概括
化学抗原受体 (CAR) T细胞疗法对多发性骨髓瘤具有前景,但需要进行安全控制. 抗体与药物联合体 (ADC) 提供了一种新有效的消除CAR-T细胞的方法,提高了治疗的安全性.
科学领域:
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 细胞疗法细胞疗法
背景情况:
- 化学抗原受体 (CAR) T细胞疗法已经彻底改变了多发性骨髓瘤的治疗方法,但患者的复发仍然是一个挑战.
- 染色体1q的增加与多发性骨髓瘤的预后不佳有关,这凸显了对像SLAMF7.7这样的CAR-T标的需求.
- 新型CAR目标需要可控制的系统来减轻点,瘤外的毒性.
研究的目的:
- 系统地评估基于药理和抗体的策略来调节CD19和SLAMF7导向的CAR-T细胞.
- 为CAR-T疗法开发一个效应细胞独立的安全机制.
主要方法:
- 评估了氨酸激酶抑制剂达沙替尼作为CAR-T抑制剂.
- 对CAR-T细胞清除进行评估的抗体依赖细胞介导细胞毒性 (ADCC).
- 开发并测试了用于选择性CAR-T细胞清除的抗体-药物联合体 (ADC).
主要成果:
- 达沙替尼抑制了CAR-T激活,但也影响了未经修饰的T细胞.
- 基于ADCC的清除受到fludarabine/cyclophosphamide诱导的NK细胞枯竭和SLAMF7+NK细胞兄弟杀伤的限制.
- 针对BCMA的ADC贝兰塔马布-马福多丁可以选择性地消除BCMA表达的CAR-T细胞,而不会伤害未经修饰的T细胞.
结论:
- 在CAR-T疗法中,ADCs是一个强大的,效应细胞独立的安全开关.
- 这一策略提高了CAR-T细胞治疗在多发性骨髓瘤的未来临床应用的可控性和安全性.

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Tumor Immunotherapy
2.0K
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Combination Therapies and Personalized Medicine
6.2K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
