概括
儿童流感可以导致长期多器官功能障碍综合征 (PMODS). 这项研究确定了PMODS的两个分子亚型,揭示了针对性干预的关键生物标志物,如CCL2和TNFSF10.
科学领域:
- 儿科重症监护医药 儿科重症监护医药
- 分子生物学分子生物学
- 免疫学 免疫学 免疫学
背景情况:
- 儿科流感患者长期多器官功能障碍综合征 (PMODS) 的死亡率很高.
- 人们对PMODS的分子机制和免疫微环境的了解很少,这阻碍了有效的治疗.
- 自途径调节失调是相关的,但需要进一步表征.
研究的目的:
- 整合转录组数据和机器学习来分析儿科PMODS中与自相关的基因 (ARG) 失调.
- 描述与PMODS相关的免疫微环境.
- 确定与PMODS严重程度相关的临床生物标志物.
主要方法:
- 对GSE236877转录组数据集 (191个儿科流感样本) 的分析.
- 对ARG的差异表达分析和未经监督的共识聚类以确定PMODS亚型.
- 免疫细胞透量化 (CIBERSORT) 和随机森林 (RF) 机器学习用于生物标志物识别.
主要成果:
- 与非MODS病例相比,PMODS病例显示出不同的ARG表达 (例如,上调的CCL2,HIF1A;下调的CASP1,TNFSF10).
- 确定了两种PMODS亚型:C1 (超炎症性,高CCL2,巨细胞M0透) 和C2 (亡性,高TNFSF10,低巨细胞M0透).
- 射频分析强调了CCL2,TNFSF10和HIF1A作为关键的歧视基因,与白细胞计数和临床严重程度相关.
结论:
- 儿童流感相关的PMODS表现出显著的分子异质性,具有明显的超炎症 (C1) 和亡 (C2) 亚型.
- CCL2,TNFSF10和HIF1A被确定为与免疫失调和临床严重程度相关的关键生物标志物.
- 这些发现支持为儿科PMODS开发分型特定的精确管理策略.

The Tumor Microenvironment
7.9K
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...

Adrenergic Receptors: ɑ Subtype
3.0K
Adrenoceptors are classified into α and ꞵ classes based on their potencies to catecholamine agonists. α-adrenoceptors show the following order of catecholamine potency:
Adrenaline ≥ Noradrenaline >> Isoprenaline
α-adrenoceptors are further divided into α1 and α2-adrenoceptors.
α1-Adrenoceptors: These receptors are located postsynaptically on the effector organs and cause constriction of smooth muscle mediated by activation of phospholipase...

Adrenergic Receptors: β Subtype
3.8K
β-adrenoceptors have varied sensitivities towards adrenaline, noradrenaline, and isoprenaline. The order of agonist potency is as follows:
Isoprenaline > Adrenaline > Noradrenaline
Neurotransmitter binding to these receptors causes activation of adenylyl cyclase resulting in increased concentrations of cAMP and modulation of calcium ion channels within the cell. They are further classified into β1, β2, and β3 subtypes.
β1-adrenoceptors: β1-adrenoceptors...
