Nature:纳米疗法对免疫细胞重编程 逆转自身免疫疾病

2016-02-19 佚名 生物谷

近日,来自Parvus Therapeutics公司的研究人员通过研究描述了公司新型纳米药物的治疗应用,相关研究刊登于国际杂志Nature上,研究者指出,这种新型纳米药物疗法可以对白细胞重编程使其成为可以钝化自身免疫反应并且帮助恢复免疫系统平衡状态的调控细胞。这种名为“Navacims”的纳米药物由包被有疾病相关的肽类主要组织相容性复合体(pMHCs)的纳米颗粒组成,pMHCs可以通过直接结合

近日,来自Parvus Therapeutics公司的研究人员通过研究描述了公司新型纳米药物的治疗应用,相关研究刊登于国际杂志Nature上,研究者指出,这种新型纳米药物疗法可以对白细胞重编程使其成为可以钝化自身免疫反应并且帮助恢复免疫系统平衡状态的调控细胞。这种名为“Navacims”的纳米药物由包被有疾病相关的肽类主要组织相容性复合体(pMHCs)的纳米颗粒组成,pMHCs可以通过直接结合其抗原受体来改变病理性的T淋巴细胞的行为。

研究者Santamaria指出,自身免疫疾病包括1型糖尿病、多发性硬化症及风湿性关节炎,患者机体中会发生相当复杂的反应,最终引发慢性器官炎症、器官异常,有时候甚至会引发早产儿死亡。而在不抑制机体抵御感染和癌症的正常免疫反应的前提下,钝化这些不良的免疫反应目前来讲是不太可能的。

本文研究中研究人员就为解决上述问题提供了一种药物策略,Navacims可以从本质上重编程引发疾病的白细胞来使其转变成为抑制疾病发生的调节性细胞,从而对多种自然性及实验性的自身免疫疾病的治疗提供策略。研究人员发现,候选药物Navacims可以有效治疗一系列自身免疫疾病,更重要的是其可以以对鼠类细胞同样的方式来影响人类机体的白细胞,基于研究结果研究者认为Navacims可以为治疗包括自身免疫疾病在内的一系列疾病提供一种治疗性的平台。

研究者Santamaria的工作是研究引发1型糖尿病的免疫系统失调发生的机制,他认为这种新型纳米药物疗法可以有效帮助治疗相关的自身免疫疾病。目前Parvus公司向同其它大型的制药公司建立合作关系,共同进行流水线候选药物的临床试验和商业应用,一旦临床试验成功,这种Navacims纳米候选药物或有望帮助治疗一系列疾病。
