Abstract

Argonaute 2 bound mature microRNA (Ago2-miRNA) complexes are key regulators of the wound inflammatory response and function in the translational processing of target mRNAs. In this study, we identified four wound inflammation-related Ago2-miRNAs (miR-139-5p, miR-142-3p, miR-142-5p, and miR-223) and show that miR-223 is critical for infection control. miR-223 ^Y/− mice exhibited delayed sterile healing with prolonged neutrophil activation and interleukin-6 expression, and markedly improved repair of Staphylococcus aureus-infected wounds. We also showed that the expression of miR-223 was regulated by CCAAT/enhancer binding protein alpha in human neutrophils after exposure to S. aureus peptides. Treatment with miR-223 ^Y/− -derived neutrophils, or miR-223 antisense oligodeoxynucleotides in S. aureus-infected wild-type wounds markedly improved the healing of these otherwise chronic, slow healing wounds. This study reveals how miR-223 regulates the bactericidal capacity of neutrophils at wound sites and indicates that targeting miR-223 might be of therapeutic benefit for infected wounds in the clinic.
