Transcriptional analysis of dendritic cells upon TLR stimulation reveals an immunosuppressive profile [Spl scRNA-seq]

Dendritic cells (DCs) simultaneously prime and dampen the immune response. The transcriptional program that regulates immunosuppression in DCs is currently unknown. Here we identified ETS homologous factor as a key transcription factor that regulates DC immunosuppression. Mice were immunized intraperitoneally (i.p.) with or without 60 µg TLR stimulation in 100 µL PBS. Splenic cells were collected 18 hrs after injection for cDCs (live MHCII+ CD11c+) FACS-sorting for scRNA-seq library preparation.
