Military personnel are often exposed to silica dust during combat operations across the globe. Exposure to silica dust in US military or service personnel could cause Desert Strom Pneumonitis also referred to as Al Eskan disease causing several organs damage and precipitate autoimmune dysfunction. However, the effects of microfine particles of sand inhalation-induced brain damage on the pathophysiology of traumatic brain or spinal cord injury are not explored. Previously intoxication of silica nanoparticles (50-60 nm size) is shown to exacerbates spinal cord injury induces blood-spinal cord barrier breakdown, edema formation and cellular changes. However, the mechanism of silica nanoparticles-induced cord pathology is still not well known. Spinal cord injury is well known to alter serotonin (5-hydroxytryptamine) metabolism and induce oxidative stress including upregulation of nitric oxide synthase and tumor necrosis factor alpha. This suggests that these agents are involved in the pathophysiology of spinal cord injury. In this review, we examined the effects of combined nanowired delivery of monoclonal antibodies to neuronal nitric oxide synthase (nNOS) together with tumor necrosis factor alpha (TNF-α) antibodies and a potent antioxidant H-290/51 to induce neuroprotection in spinal cord injury associated with silica nanoparticles intoxication. Our results for the first time show that co-administration of nanowired delivery of antibodies to nNOS and TNF-α with H-290/51 significantly attenuated silica nanoparticles-induced exacerbation of spinal cord pathology, not reported earlier.
军事人员在全球的作战行动中经常接触到二氧化硅粉尘。美国军事或服务人员接触二氧化硅粉尘可能会导致沙漠风暴肺炎,也称为 Eskan 病,导致多个器官损伤和自身免疫功能障碍。然而,吸入微纳米沙粒引起的脑损伤对创伤性脑或脊髓损伤的病理生理学的影响尚未得到探索。以前的研究表明,二氧化硅纳米粒子(50-60nm 大小)的中毒会加重脊髓损伤诱导的血脊髓屏障破坏、水肿形成和细胞变化。然而,二氧化硅纳米粒子诱导的脊髓病理学的机制仍不清楚。众所周知,脊髓损伤会改变 5-羟色胺(5-羟色胺)代谢并诱导氧化应激,包括一氧化氮合酶和肿瘤坏死因子-α的上调。这表明这些因子参与了脊髓损伤的病理生理学过程。在这篇综述中,我们研究了联合纳米线传递神经元型一氧化氮合酶(nNOS)单克隆抗体与肿瘤坏死因子-α(TNF-α)抗体以及一种有效的抗氧化剂 H-290/51 对二氧化硅纳米粒子中毒相关脊髓损伤的神经保护作用。我们的研究结果首次表明,nNOS 和 TNF-α抗体与 H-290/51 的联合纳米线传递显著减轻了二氧化硅纳米粒子诱导的脊髓病理学恶化,这在以前的研究中没有报道过。
