a mRNA expression of human CCL2 (hCCL2) versus murine Ccl2 (mCCL2) in murine lungs. Human CCL2 is only expressed in transgenic mice, but not in controls. The murine (endogenous) Ccl2 was expressed in both transgenic and nontransgenic animals. Log scale (y-axis). b Transgenic animals expressing hCCL2 divided into those with and without OP manifestation
