    Synthetic antimicrobial peptides (AMPs) suppress pro-inflammatory cytokine production while enhancing anti-inflammatory responses in macrophages.

  • 2

    The designed AMPs mitigate the impact of LPS-induced inflammation and influence key molecular pathways favoring M2 polarization.

  • 3

    AMPs exhibit properties such as low cytotoxicity and structural adaptability, making them suitable for next-generation immune-active biomaterials.

  • 4

    These peptides can alleviate inflammatory conditions and promote reparative macrophage phenotypes, acting as dual-function agents.

  • 5

    The study highlights a new design framework for bioinspired, immunomodulatory peptide materials with potential applications in infection control.
