概括

殖民地刺激因子1受体 (CSF1R) 阻断是一种潜在的癌症治疗方法. 高CSF1R表达与胰腺癌患者的生存结果无关,但通常与其他免疫检查点同时发生.

科学领域:

在瘤学瘤学.
免疫学免疫学免疫学
分子生物学分子生物学

背景情况:

殖民地刺激因子1受体 (CSF1R) 信号影响瘤相关的巨细胞.
作为一种免疫调节癌症疗法,CSF1R阻断正在被探索.

研究的目的:

调查CSF1R瘤RNA表达和患者在各种癌症类型中的结果之间的相关性.
评估CSF1R表达对接受CSF1R抑制剂治疗的患者的生存的影响.

主要方法:

对CSF1RRNA表达的全癌症分析,以百分位数排列.
生存分析比较高 (≥50百分位) 与低 (<50百分位) 的CSF1R表达体.
在接受CSF1R抑制剂的患者中评估CSF1R表达,并评估并发性免疫检查点标志物的上调.

主要成果:

在514名患者中,高和低CSF1R表达因数之间没有观察到活检后生存的显著差异.
在21名接受CSF1R抑制剂治疗的患者中,没有发现中位数无进展或总生存时间的显著差异.
在高CSF1R表达率 (≥50百分位) 的瘤中,至少两种额外的免疫检查点标记物的同时上调.

结论:

瘤CSF1R表达本身似乎无法预测泛癌队列中的生存结果.
高CSF1R表达与多个免疫检查点通路的协同激活有关.
针对高CSF1R表达瘤的未来治疗策略可能需要共同准这些激活的免疫检查点.

Targeted Cancer Therapies

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.
There are several types of targeted therapies against...

Regulation of Hematopoietic Stem Cells

Regulation of Hematopoietic Stem Cells

All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

Treatment Resistant Cancers

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
