayresq.Net. | ||||
| Quality control: | As control, NK cells were cultured with or without the TLR ligand cocktail alone without addition of DCs. Further, isotype controls were used to calculate Delta-MFI values. | ||||
