概括
在多发性硬化症 (MS) 中预测抗药抗体 (ADA) 的发展至关重要. 血液中的早期免疫特征可以识别可能患有ADA的患者,从而影响免疫治疗的疗效.
科学领域:
- 神经免疫学 神经免疫学
- 免疫学 免疫学 免疫学
- 生物标志物发现发现
背景情况:
- 抗药抗体 (ADA) 降低了多发性硬化症 (MS) 免疫治疗的有效性.
- 生物制药免疫性预测生物标志物是有效的MS治疗所需的.
- 干扰素β治疗是复发性复发性多发性硬化症 (RRMS) 的常见治疗方法.
研究的目的:
- 为了确定早期血液生物标志物,预测中和ADA的发展在RRMS患者开始干扰素-beta.
- 调查基线分子形状和随后的ADA形成之间的关系.
- 探索免疫性特征和多发性硬化症疾病严重性标志物之间的重叠.
主要方法:
- 在干扰素β治疗前和治疗期间招募RRMS患者 (基线,3个月和12个月).
- 基于M12中和ADA状态的患者分层 (ADA阳性与ADA阴性).
- 在基线和整个治疗期间进行全血转录和蛋白质分析.
主要成果:
- 在ADA检测之前,ADA阳性患者对干扰素β呈现出早期抑制反应.
- 在基线和整个治疗过程中,在ADA阳性患者中观察到明显的促炎外周血液特征,为免疫应答激活通路 (例如PI3K-γ,NFκB) 进行了丰富.

Chromatin Structure Regulates pre-mRNA Processing
In eukaryotic cells, nascent mRNA transcripts need to undergo many post-transcriptional modifications to reach the cell cytoplasm and translate into functional proteins. For a long time, transcription and pre-mRNA processing were considered two independent events that occur sequentially in the cell. However, it has now been well established that transcription and pre-mRNA processing are two simultaneous processes that are precisely regulated inside the cell.

Pulmonary Tuberculosis I
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
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.
