概括

自发性骨质结晶发生在早期膝关节骨关节炎 (OA) 中. 这项研究发现,与女性相比,男性的成熟骨质细胞形成和MMP7 / MMP9分泌量显著更高,这表明OA进展的潜在基于性别的生物标志物.

科学领域:

骨关节炎的研究研究.
骨生物学骨生物学
免疫学免疫学免疫学

背景情况:

骨质细胞生成,即从外周血液单核细胞 (PBMC) 中形成骨质吸收骨质细胞 (OCs),与骨关节炎 (OA) 病理生理学有关.
调查自发骨质结晶发生 (没有外部刺激的OC形成) 可能会揭示OA的外围生物标志物.

研究的目的:

为了研究男性和女性膝关节OA患者的自发骨质结晶发生.
评估自发骨质细胞形成是否可以作为OA的外围生物标志物.

主要方法:

从40名膝关节OA患者 (20名男性,20名女性;KL等级I-II) 中分离的PBMCs.
在21天内培养的PBMC没有骨质结晶因子.
评估了OC活力,成熟的OC百分比 (TRAP染色),以及Cathepsin K (CTSK),MMP7和MMP9 (ELISA) 的分泌.

主要成果:

性别之间的OC活力没有显著差异.
男人显示显著更高的成熟OC百分比 (p < 0.001).
男性的MMP7和MMP9水平显著更高 (p<0.001),但与女性相比,CTSK水平相似.

结论:

这项研究提供了在早期OA患者中自发骨质结晶发生的第一个证据.
在OC成熟和蛋白质分泌中观察到与性别相关的显著差异.
自发骨质结晶发生可能表明系统性骨再吸收失调,并作为OA生物标志物.

Osteoclasts in Bone Remodeling

Osteoclasts in Bone Remodeling

Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

Bone Disorders

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
