Granular cells, also known as juxtaglomerular cells, are primarily involved in the regulation of blood pressure through the renin-angiotensin system, not directly in the regulation of glomerular filtration rate (GFR). They secrete renin in response to a decrease in blood pressure, which indirectly affects GFR, but they do not directly regulate the filtration process through contraction or other means like the other mechanisms listed.
