Abstract

Vascular smooth muscle cells (VSMCs) constitute the principal cellular component of the medial layer of arteries and are responsible for vessel contraction and relaxation in response to blood flow. Alterations in VSMCs can hinder vascular system function, leading to vascular stiffness, calcification and atherosclerosis, which in turn may result in life-threatening complications. Pathological changes in VSMCs typically correlate with chronological age; however, there are certain conditions and diseases, such as Hutchinson-Gilford progeria syndrome (HGPS), that can accelerate this process, resulting in premature vascular aging. HGPS is a rare genetic disorder characterized by severe VSMC loss, accelerated atherosclerosis and death from myocardial infarction or stroke during the adolescence. Because experiments with mouse models have demonstrated that alterations in VSMCs are responsible for early atherosclerosis in HGPS, studies on this disease can provide insights into the mechanisms of vascular aging and assess the relative contribution of VSMCs to this process.

血管平滑肌细胞老化:从Hutchinson-Gilford早衰综合征的见解
血管平滑肌细胞(VSMCs)构成动脉中层的主要细胞成分,负责血管对血流的收缩和舒张。VSMCs的改变会阻碍血管系统功能,导致血管硬化、钙化和动脉粥样硬化,进而可能导致危及生命的并发症。VSMCs的病理变化通常与年龄相关;然而,某些情况和疾病,如Hutchinson-Gilford早衰综合征(HGPS),会加速这一过程,导致血管过早衰老。HGPS是一种罕见的遗传性疾病,其特征是青少年时期VSMC严重丧失、动脉粥样硬化加速以及心肌梗死或中风死亡。因为用小鼠模型进行的实验已经证明,VSMCs的改变是HGPS早期动脉粥样硬化的原因,所以对这种疾病的研究可以深入了解血管老化的机制,并评估VSMCs对这一过程的相对贡献。
