背景情况:

创伤诱导的异型骨化 (THO) 与疼痛和感觉诱导的神经炎症 (NINI) 有关.
感觉神经在受伤时释放神经炎症,如物质P (SP) 和素基因相关 (CGRP).
在受伤时释放的骨形态遗传蛋白-2 (BMP-2) 激活TRVP1受体,加剧神经炎症和血神经屏障的破坏.

研究的目的:

阐明NINI和CGRP在THO启动和进展中的作用.
调查参与CGRP介导骨质生成差异化的信号通路.

主要方法:

在THO中,分析连接 nociception,神经炎症和骨质生成的分子机制.
检查BMP-2,TRVP1受体和下游信号通路的激活.

主要成果:

NINI,特别是CGRP诱导,对于THO至关重要.
通过BMP-2和Wnt/β-catenin信号传递,CGRP直接促进原生细胞的骨质分化.
BMP-2信号激活SMAD1/5/8和SMAD4,这对骨质生成相关的基因表达至关重要.

结论:

尼尼表型,特别是CGRP,是THO的关键驱动因素.
血液神经屏障的破坏使神经衍生原生细胞 (NCDPCs) 能够分化为骨.
准NINI和CGRP可能为THO提供治疗策略.

Blood and Nerve Supply to the Bones

Blood and Nerve Supply to the Bones

Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

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...
