Protein kinase D1 (PKD1) is expressed ubiquitously and regulate diverse cellular processes such as oxidative stress, gene expression, cell survival, and vesicle trafficking. However, the presence and function of PKD1 in monocytic cells are currently unknown. Here we provide evidence that PKD1 is involved in Toll-like receptor (TLR) 9 signaling in macrophages. Class B type CpG DNA (CpG-B DNA) induced activation of PKD1 via a pathway that is dependent on endosomal pH, TLR9, MyD88, and IRAK1 in macrophages. Upon CpG-B DNA stimulation, PKD1 interacted with the TLR9/MyD88/IRAK/TRAF6 complex. Knockdown of PKD1 revealed that PKD1 is required for activation of NF-κB and MAPKs, and subsequent expression of cytokines in response to CpG-B DNA. Our findings identify PKD1 as a key signaling modulator in TLR9-mediated macrophage activation.
