Dendritic cells (DCs), antigen-presenting cells linking innate and adaptive immunity, are required for initiation of specific T cell-driven immune responses. Phosphoinositide-3-kinase (PI3K) suppresses proinflammatory cytokine production in DCs, which limits T helper (Th1) polarization. PI3K is in part effective by downregulation of transcription factor NF-κB. Downstream signaling elements of PI3K include serum- and glucocorticoid-inducible kinase 1 (SGK1) and its phosphorylation target N-myc downstream regulated gene 1 (NDRG1). The present study explored whether SGK1 and NDRG1 play a role in the regulation of NF-κB and DC-maturation.
