Although the RBF falls in response to AII, the fall in GFR is not of equal magnitude because AII maintains pressure within the glomerular capillary by causing greater vasoconstriction of the efferent than of the afferent arteriole.
dilating the afferent arteriole to increase renal blood flow.
constricting the afferent arteriole to increase intraglomerular pressure.
The afferent arterioles showed amorphous eosinophilic material effacing the media.
For patient 6, immunofluorescence microscopy revealed granular deposits of IgG, IgM, C1q, C3, and C4 in the glomeruli along the glomerular capillary loops and in afferent arterioles. Electron microscopy demonstrated numerous epimembranous and intramembranous electrondense deposits and small mesangial deposits.
In the kidneys, afferent arterioles involved by a lupus microangiopathy contained pyknotic nuclear material that stained prominently with the TUNEL technique.
Ischaemic nephron injury, caused by afferent arteriole constriction, develops in early stages of cyclosporine-induced nephropathy [6].
