Abstract

Currently, there are no approved therapeutic drugs for the treatment of traumatic brain injury (TBI), and new targets and approaches are needed to provide relief from the long-term effects of TBI. Recent studies suggest that nutrition plays a critical role in improving the outcome from TBI in both civilians and military personnel. We have previously shown that GrandFusion (GF) diets improved recovery from cerebral ischemia and enhanced physical activity and endurance in rodent models. We, therefore, sought to determine the impact of a prophylactic diet enriched in fruits and vegetables on recovery from TBI in the controlled cortical impact rodent model. Results demonstrated that mice fed the diets had improved neuromotor function, reduced lesion volume, increased neuronal density in the hippocampus and reduced inflammation. As previously shown, TBI increases cathepsin B as part of the inflammasome complex resulting in elevated inflammatory markers like interleukin-1β (IL-1β). Consumption of the GF diets attenuated the increase in cathepsin B levels and prevented the increase in the proapoptotic factor Bax following TBI. These data suggest that prior consumption of diets enriched in fruits and vegetables either naturally or through powdered form can provide protection from the detrimental effects of TBI.

摘要

目前,尚无治疗创伤性脑损伤(TBI)的批准治疗药物,需要新的靶点和方法来缓解 TBI 的长期影响。最近的研究表明,营养在改善平民和军人的 TBI 预后方面起着关键作用。我们之前已经表明,GrandFusion(GF)饮食可改善脑缺血后的恢复,并增强啮齿动物模型的体力活动和耐力。因此,我们试图确定富含水果和蔬菜的预防性饮食对受控皮质撞击啮齿动物模型中 TBI 恢复的影响。结果表明,喂食这些饮食的小鼠神经运动功能得到改善,损伤体积减小,海马神经元密度增加,炎症减少。如前所述,TBI 会增加组织蛋白酶 B 作为炎症小体复合物的一部分,导致白细胞介素 1β(IL-1β)等炎症标志物升高。GF 饮食的消耗减弱了组织蛋白酶 B 水平的增加,并防止了 TBI 后促凋亡因子 Bax 的增加。这些数据表明,先前食用富含水果和蔬菜的饮食(无论是天然的还是通过粉末形式)都可以提供对 TBI 有害影响的保护。
