神经科学是一个神经科学.
免疫学免疫学免疫学
细胞生物学细胞生物学

背景情况:

基底腺 (BG) 网络对于运动控制,认知和情绪至关重要.
免疫媒介的作用,比如Interleukin-17A (IL-17A),在BG功能中的作用基本上是未知的.
IL-17A在皮质中被认为是一种神经调节剂,但其皮质下作用尚不清楚.

研究的目的:

研究IL-17轴在BG电路的可塑性中的作用.
为了确定IL-17A是否影响状中等状神经元 (MSN) 的突触可塑性.

主要方法:

在MSN中IL-17受体A (IL-17RA) 表达的分析.
在野生型和IL-17A/IL-17RA淘汰小鼠中评估长期潜能 (LTP).
电生理学记录用于研究NMDAR电流和GluN2B表达.

主要成果:

MSN表达IL-17RA,表明对IL-17A的敏感性.
在缺乏IL-17A或IL-17RA的小鼠中,LTP诱导受损.
在IL-17A缺乏的小鼠中观察到GluN2B的突触表达减少和NMDAR电流的改变.
高度的IL-17A通过NMDAR调制损害了LTP诱导.

结论:

IL-17轴在BG电路内调节突触可塑性方面发挥着重要作用.
IL-17A对条状突触可塑性表现出双重影响.
这些发现表明,这些发现可能对涉及BG的神经炎症和神经精神疾病产生潜在影响.

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,...
