چکیده انگلیسی
Pepducins constitute a unique class of G-protein coupled receptor (GPCR) modulating lipopeptides. Pepducins with inhibitory effects on neutrophils could potentially be developed into anti-inflammatory pharmaceuticals. A pepducin with a peptide sequence identical to the third intracellular loop of FPR1 was found to inhibit neutrophil functions including granule mobilization and superoxide production. This FPR1-derived pepducin selectively inhibited signaling and cellular responses through FPR2, but not FPR1 as expected. Binding to the neutrophil surface of a conventional FPR2 agonist is also inhibited. The fatty acid is essential for inhibition and pepducins with shorter peptides lose in potency. In summary, a pepducin designed to target FPR1 was found to hijack FPR2 and potently inhibit neutrophil functions.
