中文摘要: 课题组前期研究发现编码B细胞活化因子受体(BAFF-R)的肿瘤坏死因子受体超家族13C(TNFRSF13C)基因内含子中含有长链非编码RNA:lncRNA-TNFRSF13C,在侵袭性牙周炎牙龈中表达明显升高,而且可能的相关因子发生变化,推测lncRNA-TNFRSF13C参与侵袭性牙周炎的疾病过程。本研究旨在通过检测健康人、慢性牙周炎和侵袭性牙周炎患者lncRNA-TNFRSF13C与牙龈中BAFF、BAFF-R、龈沟液BAFF水平以及牙周临床指标的相关性;在B细胞中高表达lncRNA-TNFRSF13C,检测其对BAFF、BAFF-R的作用,以及对B细胞功能的影响,探索lncRNA-TNFRSF13C在侵袭性牙周炎的作用和可能的调控机制,为其治疗提供新思路。

英文摘要: According to our previous study, we found that there is long non-coding RNA (lncRNA)-TNFRSF13C in the intron of tumor necrosis factor receptor superfamily 13C (TNFRSF13C) which codes B cell activating factor receptor (BAFF-R). LncRNA-TNFRSF13C significantly increased in gingival tissue in aggressive periodontitis (AgP) and some possible related-factors changed. Thus, we infer that lncRNA-TNFRSF13C is involved in the process of AgP. This research aims to measure BAFF, BAFF-R expression in gingival tissue, BAFF levels in gingival crevicular fluid (GCF) in healthy volunteers, chronic periodontitis or AgP patients and analyze the relationship among lncRNA-TNFRSF13C, these factors and periodontal clinic index, to observe the effect of overexpression of lncRNA-TNFRSF13C on BAFF and BAFF-R levels, and the function of B cell in vitro, to explore the function and possible regulatory mechanism of lncRNA-TNFRSF13C in AgP, which provide a novel idea for the treatment of AgP.
