Calcitonin gene-related peptide (CGRP) was tested for possible interactions with the effects of substance P on rabbit skeletal muscle arterioles in vivo. Both CGRP and substance P dose-dependently increased arteriolar diameter. However, pretreatment with CGRP made the arterioles insensitive to substance P, and also prevented the formation of aggregates of leukocytes and platelets normally seen after substance P. These results suggest that CGRP, in addition to its direct effects, may act as a modulator of the effects of substance P in neurogenic inflammation.
对降钙素基因相关肽(CGRP)进行了检测,以研究其在体内与P物质对兔骨骼肌小动脉的作用之间可能存在的相互作用。CGRP和P物质均可使小动脉直径呈剂量依赖性增加。然而,用CGRP预处理可使小动脉对P物质不敏感,并且还可阻止通常在P物质作用后出现的白细胞和血小板聚集的形成。这些结果表明,CGRP除了具有直接作用外,在神经源性炎症中可能还作为P物质作用的调节剂。
