BACKGROUND & AIMS: Little is known about the pathogenic mechanisms of chronic
pancreatitis. We investigated the roles of complement component 5 (C5) in
pancreatic fibrogenesis in mice and patients. METHODS: Chronic pancreatitis was
induced by ligation of the midpancreatic duct, followed by a single supramaximal
intraperitoneal injection of cerulein, in C57Bl6 (control) and C5-deficient mice.
Some mice were given injections of 2 different antagonists of the receptor for
C5a over 21 days. In a separate model, mice were given injections of cerulein for
10 weeks to induce chronic pancreatitis. Direct effects of C5 were studied in
cultured primary cells. We performed genotype analysis for the single-nucleotide
polymorphisms rs 17611 and rs 2300929 in C5 in patients with pancreatitis and
healthy individuals (controls). Blood cells from 976 subjects were analyzed by
transcriptional profiling. RESULTS: During the initial phase of pancreatitis,
levels of pancreatic damage were similar between C5-deficient and control mice.
During later stages of pancreatitis, C5-deficient mice and mice given injections
of C5a-receptor antagonists developed significantly less pancreatic fibrosis than
control mice. Primary pancreatic stellate cells were activated in vitro by C5a.
There were no differences in the rs 2300929 SNP between subjects with or without
pancreatitis, but the minor allele rs17611 was associated with a significant
increase in levels of C5 in whole blood. CONCLUSIONS: In mice, loss of C5 or
injection of a C5a-receptor antagonist significantly reduced the level of
fibrosis of chronic pancreatitis, but this was not a consequence of milder
disease in early stages of pancreatitis. C5 might be a therapeutic target for
chronic pancreatitis.
