Overview

Family of small cationic antimicrobial peptides that form first line of innate immune defense.

Mechanism of Action

Disrupt microbial membranes via electrostatic interaction and pore formation, neutralize toxins and viruses, modulate immune cell recruitment (chemotactic), induce cytokine production, promote wound healing.

Key Benefits

  • Broad-spectrum antimicrobial activity
  • Antiviral effects
  • Immunomodulation
  • Wound healing support
  • Anti-biofilm properties
  • Mucosal defense enhancement
