Granular juxtaglomerular cell hyperplasia caused by cyclosporine
Abstract:
Histologic study of kidneys from rabbits given cyclosporine (CsA) revealed a marked hyperplasia of granular cells in the juxtaglomerular (JG) apparatus, but without a significant increase in the total cell number of JG cells. The increase in granular JG cells as compared with the control group was 204% and 406% for 30 mg/kg alternate days and 30 mg/kg daily groups, respectively. The increases for the lower-dosage groups were much smaller, although the increases were statistically significant for all but the 10 mg/kg alternate-days group. Other studies suggest that sympathomimetic activity of CsA may be the mechanism involved in granular JG cell hyperplasia.

Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous capillaries...
Renal Drug Excretion: Glomerular Filtration
