what type of response by the afferent arterioles
In summary, thapsigargin treatment markedly attenuates juxtamedullary afferent arteriolar vasoconstrictor responses to Ang II or NE. In addition, depletion of intracellular calcium pools with thapsigargin completely abolishes the response of juxtamedullary efferent arterioles to these vasoconstrictor agents.hese studies were conducted to determine the role of calcium release from the thapsigargin-sensitive intracellular calcium pool on the Ang II-and NE-mediated vasoconstriction of juxtamedullary afferent and efferent arterioles.
