Complement factor 5a (C5a) interaction with its receptor (C5aR1) contributes to
the pathogenesis of inflammatory diseases, including acute kidney injury.
However, its role in chronic inflammation, particularly in pathogen-associated
disorders, is largely unknown. Here we tested whether the development of chronic
inflammation and renal fibrosis is dependent on C5aR1 in a murine model of
chronic pyelonephritis. C5aR1-deficient (C5aR1-/-) mice showed a significant
reduction in bacterial load, tubule injury and tubulointerstitial fibrosis in the
kidneys following infection, compared with C5aR1-sufficient mice. This was
associated with reduced renal leukocyte infiltration specifically for
the population of Ly6Chi proinflammatory monocytes/macrophages and reduced
intrarenal gene expression of key proinflammatory and profibrogenic factors in
C5aR1-/- mice following infection. Antagonizing C5aR1 decreased renal bacterial
load, tissue inflammation and tubulointerstitial fibrosis. Ex vivo and in vitro
studies showed that under infection conditions, C5a/C5aR1 interaction upregulated
the production of proinflammatory and profibrogenic factors by renal tubular
epithelial cells and monocytes/macrophages, whereas the phagocytic function of
monocytes/macrophages was down-regulated. Thus, C5aR1-dependent bacterial
colonization of the tubular epithelium, C5a/C5aR1-mediated upregulation of local
inflammatory responses to uropathogenic E. coli and impairment of phagocytic
function of phagocytes contribute to persistent bacterial colonization of the
kidney, chronic renal inflammation and subsequent tubulointerstitial fibrosis.
