The vascular effects of endothelins (ET) are in mammals mediated via two receptor subtypes, endothelin A (ET(A), mainly constrictive) and endothelin B (ET(B), mainly dilating) receptors. We have examined the presence of ET(A) and ET(B) receptor mRNA using the reverse transcription polymerase chain reaction (RT-PCR) in both normal human cerebral arteries and(More)
Whereas the endothelin A receptor is generally believed to mediate vasoconstriction; the endothelin B receptor seems elusive; both dilative and constrictive responses have been reported. Using the in vitro arteriograph, a method allowing compartmentalized study of vessel segments, segments of rat middle cerebral artery were cannulated with micropipettes,(More)
