概括

较低剂量的甲基prednisolone (MP) 在全身性红斑狼 (SLE) 患者中增加调节性T细胞 (Treg),减少炎症. 高剂量的MP脉冲疗法降低了Treg细胞,影响了免疫反应.

科学领域:

免疫学免疫学免疫学
药理学药理学是指药理学的学科.
类风湿病学类风湿病学

背景情况:

系统性红斑狼 (SLE) 是一种慢性自身免疫性疾病.
甲基prednisolone (MP) 是一种用于管理SLE的皮质类固醇.
需要进一步阐明MP对SLE淋巴细胞样本的剂量依赖性影响.

研究的目的:

研究甲基prednisolone (MP) 对系统性红斑狼 (SLE) 患者的周围淋巴细胞数量和亚种群的剂量依赖作用.
为了比较标准和高剂量脉冲MP治疗对SLE中调节性T细胞 (Treg) 和效应性T细胞 (Teff) 的影响.

主要方法:

一项前性研究涉及51名SLE患者,接受不同剂量的MP治疗 (40,80,500,1000毫克/天).
在MP治疗前后对外围血液淋巴细胞数量,比例和亚群 (T细胞,CD4+T细胞,Treg,Teff) 的分析.
使用对联曼-惠特尼U测试进行统计分析.

主要成果:

临床合理剂量 (40-80毫克/天) 的MP暂时增加了总淋巴细胞,T细胞,CD4+T细胞,Treg和Teff数量.
高剂量脉冲MP (每天500-1000毫克) 减少了这些淋巴细胞子集.
较低的MP剂量增加了Treg百分比和Treg/Teff比率,而脉冲疗法则降低了它们,脉冲疗法停止后Treg迅速恢复.

结论:

短期内,较低剂量的MP增强Treg细胞,可能抑制SLE的全身炎症.
高剂量的MP脉冲疗法表明对Treg细胞有抑制作用.
在SLE治疗中,MP剂量极大地影响了外围淋巴细胞子集,对Treg细胞有明显的影响.

关键词:

T Cell Types and Functions

T Cell Types and Functions

When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids

Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids

Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2...
