In the present investigation, the serum changes of sTWEAK levels, a multifunctional cytokine involved in tissue response to acute injury and inflammation, and of its scavenger receptor sCD163, were monitored for the first time in ultramarathon athletes running the 24-h competition, an extremely demanding race in terms of muscular and physiological exertion. To this aim, venous blood samples were collected from each participant (n = 22, M = 12, F = 10) both before and immediately after the 24-h running. Other than sTWEAK and sCD163, the common serum biomarkers of inflammation (namely CRP and IL-6) and tissue injury (such as CPK, LDH, CPK-MB, troponin-I, and NT-proBNP) were evaluated. All parameters were within the reference ranges at baseline, indicating no alterations of the normal physiological processes before the competition; on the contrary, most biomarkers of tissue damage and inflammation strongly increased after the ultramarathon race. Interestingly, a significant decrement of sTWEAK levels associated with an increment of its scavenger receptor sCD163 was observed at post-race. Positive relationships were evidenced between IL-6 and sCD163 levels and the markers of cardiac damage troponin-I and NT-proBNP. On the contrary, sTWEAK showed an inverse correlation with IL-6 and NT-proBNP. This study opens the way to further investigations aimed at clarifying the role of TWEAK pathway during the prolonged ultraendurance activity, paying particular attention to the link of IL-6, CD163 and TWEAK with the cardiac function.

参加 24 小时比赛的超级马拉松运动员血清 sTWEAK 及其清道夫受体 sCD163 的变化

在本研究中,首次监测了参加 24 小时比赛的超级马拉松运动员的血清 sTWEAK 水平(一种参与组织对急性损伤和炎症反应的多功能细胞因子)及其清道夫受体 sCD163 的变化在肌肉和生理消耗方面要求很高的比赛。为此,在 24 小时跑步之前和之后立即从每位参与者(n = 22,M = 12,F = 10)收集静脉血样本。除 sTWEAK 和 sCD163 外,还评估了炎症(即 CRP 和 IL-6)和组织损伤(如 CPK、LDH、CPK-MB、肌钙蛋白-I 和 NT-proBNP)的常见血清生物标志物。基线时所有参数均在参考范围内,表明比赛前正常生理过程没有改变;相反,在超级马拉松比赛之后,大多数组织损伤和炎症的生物标志物显着增加。有趣的是,在赛后观察到与清道夫受体 sCD163 增加相关的 sTWEAK 水平显着下降。IL-6 和 sCD163 水平与心肌损伤标志物肌钙蛋白-I 和 NT-proBNP 之间存在正相关关系。相反,sTWEAK 与 IL-6 和 NT-proBNP 呈负相关。这项研究为进一步研究开辟了道路,旨在阐明 TWEAK 通路在长时间超耐力活动中的作用,特别关注 IL-6、CD163 和 TWEAK 与心脏功能的联系。在赛后观察到与清道夫受体 sCD163 增加相关的 sTWEAK 水平显着下降。IL-6 和 sCD163 水平与心肌损伤标志物肌钙蛋白-I 和 NT-proBNP 之间存在正相关关系。相反,sTWEAK 与 IL-6 和 NT-proBNP 呈负相关。这项研究为进一步研究开辟了道路,旨在阐明 TWEAK 通路在长时间超耐力活动中的作用,特别关注 IL-6、CD163 和 TWEAK 与心脏功能的联系。在赛后观察到与清道夫受体 sCD163 增加相关的 sTWEAK 水平显着下降。IL-6 和 sCD163 水平与心肌损伤标志物肌钙蛋白-I 和 NT-proBNP 之间存在正相关关系。相反,sTWEAK 与 IL-6 和 NT-proBNP 呈负相关。这项研究为进一步研究开辟了道路,旨在阐明 TWEAK 通路在长时间超耐力活动中的作用,特别关注 IL-6、CD163 和 TWEAK 与心脏功能的联系。
