概括
在血液细胞移植 (HCT) 之前,患有不良健康社会决定因素 (SDOH) 的患者表现出更高的逆境转录保护反应 (CTRA) 水平. 这种应激反应可能会将社会因素与HCT结果联系起来,这表明了新的治疗目标.
科学领域:
- 血液学 血液学 血液学
- 基因组学就是基因组学.
- 心理神经免疫学 心理神经免疫学
背景情况:
- 患者报告的结果 (PROs) 捕捉了通过压力路径影响健康的健康社会决定因素 (SDOH).
- 对逆境的保存转录反应 (CTRA) 是一种与压力相关的基因表达模式,与血造细胞移植 (HCT) 的不良结果有关.
研究的目的:
- 为了研究在异构HCT接受者中前HCTCTCT表达和患者报告的SDOH之间的关联.
主要方法:
- 通过全血RNA测序分析分析HCT前SDOH PROs (SF-36,FACT-BMT) 和CTRA表达的横截面研究.
- 对共变量 (年龄,性别,种族,疾病,性能状态) 进行控制的混合效应线性回归模型.
主要成果:
- 较高的CTRA表达与较低的FACT-BMT得分有关,特别是在社会福利领域 (P = .0001).
- 这种关联代表了CTRARNA表达在4SD范围的SDOH中8-15%的差异.
- 生物信息学证实,幸福与减少的促炎途径活性相关 (CREB,NF-κB,AP-1).
结论:
- 经历不良社会条件的HCT患者在移植前的CTRA表达率较高.
- 这突出了社会福祉的生物学影响,并表明了影响HCT结果的社会梯度的分子机制.
- 针对CTRA途径可能会改善这一高风险人群的治疗结果.

Regulation of Hematopoietic Stem Cells
3.2K
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...

Bone Marrow Sampling and Transplants

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...
