研究目的: |
老年性骨质疏松(SOP)是一种常见的疾病,肠道菌群失调与老年性骨质疏松的发生发展具有一定关联,但调控SOP的具体肠道菌株以及相关机制报道甚少。本课题组发现SOP患者粪便中普雷沃氏菌(P. Copri)呈优势生长,而SAMP6(快速衰老小鼠P6品系)小鼠在进行老年性骨质疏松患者粪菌移植后发现其骨质疏松程度加重,同时血清骨代谢标志物较移植前显著差异。基于此发现拟:1.研究P.Copri对SAMP6小鼠骨质疏松症和全身低度炎症的调控作用。2.研究P. Copri改变肠道内代谢产物对诱导破骨细胞的形成分化具有调控作用,应用粪菌移植技术明确P.Copri是否通过诱导破骨细胞加重SOP。3.通过体内体外上调SCFA(短链脂肪酸)的表达,阐明SCFA的减少是由于P.Copri的优势生长破坏肠道屏障功能,HAL(羟基柠檬酸内酯)易于进入体内,加速SOP的发生发展。本课题拟为SOP的防治提供新思路。 |

Objectives of Study: |
Senile osteoporosis (SOP) is a common disease. The imbalance of intestinal flora is related to the occurrence and development of osteoporosis in the elderly.However, there are few reports on specific intestinal strains and related mechanisms regulating SOP. Our team find that Prevotella Copri (P.Copri) in the stool of patients with SOP shows dominant growth, while in SAMP6 mice the degree of osteoporosis increases after fecal bacteria transplantation with the stool from SOP patients, and the serum bone metabolism markers are significantly different from those before transplantation. Based on this finding, the project plans to: 1.Study the regulatory effect of P.Copri on osteoporosis and systemic low-grade inflammation in SAMP6 mice. 2. Study the regulatory effect of P. Copri on the formation and differentiation of osteoclasts by changing the metabolites in the intestine, and to determine whether P.Copri aggravates SOP by inducing osteoclasts. 3. By up regulating the expression of SCFA in vivo and in vitro, it is clarified that the decrease of SCFA is due to the damage of intestinal barrier function by the dominant growth of P.Copri. HAL is easy to enter the body, which accelerates the development of SOP . This project aims to provides new ideas for the treatment of SOP |
