Crescentic glomerulonephritis (Crgn) is a complex disorder where macrophage
activity and infiltration are significant effector causes. In previous linkage
studies using the uniquely susceptible Wistar Kyoto (WKY) rat strain, we have
identified multiple crescentic glomerulonephritis QTL (Crgn) and positionally
cloned genes underlying Crgn1 and Crgn2, which accounted for 40% of total
variance in glomerular inflammation. Here, we have generated a backcross (BC)
population (n = 166) where Crgn1 and Crgn2 were genetically fixed and found
significant linkage to glomerular crescents on chromosome 2 (Crgn8, LOD = 3.8).
Fine mapping analysis by integration with genome-wide expression QTLs (eQTLs)
from the same BC population identified ceruloplasmin (Cp) as a positional eQTL in
macrophages but not in serum. Liquid chromatography-tandem mass spectrometry
confirmed Cp as a protein QTL in rat macrophages. WKY macrophages overexpress Cp
and its downregulation by RNA interference decreases markers of glomerular
proinflammatory macrophage activation. Similarly, short incubation with Cp
results in a strain-dependent macrophage polarization in the rat. These results
suggest that genetically determined Cp levels can alter susceptibility to Crgn
through macrophage function and propose a new role for Cp in early macrophage
activation.
