下一代肿瘤不可知靶点即将出现
Next-generation tumor-agnostic targets on the horizon.
肿瘤不可知药物开发将肿瘤学重新聚焦于共享的分子依赖性而非组织来源,从而能够针对跨肿瘤的罕见可操作驱动因素进行高效开发。
英文原题:Adoptive T Cell Therapy Targeting MAGE-A4.
MAGE A4(黑色素瘤抗原基因A4)是一种癌睾丸抗原(CTA),在生殖细胞(睾丸/胚胎组织)中正常表达,但在体细胞中不表达。
MAGE A4(黑色素瘤抗原基因A4)是一种癌睾丸抗原(CTA),正常表达于生殖细胞(睾丸/胚胎组织),但在体细胞中不表达。MAGE A4 CTA在多种肿瘤类型中表达,如滑膜肉瘤、卵巢癌和非小细胞肺癌。由于其表达谱仅限于生殖细胞,MAGE A4已成为某些恶性肿瘤中备受追捧的免疫治疗靶点。在这篇综述中,我们重点关注MAGE-A4的功能和表达、当前涉及靶向免疫治疗方法的临床试验,以及MAGE-A4靶向治疗面临的挑战和机遇。
MAGE A4 (Melanoma Antigen Gene A4) is a cancer testis antigen (CTA) that is expressed normally in germline cells (testis/embryonic tissues) but absent in somatic cells. The MAGE A4 CTA is expressed in a variety of tumor types, like synovial sarcoma, ovarian cancer and non-small cell lung cancer. Having its expression profile limited to germline cells has made MAGE A4 a sought-after immunotherapeutic target in certain malignancies. In this review, we focus on MAGE-A4's function and expression, current clinical trials involving targeted immunotherapy approaches, and challenges and opportunities facing MAGE-A4's targeted therapeutics.
