Staphylococcus aureus–Derived PSMα Peptides Activate Neutrophil FPR2 but Lack the Ability to Mediate β-Arrestin Recruitment and Chemotaxis
Abstract
Formyl peptide receptor 2 (FPR2) is a G protein–coupled pattern recognition receptor sensing both mitochondrial- and bacterial-derived formylated peptides, including the PSMα toxins secreted by community-associated methicillin-resistant Staphylococcus aureus strains. Similar to many other FPR2 agonistic peptides, nanomolar concentrations of both PSMα2 and PSMα3 activate neutrophils to increase the cytosolic concentration of Ca2+ and release...
