receptors. • Modulates glutamate receptors in brain
• Causes vasodilation by stimulating ATPsensitive K+ channel in smooth muscle HS cause different way of vasodilation than NO. by stimulating an ATP-gated potassium channel in
smooth muscle. many potassium ion channel are modulated by different things. there's a class of
Potassium channel are modulate by intracellular ATP. ATP open potassium channel. that ATP-gated
potassium channel is modulated/stimulated by HS. HS increase potassium permeability of cell,
hyperpolarize the cell which closes voltage-gated calcium channels, decrease calcium influx, lead to
relaxation of smooth muscle, causing vasodilation in vascular smooth muscle....
