| Research Abstract |
In this study, we examined the roles of autophagy in periodontal tissue. Periodontal ligament (PDL) cells are crucial for balancing the homeostasis, wound healing and tissue regeneration in periodontal tissue. We found that autophagy actively regulated the synthesis of ECM protein and stress response in PDL cells against various environmental stress. We also found that autophagy was defective in aged PDL cells those were exposed to senescence inducing stimulus, such as nutrient starvation, inflammatory cytokines and oxidative stress.
