AIM: To determine whether complement membrane attack complex (C5b-9) has a
pathogenic role in tubulointerstitial injury in a renal disease model
characterized by acute highly selective proteinuria. METHODS: Protein-overload
nephropathy (PON) was induced in adult female Piebald-Viral-Glaxo rats with or
without complement C6 deficiency (C6(-) and C6(+)) by daily intraperitoneal
injections of bovine serum albumin (BSA, 2 g/d), and examined on days 2, 4 and 8.
RESULTS: Groups with PON developed equivalent levels of heavy proteinuria within
24 h of BSA injection. In C6(+) rats with PON, the tubulointerstitial expression
of C5b-9 was increased and localized predominantly to the basolateral surface of
tubular epithelial cells (TECs), whereas it was undetectable in C6(-) animals.
TEC proliferation (as assessed by the number of BrdU+ cells) increased by more
than 50-fold in PON, peaking on day 2 and declining on days 4 to 8. There was a
trend for a reduction in the number of BrdU+ TECs on day 4 in the C6(-) PON group
(P = 0.10 compared to C6(+)) but not at any other time-point. Kidney enlargement,
TEC apoptosis (TUNEL(+) cells) and markers of tubular injury (tubule dilatation,
loss of TEC height, protein cast formation) were not altered by C6 deficiency in
PON. Interstitial monocyte (ED-1+ cell) accumulation was partially reduced in
C6(-) animals with PON on day 4 (P = 0.01) but there was no change in
myofibroblast accumulation. CONCLUSION: These data suggest that C5b-9 does not
mediate tubulointerstitial injury in acute glomerular diseases characterized by
selective proteinuria.
