STAT1−/− APCs favor type 17 immune polarization. STAT1−/− APCs favor type 17 immune polarization. WT or STAT1−/− bone marrow dendritic cells were incubated with OTII naive OVA-specific T cells for 5 d in the presence of OVA peptide, with or without preceding challenge with heat-killed MRSA. (A–C) Cytokine levels were determined by Bio-Plex assay (n = 6–8). CNT, control; SA, heat-killed MRSA. *p < 0.05, WT versus STAT1, †p < 0.05, SA versus CNT. Benjamin Lee et al.
