Abstract:

Periodontitis is a chronic infectious disease characterized by the destruction of periodontal tissue. The host's immune response is an important cause of attachment loss and alveolar bone resorption. When protein synthesis is overloaded, it is easy to produce unfolded or misfolded proteins which accumulate in the endoplasmic reticulum lumen and cause endoplasmic reticulum stress (ERS). Although the cells can induce an unfolded protein response (UPR) to mitigate ERS through related pathways, ERS inevitably persists in the pathological environment of periodontitis, and the interacting UPR can mediate pro-inflammatory transcriptional procedures and induce apoptosis, leading to the imbalance of bone remodeling and alveolar bone loss. This article reviewed the studies on ERS mediated bone remodeling imbalance in periodontitis and its potential therapeutic targets in order to further understand the role and significance of ERS in bone metabolism and treatment of periodontitis.

Key words: Periodontitis, Endoplasmic reticulum stress, Unfolded protein response, Apoptosis, Alveolar bone loss
