肺结核 (PTB) 的延迟诊断构成公共卫生风险. 这项研究确定了关键的分子参与者和监管网络,为PTB诊断和治疗提供了洞察力.
科学领域:
- 分子生物学分子生物学
- 免疫学 免疫学 免疫学
- 基因组学就是基因组学.
背景情况:
- 肺结核 (PTB) 的延迟诊断导致了重大的公共卫生挑战.
- 了解PTB背后的分子机制对于改善诊断和治疗策略至关重要.
研究的目的:
- 研究PTB肺组织中长非编码RNAs (lncRNAs),信使RNAs (mRNAs) 和microRNAs (miRNAs) 的差异表达.
- 构建一个竞争的内源性RNA (ceRNA) 调控网络,以阐明PTB的病原性.
- 分析PTB对T辅助细胞分化的影响.
主要方法:
- 高通量测序以在PTB病变和相邻的健康组织中描述lncRNA,mRNA和miRNA的表达.
- 生物信息分析包括差异表达分析,丰富分析和网络构建.
- 定量实时PCR (qRT-PCR) 用于基因表达的验证.
- 流细胞测量以评估T-辅助细胞种群.
主要成果:
- 在PTB病变和健康组织之间确定了146个差异表达的lncRNAs (DElncRs),447个DEmR和29个DEmiR.
- 丰富分析表明DEmRs参与Th1,Th2和Th17细胞分化.
- 建立了两个lncRNA介导的ceRNA网络,并验证了基因表达.
- 与对照组相比,在PTB患者中观察到Th1和Th17细胞比例下降,Th2细胞比例增加.
结论:
- 该研究为PTB研究提供了全面的转录组数据.
- 已识别的ceRNA调节网络为PTB诊断和治疗提供了潜在的目标.
- 改变T-辅助细胞分化与PTB相关,并且可能由已识别的分子网络调节.

Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
