Next-generation antimicrobial dermal matrix eradicates polymicrobial biofilms and modulates inflammation in in vitro and ex vivo wound models

Reports on peptide-coated dermal substitutes evaluated for anti-biofilm activity and inflammatory modulation across in vitro and ex vivo wound models.

Key Takeaways
  • Dual coating of Nisin and LL-37 onto the BTM dermal matrix eradicated mature polymicrobial biofilms
  • BTM-AMPs reduced metabolically active bacteria by more than fifty percent within six hours ex vivo
  • BTM-AMPs also dampened inflammation by lowering TNF-α levels and enhancing macrophage phagocytosis in vitro
