- 呼吸系统医学 呼吸系统医学
- 生物标志物发现发现
背景情况:
- 喘是一个普遍存在的全球健康问题,病原体的理解不佳.
- 免疫细胞透在喘病理学中起着至关重要的作用.
研究的目的:
- 为了确定喘的潜在生物标志物.
- 分析免疫细胞透在喘发病过程中的作用.
主要方法:
- 从诱导唾液数据集 (GSE76262,GSE137268) 中分析了基因表达特征.
- 机器学习算法 (LASSO,SVM-RFE) 确定了类似收费受体7 (TLR7) 作为核心基因.
- CIBERSORT算法评估了免疫细胞透差异;TLR7表达在患者样本中得到了验证.
主要成果:

Asthma-II: Pathophysiology and Classification
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:
Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
