Multifunctional Injectable Bioadhesive with Toll-like Receptor 4 and Myeloid Differentiation Factor 2 Antagonistic Anti-inflammatory Potential for Periodontal Regeneration.

ABSTRACT: Effectively addressing inflammation in periodontitis is challenging as conventional injectable hydrogels typically require the addition of drugs to provide sufficient anti-inflammatory effects. To overcome this limitation, we developed a multifunctional injectable hydrogel with inherent properties that antagonize the Toll-like receptor 4 and myeloid differentiation factor 2 complex (TLR4-MD2). This hydrogel allows for direct inhibition of inflammatory pathways without the need for additional drugs. We identified xylitol, caffeic acid, and citric acid as natural materials that effectively meet biological needs for anti-inflammatory and antibacterial effects as well as support bone regeneration. With this in mind, we developed a caffeic-acid-modified poly(xylitol succinate) (PXS)-based iCPC@
