NO is an important second messenger...so it by blocking NO. NO works mainly through activation of its target receptor, the enzyme soluble guanylate cyclase, which, when activated, produces the second messenger cyclic-guanosine monophosphate (cGMP).
ReplyDeleteA strong case for anti-inflammatory effects of NO is provided by studies showing that pharmacological inhibition of NO or genetic deletion of its synthases elevates leukocyte-endothelial cell interaction in diverse organs and tissue.
Early investigations using human umbilical vein endothelial cells suggested that NO regulates leukocyte recruitment by modulating adhesion molecule expression on endothelial cells although more recent studies refute this showing only minimal effects on microvascular endothelial cell adhesion molecule expression in vitro and in vivo. This suggests that regulation of adhesion by NO may involve direct effects on leukocytes.
