Key Points

  • The aim is to investigate how Staphylococcal biofilm exoproteins affect nasal epithelial cell healing.
  • Assessment of mucociliary function in the presence of biofilm exoproteins
  • Evaluation of nasal epithelial cell re-epithelialization
  • Measurement of cytotoxicity and inflammation levels
  • Analysis of reactive oxygen species (ROS) release
  • Biofilm exoproteins significantly hindered re-epithelialization of nasal epithelial cells
  • Mucociliary function was reduced due to exoprotein activity
  • Inflammatory responses were elicited alongside cytotoxic effects
  • Reactive oxygen species (ROS) release was concurrently diminished

Abstract

Staphylococcal biofilm exoproteins hindered mucociliary function and re-epithelialization of the nasal epithelium, caused cytotoxicity, elicited inflammation, and concurrently reduced ROS release.
