摘要:

文题释义:

瘦素:是一种由白色脂肪组织分泌的蛋白质荷尔蒙,编码基因ob,位于人类的第七号染色体上,由167个氨基酸构成,大小为16 kD。瘦素具有广泛的生物学效应,早期研究发现其主要作用于下丘脑的代谢调节中枢,发挥抑制食欲、增加能量消耗、抑制脂肪合成的作用,现研究发现其还具有参与调控炎症反应、免疫稳态、软骨和骨代谢、血管生成、造血(血细胞的形成)、细胞增殖等多个进程。
效应细胞:是指对刺激产生相应反应并发生改变的一类细胞。效应细胞包括成纤维细胞、肥大细胞、浆细胞、效应T细胞、软骨细胞、小胶质细胞等。此文所研究的成纤维细胞,为滑膜组织的支撑细胞,在瘦素的影响下可发生促炎反应;而软骨细胞为人体软骨内唯一的细胞,瘦素可对其促炎、自噬、凋亡、增殖等方面起到调控作用。

背景:瘦素是由脂肪组织合成的一种多效性脂肪因子和肽激素,最初被认为主要发挥食欲调节和能量平衡的作用。深入研究后发现,瘦素还具有参与调控慢性炎症和肌肉骨骼系统疾病的作用。
目的:就瘦素和瘦素受体的概念、目前瘦素对骨关节炎中软骨、软骨下骨和滑膜上主要效应细胞的调控作用等方面进行综述。
方法:结合英文检索词(leptin、Obese Protein、Obese Gene Product、Gene Product, Obese、Ob Gene Product、Gene Product, Ob、Ob Protein、Osteoarthritis、OA、Osteoarthritides、Osteoarthrosis、Osteoarthroses、Arthritis, Degenerative、Arthritides, Degenerative、Degenerative Arthritides、Degenerative Arthritis、Arthrosis、Arthroses、Osteoarthrosis Deformans)和中文检索词(瘦素、LP、Ob蛋白质、肥胖蛋白质、骨关节炎、OA、退行性骨关节炎、骨关节病、变形骨关节炎),检索PubMed、Web of Science、CNKI(中国知网)、cqVIP(维普资讯网)、万方全文数据库,搜索关于瘦素对骨关节炎主要组织中效应细胞的影响相关领域的文章,进行总结和综述。

结果与结论:①瘦素对骨关节中主要组织效应细胞起到调控作用,影响骨关节炎的发生发展。②瘦素对软骨中的细胞外基质主要起到分解作用,对软骨细胞发挥促炎、抑制自噬、诱导衰老、诱导凋亡、双相调节增殖的作用。③瘦素诱导成骨细胞增殖与分化、抑制破骨细胞活性与增殖,影响软骨下骨骨重塑,导致骨赘的形成。④瘦素对滑膜巨噬细胞与成纤维细胞的调控主要在于介导骨关节炎炎症反应。⑤瘦素未来有望成为骨关节炎预后生物标记物及治疗的潜在靶点。

Abstract: BACKGROUND: Leptin is a multipotent adipose factor and peptide hormone synthesized by adipose tissue, which was initially thought to play a major role in appetite regulation and energy balance. In-depth studies have revealed that leptin also plays a role in regulating chronic inflammation and musculoskeletal system diseases.
OBJECTIVE: To review the concepts of leptin and leptin receptor and the regulation of leptin on the main effector cells in cartilage, subchondral bone and synovium in osteoarthritis.
METHODS: By combining English search terms (Leptin, Obese Protein, Obese Gene Product, Gene Product, Obese, Ob Gene Product, Gene Product, Ob, Ob Protein, Osteoarthritis, OA, Osteoarthritides, Osteoarthrosis, Osteoarthroses, Arthritis, Degenerative, Arthritides, Degenerative, Degenerative Arthritides, Degenerative Arthritis, Arthrosis, Arthroses, Osteoarthrosis Deformans) and Chinese search terms (leptin, LP, Ob protein, obesity protein, osteoarthritis, OA, degenerative osteoarthritis, osteoarthropathy, osteoarthritis), PubMed, Web of Science, CNKI, cqVIP, and WanFang full-text database were searched for related articles about the effect of leptin on effector cells in the main tissues of osteoarthritis.
RESULTS AND CONCLUSION: Leptin plays a regulatory role in the main tissue effector cells in bone joints and affects the occurrence and development of osteoarthritis. Leptin mainly decomposes the extracellular matrix in the cartilage, and promotes inflammation, inhibits autophagy, induces aging and apoptosis, and biphasically regulates the proliferation of chondrocytes. Leptin induces the proliferation and differentiation of osteoblasts, inhibits the activity and proliferation of osteoclasts, affects the remodeling of subchondral bone, and leads to the formation of osteophytes. Leptin regulates synovial macrophages and fibroblasts mainly by mediating inflammatory response in osteoarthritis. Leptin is expected to be a prognostic biomarker and a potential target for the treatment of osteoarthritis in the future.
