The purpose of this study was to investigate the influence of moderate physical activity (MPA) on the expression of osteoarthritis (OA)-related (IL-1β, IL-6, TNF-α, MMP-13) and anti-inflammatory and chondroprotective (IL-4, IL-10, lubricin) biomarkers in the synovium of an OA-induced rat model. A total of 32 rats were divided into four groups: Control rats (Group 1); rats performing MPA (Group 2); anterior cruciate ligament transection (ACLT)-rats with OA (Group 3); and, ACLT-rats performing MPA (Group 4). Analyses were performed using Hematoxylin & Eosin (H & E) staining, histomorphometry and immunohistochemistry. In Group 3, OA biomarkers were significantly increased, whereas, IL-4, IL-10, and lubricin were significantly lower than in the other experimental groups. We hypothesize that MPA might partake in rescuing type B synoviocyte dysfunction at the early stages of OA, delaying the progression of the disease.
本研究旨在探讨适度体力活动(MPA)对骨关节炎(OA)相关(IL-1β、IL-6、TNF-α、MMP-13)和抗炎及软骨保护(IL-4、IL-10、润滑素)生物标志物在 OA 诱导的大鼠模型滑膜中表达的影响。共 32 只大鼠分为四组:对照组大鼠(第 1 组);进行 MPA 的大鼠(第 2 组);前交叉韧带切断(ACLT)-OA 大鼠(第 3 组);以及进行 MPA 的 ACLT 大鼠(第 4 组)。使用苏木精和伊红(H & E)染色、组织形态计量学和免疫组织化学进行分析。在第 3 组中,OA 生物标志物显著增加,而 IL-4、IL-10 和润滑素显著低于其他实验组。我们假设 MPA 可能参与在 OA 早期挽救 B 型滑膜细胞功能障碍,从而延缓疾病的进展。
