    Micelle-based delivery systems enhance targeted immune responses by encapsulating TLR7/8 agonist 3M-052, minimizing systemic side effects.

  • 2

    3M-052-loaded micelles induce a localized type I interferon response in zebrafish larvae, promoting antiviral immunity without broad immune activation.

  • 3

    Micelles facilitate the recruitment of neutrophils and macrophages at the injection site, indicating effective immune activation.

  • 4

    Zebrafish larvae infected with Sindbis Virus show reduced viral replication near the site of 3M-052-micelle injection.
