- 细胞生物学 细胞生物学
背景情况:
- 大肠直肠癌 (CRC) 的预后和治疗反应各不相同.
- 对标准治疗的耐药性影响了一大批患者.
- 使用仿真抗原受体 (CAR) 转换细胞的采用免疫疗法提供了一个替代方案,但存在安全问题.
研究的目的:
- 评估介质素 (MSLN) 作为结直肠癌 (CRC) 的CAR标.
- 开发和测试用于CRC治疗的MSLN-CAR转化NK-92细胞.
- 评估这种新型免疫疗法方法的疗效和安全性.
主要方法:

Tumor Immunotherapy
476
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.

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.
