Periodontitis is characterized by SCFA metabolic imbalance and a shift in MCs toward a pro-inflammatory M1 state. The upregulation of SCFA receptors and the NF-κB/HIF-1 axis in M1 macrophages suggests an "SCFA receptor-metabolic sensing-inflammatory transcription" mechanism drives disease progression, providing a rationale for therapeutic strategies targeting this pathway.
