  • 最新研究进展:
    TNFRSF11B,全称为肿瘤坏死因子受体超家族成员11B(tumor necrosis factor receptor superfamily member 11B),是一种重要的肿瘤坏死因子受体。最新的研究表明,TNFRSF11B参与调节多种生理和病理过程,包括骨代谢、炎症、免疫调节、心血管疾病和某些肿瘤的发生等。研究者们正在努力深入研究TNFRSF11B的作用机制,以期为相关疾病的治疗提供新的靶点和策略。
  • 功能:
    Acts as decoy receptor for TNFSF11/RANKL and thereby neutralizes its function in osteoclastogenesis. Inhibits the activation of osteoclasts and promotes osteoclast apoptosis in vitro. Bone homeostasis seems to depend on the local ratio between TNFSF11 and TNFRSF11B. May also play a role in preventing arterial calcification. May act as decoy receptor for TNFSF10/TRAIL and protect against apoptosis. TNFSF10/TRAIL binding blocks the inhibition of osteoclastogenesis.

    24. OPG and OPG/TRAIL ratio expression were significantly increased in rheumatoid arthritis patients compared to controls (fold change = 1.79, p = 0.013 and 2.07, p = 0.030, respectively), RANKL/OPG ratio was significantly decreased (fold change = 0.50, p = 0.020).

This study was conducted in Tunisia. PMID: 27111559
    50. Studies showed that the central hypothalamic-pituitary regulatory system, via it's relative hormones, seems to control OPG/RANKL/RANK system function, and the pulsatility and circadian rhythmicity of these hormones may induce an oscillatory fluctuation of the OPG/ RANKL ratio. Also, psycological characteristics may provoke a shift of the OPG/ RANKL ratio towards an unbalanced or a balanced status. [review] PMID: 27862210
