WebJan 1, 2007 · Autoregulation of renal blood flow (RBF) is caused by the myogenic response (MR), tubuloglomerular feedback (TGF), and a third regulatory mechanism that is independent of TGF but slower than MR. The underlying cause of the third regulatory mechanism remains unclear; possibilities include ATP, ANG II, or a slow component of MR. Web(1) When initiated, both the myogenic response and the tubuloglomerular feedback adjust the afferent arteriole muscle tone.
