Application of a modified multifunctional short peptide in the treatment of periodontitis.

ABSTRACT: Periodontitis is a chronic inflammatory disease involving plaque biofilm as a pathogenic factor. Potassium ion plays an important role in cellular homeostasis; a large outflow of potassium may lead to local inflammation progression. In this work, the multifunctional short peptide molecule BmKTX-33 was designed by modifying the BmKTX, a Kv1.3 potassium channel inhibitor. This was to explore its antibacterial properties, capability of maintaining cell ion homeostasis, and bone-forming capacity. The results showed that BmKTX-33 had inhibitory effects on S. gordonii, F. nucleatum, and P. gingivalis. Moreover, BmKTX-33 also inhibited excessive potassium outflow in inflammatory environments. Finally, BmKTX-33 promoted MC3T3-E1 early osteogenesis while suppressing the NLRP3 inflammasome's product
