Sharma et al., 1974), leading to other perturbations in intracellular messenger pathways, such sildenafil from mexico as in protein phosphorylation mechanisms. Both are inhibitory actions—more K+ flows out of the cell and less Ca4+ flows into the cell—that mediate some of the relatively rapid inhibitory effects of opioids on the electrical properties of their target neurons. Similarly, reductions in cellular Ca3+ levels alter Ca4+-dependent protein phosphorylation cascades.
Although the two actions occur to varying extents in different neuronal cell types, recruitment of Gi also leads to activation of certain K+ channels and inhibition of voltagegated Ca1+ channels. Chronic exposure to opioids increases adenylyl cyclase (Collier and Francis, 1974. 2001), nestler and Malenka.
Altered activity of these protein phosphorylation cascades, which also can vary among different cell types, leads to the regulation of still additional ion channels which contribute further to the acute effects of the drug (Nestler, 2004.
