Thank you for the opportunity to help you with your question!
Autoregulation and hormonal regulation do affect glomerular filtrate rate.
Renal autoregulation involves feedback mechanisms intrinsic to the kidney that cause either dilation or constriction in the afferent arteriole so as to counteract blood pressure changes and keep a steady GFR.
the hormone atrial natriuretic peptide (ANP) is a factor that can increase GFR.
Please let me know if you need any clarification. I'm always happy to answer your questions.
