- 在瘤学瘤学.
- 分子生物学分子生物学
背景情况:
- 脏细胞癌 (RCC) 仍然是瘤学中的一个重大挑战.
- 像PD-1这样的免疫检查点抑制剂是已知的疗法,但需要新的点.
- TIGIT (具有Ig和ITIM域的T细胞免疫受体) 是一个潜在的免疫检查点目标.
研究的目的:
- 调查TIGIT作为RCC的潜在免疫治疗点.
- 为了比较TIGIT抑制与RCC中PD-1抑制的疗效.
- 探索RCC中TIGIT和PD-1表达之间的相关性.
主要方法:
- 在RCC组织和外周血液单核细胞 (PBMC) 中评估TIGIT和PD-1表达.
- 评估TIGIT和PD-1表达与其他免疫标记物 (PDCD1,BTLA,ICOS,FOXP3) 的相关性.
- 抑制TIGIT和PD-1通路,以评估对RCC细胞增殖,亡和迁移的影响.
主要成果:
- 在RCC组织和PBMC中,TIGIT表达高于PD-1.
- 紧张的表达与PDCD1,BTLA,ICOS和FOXP3.3正相关.
- 抑制TIGIT和PD-1显著降低了RCC细胞的增殖和迁移,同时增加了细胞亡.

Tumor Immunotherapy
554
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.
