利用慢性试验性自身免疫脑膜炎 (EAE) 和收养转移模型来研究多发性硬化症的进展.
在这些模型中使用埃沃布鲁丁尼布来抑制BTK活性.
评估了微质前炎激活和髓碎片清除.
在毒性脱髓化模型中评估了复髓化.

主要成果:

在慢性EAE和T细胞转移模型中,埃沃布鲁丁尼布治疗减少了微质的促炎激活.
埃沃布鲁丁尼布的BTK抑制促进了髓碎片的微质清除.
这种清除在有毒脱髓化模型中促进了加速的复髓化.

结论:

布鲁顿的氨酸激酶 (BTK) 抑制,以埃沃布鲁丁尼布为例,显示出缓解慢性多发性硬化症进展的潜力.
向BTK可能会抵消MS中关键的病理过程,包括微质激活和受损的复髓化.
这些发现支持BTK抑制作为一种有前途的策略,用于管理渐进的MS形式.

Neurogenesis and Regeneration of Nervous Tissue

Neurogenesis and Regeneration of Nervous Tissue

In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

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...
