IL‐6 is a proinflammatory cytokine that induces bone resorption and plays a major role in acute inflammation.28 The chemoattractants IL‐8 and MCP‐1 are of great importance for immunopathogenesis of periodontal disease.29 Furthermore, gene expression levels of TLR2 and TLR4 were measured. Here, CXCL8 is linked to periodontal disorder.
