Helicobacter Pylori Ribosomal Protein-A2 Peptide/Silk Fibroin Nanofibrous Composites As Potential Wound Dressing.
Journal of biomedical nanotechnology(2019)
摘要
Although different kinds of antibacterial formulas have been explored against bacterial infections, the development of both biocompatible and efficiently antibacterial matrices is still a challenge. In this study, we report a novel HPRP-A2 antimicrobial peptide/silk fibroin (SF) composite nanofibrous matrix fabricated by an all-aqueous electrospinning process (HPRP-A2 is an antibacterial peptide originated from Helicobacter pylori). The HPRP-A2/SF composite nanofibers had a round and smooth morphology. The incorporation of HPRP-A2 had little influence on both the morphology and biocompatibility of the SF nanofibers. Interestingly, the composite nanofibrous matrices showed an impressive antimicrobial activity against both Gram-positive and Gram-negative bacteria. Furthermore, the HPRP-A2/SF composite nanofibers showed excellent performance on accelerating healing of wound according to the data of animal experiment. Considering the facile and all-aqueous process, the HPRP-A2/SF composite nanofibrous matrices could be a promising candidate for antibacterial or wound management applications.
