靶向巨噬细胞的癌症治疗策略
Macrophage-directed therapeutic strategies in cancer.
肿瘤相关巨噬细胞(TAMs)是肿瘤微环境的主要组成部分,具有显著的功能可塑性,根据所处的微环境信号,既可表现为促进肿瘤进展的免疫抑制细胞,也可表现为支持抗肿瘤免疫的免疫刺激细胞。
英文原题:Amivantamab: A New Hope in Targeting Non-small Cell Lung Cancer.
amivantamab 是一种新型双特异性抗体,通过两种不同途径靶向非小细胞肺癌,即与表皮生长因子受体和间质上皮转化因子结合。
背景:美国食品药品监督管理局于2021年5月21日批准amivantamab(商品名Rybrevant),用于成人表皮生长因子受体(EGFR)外显子20插入突变、局部晚期或转移性非小细胞肺癌。 目的:本综述介绍非小细胞肺癌及其与小细胞肺癌的分子差异,并总结amivantamab抑制癌细胞生长的作用特点、相关临床试验、不良反应及禁忌证。 方法:在ScienceDirect、PubMed、ResearchGate和Google Scholar等相关数据库进行全面文献检索。 结论:Amivantamab是一种新型双特异性抗体,可通过两条不同通路靶向非小细胞肺癌,即结合EGFR和间质-上皮转化因子(MET)。Amivantamab可高亲和力结合FcγRIII,进而介导巨噬细胞和NK细胞杀伤癌细胞。动物模型临床前数据表明,amivantamab生物治疗对EGFR外显子20插入突变有效。
BACKGROUND: Amivantamab was approved on May 21st, 2021, by United States food and drug administration with the brand name Rybervant, used particularly for adult patients with exon20 insertion of epithelial growth factor receptor with locally advanced metastatic non-small cell lung cancer. OBJECTIVE: In this review, we explain the non-small cell lung cancer and molecular distinctions between non-small cell lung cancer and small cell lung cancer. We also conclude numerous components of non-small cell lung cancer, which include signs and symptoms of Amivantamab in inhibiting the cancer cell growth, various clinical trials on Amivantamab, adverse effects, and the contraindications of Amivantamab. METHODS: A comprehensive literature search was conducted in the relevant databases like ScienceDirect, PubMed, ResearchGate, and Google Scholar to identify studies. CONCLUSION: Amivantamab is a new bispecific antibody that targets non-small cell lung cancer through two different pathways, i.e., by binding to epithelial growth factor receptor and mesenchymal epithelial transition factor. Amivantamab gets tightly bound to Fc 3R, and thus, mediates the macrophage and NK-cell for the killing of cancer cells. Biological treatment of Amivantamab shows effectiveness against the epithelial growth factor receptor Exon20 insertions according to the preclinical data of the animal model.
