Theracurmin is a nanoparticle formulation derived from curcumin, a bioactive compound known for its antioxidant and anti-inflammatory properties. , the etiological agent of Chagas disease, triggers an intense inflammatory response in mammals and also causes severe tissue damage. To evaluate the immunomodulatory and antiparasitic effects of Theracurmin, Swiss mice were experimentally infected with 10 trypomastigote forms of the Colombian strain of and submitted to daily therapy with 30 mg/kg of Theracurmin. In addition, daily benznidazole therapy (100 mg/kg) was performed as a positive control. We evaluated the systemic and tissue parasitism, the survival and the body mass rate, the release of inflammatory mediators (TNF, IL-6, IL-15, CCL2 and creatine kinase) and the tissue inflammation at day 30 post-infection. Theracurmin therapy reduced the parasitemia curve without altering the animals' survival rate, and it protected mice from losing body mass. Theracurmin also reduced CCL2 in cardiac tissue, IL-15 in cardiac and skeletal tissue, and plasma CK. Even without effects on TNF and IL-6 production and tissue amastigote nests, Theracurmin reduced the leukocyte infiltrate in both evaluated tissues, even in the case of more effective results observed to the benznidazole treatment. Our data suggest Theracurmin has an immunomodulatory (CCL2, IL-15, CK and tissue leukocyte infiltration) and a trypanocidal effect (on circulating parasites) during experimental infection triggered by the Colombian strain of . Further investigations are necessary to comprehend the Theracurmin role performed in combination with benznidazole or other potential anti- chemical compounds.
Theracurmin是一种源自姜黄素的纳米颗粒制剂,姜黄素是一种具有抗氧化和抗炎特性的生物活性化合物。克氏锥虫,恰加斯病的病原体,在哺乳动物中引发强烈的炎症反应,还会导致严重的组织损伤。为了评估Theracurmin的免疫调节和抗寄生虫作用,将瑞士小鼠用10个克氏锥虫哥伦比亚株的锥鞭毛体形式进行实验性感染,并每天用30mg/kg的Theracurmin进行治疗。此外,每天进行苯硝唑治疗(100mg/kg)作为阳性对照。我们在感染后第30天评估了全身和组织寄生虫感染情况、存活率和体重率、炎症介质(TNF、IL-6、IL-15、CCL2和肌酸激酶)的释放以及组织炎症。Theracurmin治疗降低了寄生虫血症曲线,而不改变动物的存活率,并且保护小鼠不丢失体重。Theracurmin还降低了心脏组织中的CCL2、心脏和骨骼肌组织中的IL-15以及血浆CK。即使对TNF和IL-6的产生以及组织无鞭毛体巢没有影响,Theracurmin也减少了两个评估组织中的白细胞浸润,即使在观察到苯硝唑治疗效果更显著的情况下也是如此。我们的数据表明,在由克氏锥虫哥伦比亚株引发的实验性感染期间,Theracurmin具有免疫调节作用(对CCL2、IL-15、CK和组织白细胞浸润)和杀锥虫作用(对循环寄生虫)。需要进一步研究以了解Theracurmin与苯硝唑或其他潜在抗化学化合物联合使用时所起的作用。
