Abstract

Signaling through the PGI2 receptor (IP) has been shown to inhibit inflammatory responses in mouse models of respiratory syncytial viral infection and OVA-induced allergic responses. However, little is known about the cell types that mediate the anti-inflammatory function of PGI2. In this study, we determined that PGI2 analogs modulate dendritic cell (DC) cytokine production, maturation, and function. We report that PGI 2 analogs (iloprost, cicaprost, treprostinil) differentially modulate the response of murine bone marrow-derived DC (BMDC) to LPS in an IP-dependent manner. The PGI2 analogs decreased BMDC production of proinflammatory cytokines (IL-12, TNF-α, IL-1α, IL-6) and chemokines (MIP-1α, MCP-1) and increased the production of the anti-inflammatory cytokine IL-10 by BMDCs. The modulatory effect was associated with IP-dependent upregulation of intracellular cAMP and down-regulation of NF-κB activity. Iloprost and cicaprost also suppressed LPS-induced expression of CD86, CD40, and MHC class II molecules by BMDCs and inhibited the ability of BMDCs to stimulate Ag-specific CD4 T cell proliferation and production of IL-5 and EL-13. These findings suggest that PGI2 signaling through the IP may exert anti-inflammatory effects by acting on DC.
