三个Sjögren病 (SjD) 患者群体显示出不同的生物标志物和干扰素 (IFN) 签名模式. 在B细胞活跃,低症状 (BALS) 集群中的高IFN特征预测疾病进展和淋巴瘤风险.
科学领域:
- 免疫学 免疫学 免疫学
- 类风湿病学 类风湿病学
- 遗传学 遗传学 是一个
背景情况:
- 斯约格伦病 (SjD) 呈现出不同的临床表现.
- 最近的集群分析发现了三个表型:B细胞活跃低症状 (BALS),高系统活性 (HSA) 和低系统活性高症状 (LSAHS).
- 了解不同的SjD表型对于向治疗至关重要.
研究的目的:
- 调查与SjD患者集群相关的不同生物标志物.
- 为了评估这些集群中干扰素 (IFN) 签名的预后值.
- 为了将IFN签名与疾病演变和治疗结果相关联.
主要方法:
- 对20年期望Sjögren综合征队列的分析 (n=395).
- 包括IFN-α2,IFN-γ,CXCL10,CXCL13,BAFF,IL-7和TNF-RII在内的生物标志物的比较.
- 通过转录基因分析和与临床结果的相关性评估IFN签名.
主要成果:
- 在BALS,HSA和LSAHS集群中观察到不同的生物标志物概况.
- 一个高的IFN签名,主要是由I型IFN (IFN-α2) 驱动的,在BALS集群中普遍存在.
- 在BALS患者中,高IFN标志与免疫抑制剂使用增加相关 (HR 9.38),并且存在于所有淋巴瘤病例中.
结论:
- 这三个SjD群体表现出独特的病理生理机制,反映在IFN签名和免疫细胞激活标志物中.
- 一个高的IFN签名作为一个潜在的预测器的系统演变在BALS SjD集群.
- 这些发现凸显了IFN通路在SjD病变和预后中的重要性.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
