炎症研究炎症研究

背景情况:

复发性口腔口腔炎 (RAS) 是一种常见的慢性口腔疾病,原因尚不清楚.
在RAS中,慢性炎症与局部免疫反应的破坏有关.
了解免疫微环境对于开发有效治疗方法至关重要.

研究的目的:

为了研究化学口腔炎 (CS) 鼠标模型中的免疫变化.
阐明IL-6-Th17-中性粒细胞轴在口腔炎发病过程中的作用.
为了探索潜在的免疫治疗对口腔炎的点.

主要方法:

在小鼠模型中,乙酸诱导的化学口腔炎 (CS).
流细胞计分析免疫细胞种群 (中性粒细胞,Th1,Th17).
Th17细胞 (Rorc-/-小鼠) 和IL-6受体信号传递 (Il6ra-/-小鼠) 的遗传衰竭.
治疗抗Ly6G抗体以减少中性粒细胞的数量.
组织病理学分析 (血素和欧染色) 用于组织损伤的评估.

主要成果:

在CS小鼠中,中性粒细胞透率增加,语言粘膜中Th1/Th17细胞升高.
Th17细胞的枯竭 (Rorc-/-) 减少了中性粒细胞的透和组织损伤.
损害IL-6受体信号传递 (Il6ra-/-) 降低了炎症细胞透和的严重程度.
中性粒细胞的减少减少了Th1/Th17细胞的透,这表明了反循环.

结论:

IL-6-Th17-中性粒细胞轴是口腔炎发病的关键驱动因素.
这个轴在Th17细胞和中性粒细胞之间创建了一个正反循环.
针对这一轴,为口腔炎提供了一个有前途的免疫治疗策略.

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...

Inflammatory Response

Inflammatory Response

An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...
