1) desensitization
[英][,di:'sensətaɪz] [美][di'sɛnsə'taɪz]
失敏
1.

当持续施加激动剂时,GABAA受体进入失敏状态,并且许多因素参与调节GABAA受体的失敏,如受体亚基构成、配体与受体的亲合力、磷酸化作用、膜电压的变化等都会影响受体的失敏过程。
2) Calcium desensitization
钙失敏
1.
Our previous studies showed that the vascular hyporeactivity is not only caused by the functional disorder of the K+ and Ca2+ cannels in vascular smooth muscle cell (VSMC), the hyperpolarization of VSMC membrane, but also by the calcium desensitization (the decrease of force/Ca2+ ratio) in VSMC.
严重创伤/休克失代偿期常出现血管低反应性,主要表现为全身血管对缩血管物质和舒血管物质的反应降低或不反应,本实验室前期研究发现,除了以往认识的血管低反应性发生的血管平滑肌细胞(vascular smooth muscle cell,VSMC)的K+和Ca2+通道功能障碍、VSMC膜超极化之外,钙失敏(Ca2+ desensitization),即血管平滑肌细胞收缩蛋白对钙的敏感性(calcium sensitivity)降低,也就是力/钙比率(Force/Ca2+ ratio)和肌肉收缩效率的降低,也是休克血管低反应性发生的重要原因;蛋白激酶C (Protein kinase C,PKC)参与了休克后血管反应性和钙敏感性的调控。
