概要 Proteinase-activated receptor 2 (PAR-2) and toll-like receptor 4 (TLR4) are involved in innate immune responses and signaling cross-talk between these receptor molecules has the potential to augment an ongoing inflammatory response. The aim of this study was to evaluate the possible cooperative influence of PAR-2 and TLR4 on IL-12p40 production by macrophages after stimulation with lipopolysaccharide (LPS). During culture, GM-CSF upregulated PAR-2 expression by macrophages in a time-dependent manner. Stimulation with LPS enhanced IL-12p40 production by macrophages in a concentration-dependent manner.
