Catecholamines are key modulators of ventricular repolarization patterns in the ball python (Python regius)
Boukens and colleagues show that changes in ventricular repolarization in the ectothermic ball python are modulated by the sympathetic nervous system and not directly by changes in temperature. Their work shows that regulation of this process is conserved between pythons and mammals.
The versatile regulation of K2P channels by polyanionic lipids of the phosphoinositide and fatty acid metabolism
Riel et al. screened K+ channels of the K2P family for sensitivity to polyanionic lipids, such as PIP2 and oleoyl-CoA. They show that these lipids activate or inhibit individual channels with different affinity and establish them as potential effectors to regulate channel activity.
