- 分析当前的治疗局限性和新出现的治疗方式.
- 探索新的治疗点,包括分子途径,新陈代谢和免疫调节.
主要成果:
- TP53突变会破坏正常的细胞功能,导致免疫规避和瘤微环境的改变.
- 目前的疗法在TP53突变的MDS和AML中有效性有限,与生存率差相关.
- 一系列新疗法,包括MDM2抑制剂,p53活性化剂,特定途径抑制剂,免疫调节剂,代谢干预和基因编辑,显示出有前途.
结论:
- 结合向药物,代谢干预和免疫调节的综合治疗方法是TP53突变的MDS和AML的一个有希望的策略.
- 解决TP53突变,瘤微环境和免疫功能障碍之间的复杂相互作用对于治疗成功至关重要.

02:17The Tumor Microenvironment
6.8K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

02:23Abnormal Proliferation
4.6K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
