cardiovascular system
• UTP- or UDP-treated aortic rings fail to exhibit an increase in contractile response unlike similarly treated wild-type aortic rings
|
• UDP-treated aortic rings exhibit impaired relaxation compared with similarly treated wild-type aortic rings
|
immune system
• macrophages do not exhibit an increase in inositol phosphate production upon UDP or UTP treatment unlike wild-type cells
• macrophages treated with LPS and UDP fail to exhibit increased MIP-2 and IL6 secretion unlike similarly treated wild-type cells
• however, macrophages exhibit normal response to 100 uM ATP
