PGE2 receptors, chloride channels: and EETinduced relaxations,Used

Endothelial cells play a central role in cardiovascular homeostasis by generation of numerous vasoconstrictors and vasodilators. One of the vasodilators is the endotheliumderived hyperpolarizing factor (EDHF). The identity of EDHF is not completely clear but a widely accepted candidate is epoxyeicosatrienoic acids (EETs). Firstly, we convincingly showed that the relaxing effect of 14,15EET is mediated through the Gs proteincoupled EP2 receptors which were linked to the cAMP/PKAdependent pathway. Secondly, we demonstrated that the effects of arterial size, aging and hypertension on the vasorelaxing response of EETs were due to the different expressions of EP2 receptor. Thirdly, wholecell patch clamp study demonstrated that EETs inhibited volumeactivate Cl channels in rat mesenteric arterial smooth muscle cells through a cGMP and cAMPdependent pathway. Finally, we showed the inhibition of Cl channels potentiated the EDHFmediated relaxation in rat mesenteric arteries. The mechanism probably involved the enhanced opening of Kir channels. It is hoped that the findings in this study can provide a better understanding of the physiology and pathophysiology of vascular system.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
