Aging impairs MA dilation by reducing the ability of sensory nerves to counteract sympathetic vasoconstriction. This study tested whether altered SMC Ca2+ signals to sympathetic (NE) and sensory (CGRP) neurotransmitters underlie aging‐related deficits in vasodilation.

衰老改变小鼠肠系膜动脉平滑肌细胞的自发性和神经递质介导的Ca 2+信号传导。

衰老通过降低感觉神经抵抗交感性血管收缩的能力而损害了MA的扩张。这项研究测试了向交感神经(NE)和感觉神经(CGRP)神经递质改变的SMC Ca 2+信号是否是与年龄相关的血管舒张功能缺陷的基础。
