Blood:人源的Fc受体非结合型抗CD3单克隆抗体在T-ALL中的疗效

2020-06-07 QQY MedSci原创

人源的Fc受体非结合型抗CD3单克隆抗体可作为治疗T-ALL的新策略;在T-ALL PDX中,抗CD3单克隆抗体的抗白血病特性很大程度上独立于Fc受体途径。

T细胞急性淋巴细胞白血病(T-ALL)是一种侵袭性的恶性肿瘤,约占ALL病例的20%。强化化疗方案的儿童治愈率超过85%,但用于成人的治愈率不足50%,因此,我们需要寻找新的治疗策略。

虽然免疫疗法极大地改善了B-ALL和其他B细胞恶性肿瘤的治疗,但它们尚未应用于T-ALL。

Quang等发现,人源化的非FcgR结合的CD3单克隆抗体在CD3+ T-ALL的异种移植(PDX)模型中具有抗白血病特性。此外,这些抗体与化疗合用,可提高抗白血病的效应和宿主的存活率。

因为这些抗体在人体中只显示轻微的可控制的副作用,为治疗T-ALL提供了一种新的治疗选择。Quang等的结果还表明,在T-ALL PDX中,抗CD3单克隆抗体的抗白血病特性很大程度上是不依赖于Fcg受体介导的通路。
