On the other hand , a positive inotropic response was induced by il - 2 in isolated rat atria , indirectly by activating myocardial 3 - adrenoceptors by release of catecholamines , and directly by increasing the production of second messenger camp . in the isolated rat heart , stimulation of cardiac k opioid receptors has been shown to induce ventricular ectopic beats and to reduce the force of ventricular contraction
通过文献调研和我们的预实验，我们假设， il - 2的心脏作用涉及心肌细胞收缩力和细胞内钙的变化，其信号转导途径可能并非通过自身受体，而是通过存在于心肌细胞膜上的阿片受体发挥作用的；其对血管的作用可能循相关途径。
