Nature Methods:科学家研发人工胸腺,有望逆转癌症治疗

2017-04-05 佚名 来宝网

加州大学洛杉矶分校(UCLA)的研究小组创建了一个全新的系统来产生人类T细胞,这种白细胞可以对抗外来病毒的侵略,系统工程师可以利用这一系统来发现并攻击癌细胞,这就意味着我们向战胜癌症又前进了一步。

加州大学洛杉矶分校(UCLA)的研究小组创建了一个全新的系统来产生人类T细胞,这种白细胞可以对抗外来病毒的侵略,可以利用这一系统来发现并攻击癌细胞,这就意味着我们向战胜癌症又前进了一步。

完整的研究报告发表于《NATURE METHODS》杂志中。

胸腺位于心脏前,在整个免疫系统中发挥着至关重要的作用,它使用血液干细胞生成T细胞,帮助身体抵抗感染,有能力消除癌细胞。然而,随着人们年龄的增长或生病,胸腺没有有效地使T细胞。胸腺中生成T细胞是需要专门的分子的,也称之为受体,这些受体帮助T细胞找到病毒来源或者癌细胞。利用好这一过程有可能成为治疗癌症的有效途径,科学家发现,用这些特定的癌细胞发现受体层层包围T细胞在临床阶段取得了可喜的效果,这一过程被称为T细胞过继免疫治疗。

T细胞过继免疫治疗的过程包括,首先从癌症患者体内取得T细胞,在实验室中,将这些T细胞把癌症发现受体结合,继而再注入回病人体内。

然而,T细胞过继免疫治疗可能需要耗费一定的时间,而且癌症患者体内是否有充足的T细胞也是一个问题。因此,研究小组用这些成分创建了人工胸腺,结构宛如人的胸腺,可以从血液中生成T细胞,科学家发现人工胸腺中可以生成大量的T细胞,它们与癌症发现受体相结合,作用工程与人体的胸腺非常相似。

相信这一研究可以为癌症治疗带来逆转性的新方法。
