概括
干细胞移植后的免疫复合 (IR) 最好使用功能性免疫试验与细胞计数一起进行评估. 转录组分析揭示了仅仅在细胞计数中看不到的持续性功能缺陷,指导了个性化的患者管理.
科学领域:
- 免疫学 免疫学 免疫学
- 移植科学 移植科学
- 基因组学就是基因组学.
背景情况:
- 免疫复制 (IR) 后异质造血干细胞移植 (allo-HSCT) 通常通过免疫细胞计数进行监测.
- 这种定量方法可能不能完全反映免疫系统的功能能力.
研究的目的:
- 为了评估功能性IR在alo-HSCT接受者的时间演变.
- 将功能性免疫特征与传统免疫细胞计数进行比较.
主要方法:

Regulation of Hematopoietic Stem Cells
3.1K
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...

Cells of the Adaptive Immune Response
762
The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...
