WebbOne of the CXCR2 antagonists, MK-7123, showed improved FEV 1 in comparison to placebo in patients with COPD, and it has also been investigated in Phase II clinical trials. 168. Other potential therapeutic targets include the regulation of signaling pathways – for example, by p38 mitogen-activated protein kinase (p38 MAPK). p38 MAPK inhibitors ... The cardiac action potential differs from the neuronal action potential by having an extended plateau, in which the membrane is held at a high voltage for a few hundred milliseconds prior to being repolarized by the potassium current as usual. This plateau is due to the action of slower calcium channels opening and holding the membrane voltage near their equilibrium potential even after the s…
