Abstract/OtherAbstract:
Grafted macromolecules often induce granuloma formation with foreign body giant cell (FBGC) infiltration, and this is the main reason for graft failure. Diacylglycerol kinase (DAGK) is an important intracellular mediator of FBGC formation in macrophages. In this study, 4-hexylresorcinol (4HR) inhibited DAGKδ in a macrophage cell line (RAW264.7 cells). As a result of DAGK-δ inhibition by 4HR, FBGC formation was significantly inhibited in RAW264.7 cells. Silk fibroin is a well-known natural macromolecule, and when it is grafted into bone defects, it results in granuloma formation with massive FBGC formation. 4HR-incorporating silk graft materials displayed significant reduction of granuloma formation and increases in the extent of new bone formation in a rabbit calvarial defect model. In conclusion, 4HR could inhibit foreign body reaction via a DAGK-mediated pathway.
