Wong, Norman L. M., Bonita P. H. Wong, and Joseph K. C. Tsui. Vasopressin regulates endothelin-B receptor in rat inner medullary collecting duct. Am. J. Physiol. Renal Physiol. 278: F369–F374, 2000.—Previous studies have shown that endothelin (ET) antagonizes the actions of arginine vasopressin (AVP) in the renal collecting ducts. On the other hand, the effects of AVP on ET function within the ...

Ibe, Basil O., Fred C. Sander, and J. Usha Raj. Platelet-activating factor receptors in lamb lungs are downregulated immediately after birth. Am J Physiol Heart Circ Physiol 278: H1168–H1176, 2000.—Platelet-activating factor (PAF) is a phospholipid with diverse biological functions mediated by a G protein-coupled receptor.
