Class A1 scavenger receptors in cardiovascular diseases.

abstract：BACKGROUND AND PURPOSE:Normal pregnancy is associated with decreased vascular resistance and increased release of vasodilators. Endothelin-1 (ET-1) causes vasoconstriction via endothelin receptor type A (ET(A)R), but could activate ET(B)R in the endothelium and release vasodilator substances. However, the roles of ET(B...
