Task: Answer Verification
Input (English): Question: Is lPS-induced MCP-1 and IL-6 production reversed by oestrogen in human periodontal ligament cells?
Answer: LPS stimulates PDL cell IL-6 and MCP-1 production but has no effect on the normal physiological properties of PDL cells. LPS-induced IL-6 and MCP-1 is not reversed by oestrogen suggesting that oestrogen exerts no anti-inflammatory effect via this mechanism.
Output (English): no
