摘要

运动在创伤性脑损伤(traumatic brain injury, TBI)后的神经保护作用机制仍有待揭示。目前也缺乏针对TBI的有效治疗手段。本研究旨在考察自主运动和注射益赛普(Yisaipu,TNFR-IgG融合蛋白,TNF抑制剂)联用方式对TBI模型小鼠的影响。雄性C57BL/6J小鼠被随机分为对照组和自主运动组,然后观察6周预防性预自主运动(prophylactic preconditioning exercise, PE)和/或TBI 后注射Yisaipu 对中度TBI小鼠的影响。 结果显示,与单一干预措施比较,PE和Yisaipu的联合干预能更有效减少TBI小鼠的感觉运动和步态功能障碍。同时,这些功能改善伴随着外周血清TNF-α水平下降、系统性炎症减轻、脑内自噬流途径增强和皮层损伤灶体积缩小。鉴于上述神经保护作用,诸如运动和TNF抑制剂联用方式可能是促进TBI患者功能恢复的有效策略,值得进一步研究。

Abstract

The mechanisms underlying exercise-induced neuroprotective effects after traumatic brain injury (TBI) remained elusive, and there is a lack of effective treatments for TBI. In this study, we investigated the effects of an integrative approach of exercise and Yisaipu (TNFR-IgG fusion protein, TNF inhibitor) in a mouse TBI model. Male C57BL/6J mice were randomly assigned to a sedentary group or a group that followed a voluntary exercise regimen. The effects of 6-week prophylactic preconditioning exercise (PE) alone or in combination with post-TBI Yisaipu treatment on moderate TBI associated deficits were examined. The results showed that combined treatments of PE and post-TBI Yisaipu were superior to single treatments on reducing sensorimotor and gait dysfunctions in mice. These functional improvements were accompanied by reduced systemic inflammation largely via decreased serum TNF-α, boosted autophagic flux, and mitigated lesion volume after TBI. Given these neuroprotective effects, composite approaches such as a combination of exercise and TNF inhibitor may be a promising strategy for facilitating functional recovery from TBI and are worth further investigation.
