Modulation of chemokine CXCL12 and its receptor CXCR4 has been implicated in
attenuation of bleomycin (BLM)-induced pulmonary fibrosis and carbon
tetrachloride (CCl4)-induced hepatic injury. In pulmonary fibrosis, published
reports suggest that collagen production in the injured lung is derived from
fibrocytes recruited from the circulation in response to release of pulmonary
CXCL12. Conversely, in hepatic fibrosis, resident hepatic stellate cells (HSC),
the key cell type in progression of fibrosis, upregulate CXCR4 expression in
response to activation. Further, CXCL12 induces HSC proliferation and subsequent
production of collagen I. In the current study, we evaluated AMD070, an orally
bioavailable inhibitor of CXCL12/CXCR4 in alleviating BLM-induced pulmonary and
CCl4-induced hepatic fibrosis in mice. Similar to other CXCR4 antagonists,
treatment with AMD070 significantly increased leukocyte mobilization. However, in
these two models of fibrosis, AMD070 had a negligible impact on extracellular
matrix deposition. Interestingly, our results indicated that CXCL12/CXCR4
signaling has a role in improving mortality associated with BLM induced pulmonary
injury, likely through dampening an early inflammatory response and/or vascular
leakage. Together, these findings indicate that the CXCL12-CXCR4 signaling axis
is not an effective target for reducing fibrosis.
