Abstract

We synthesized and investigated the effect of formyl peptide receptor 2 (FPR2)-derived pepducins in human monocytes. The FPR2-based cell-penetrating lipopeptide, "pepducin" (F2pal-16), stimulated intracellular calcium increase in human monocytes via pertussis toxin (PTX)-sensitive G-protein and phospholipase C (PLC) activity. From a functional aspect, we showed that F2pal-16 stimulated monocyte chemotaxis. F2pal-16 also stimulated the generation of superoxide anion in human monocytes. Moreover, F2pal-16 dramatically increased the production of several kinds of pro-inflammatory cytokines (CXCL8, CCL2, IL-1β and TNF-α) in human monocytes via NF-κB activation. Since FPR2 plays an important role in immune responses, F2pal-16 can serve as a useful reagent for the study of FPR2-mediated immune modulation.
