The Effect of Immobilization Methods of P9-4 Antimicrobial Peptide Onto Gelatin Methacrylate on Multidrug-Resistant Bacteria: A Comparative Study.

Wound dressings play a crucial role in wound management by providing a protective barrier and creating an optimal environment for healing. Photocrosslinkable hydrogels, such as gelatin methacrylate (GelMA), have gained attention for their unique properties but often lack antimicrobial activity. To enhance their effectiveness, researchers are exploring methods to incorporate antimicrobial agents into photocrosslinkable hydrogel dressings.

Upregulation of CD14 in mesenchymal stromal cells accelerates lipopolysaccharide-induced response and enhances antibacterial properties.

Mesenchymal stromal cells (MSCs) have broad-ranging therapeutic properties, including the ability to inhibit bacterial growth and resolve infection. However, the genetic mechanisms regulating these antibacterial properties in MSCs are largely unknown. Here, we utilized a systems-based approach to compare MSCs from different genetic backgrounds that displayed differences in antibacterial activity.
