概括
降低TH17细胞数量可能表明主要免疫缺陷,如高IgE综合征 (HIES) 和慢性粘膜皮质候群病 (CMCD). 17%测量是一种敏感的查工具,但分子遗传学对于确定的诊断至关重要.
科学领域:
- 免疫学 免疫学 免疫学
- 遗传学 遗传学 是一个
- 临床诊断 临床诊断 临床诊断
背景情况:
- 主要免疫缺陷,如信号传感器和转录3 (STAT3) 相关的激活器超IgE综合征 (HIES) 和STAT1相关的慢性粘膜皮质候群病 (CMCD),其特点是TH17细胞数量减少.
- 诊断HIES和CMCD传统上依赖于临床表现和分子遗传检测.
研究的目的:
- 在怀疑患有HIES或CMCD的患者中,评估TH17%测量的诊断效用.
- 为了确定TH17%是否可以作为这些条件的有效查生物标志物.
主要方法:
- 分析了一组160名患者的队列,TH17%测量从2019-2022年.
- 临床数据,分子遗传结果和国家卫生研究院-HIES评分对52名低TH17% (<0.4%) 的患者和58名正常TH17%的患者进行了审查.
主要成果:
- 在52名TH17%的患者中,27人 (51.92%) 在STAT1,STAT3,DOCK8或AIRE中具有致病性或可能致病性 (P/LP) 变异.
- 在正常TH17%的患者中,这些基因中没有发现引起疾病的变异.
- 升高的IgE水平,肺炎和病理性骨折与HIES诊断有关.
结论:
- TH17%的测量显示了在STAT3,DOCK8和STAT1.1中识别P/LP变异的高灵敏度.
- 虽然TH17%是排除这些遗传变异的有价值的查工具,但分子遗传测试仍然是确定诊断的必不可少.

T Cell Types and Functions
2.1K
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

Immunodeficiency Diseases
1.9K
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
