Abstract
Systemic fibrosis can be induced in humans with gadolinium-based contrast, and cumulative doses correlate with severity. Bone marrow-derived fibrocytes accumulate in the dermis.Whether target organs liberate chemokines to recruit these fibrocytes or whether fibrocytes are stimulated to home to the affected tissue is unknown. Transgenic (tagged) donor rats were treated with gadolinium-based contrast. Bone marrow was obtained from diseased animals and age-matched controls. Rats with subtotal nephrectomies were lethally irradiated and underwent salvage transplantation with either the contrast-näýve or contrast-exposed bone marrow. Groups were randomly assigned to control or contrast treatment. Contrast treatment led to dermal fibrosis, and this was exacerbated in recipients of contrast-exposed marrow. Fibronectin, C-C chemokine receptors (CCRs)2 and 7, and oxidative stress were all increased in skin from contrast-treated animals-all parameters more severe in recipients of contrast-treated animals. The respective ligands, monocyte chemoattractant protein and C-C motif ligand 19, were both elevated in skin from contrast-treated animals. Coadministration of gadolinium-based contrast and a CCR2 inhibitor reduced the severity of skin disease as well as dermal cellularity. The functional role of chemokines in the effects of gadolinium-based contrast was further confirmed in in situ coculture studies using neutralizing CCR2 antibodies. These data implicate dermal liberation of specific chemokines in the recruitment of circulating bone marrow-derivedcells.Thedisease isaugmentedbybonemarrowexposure to contrast,whichexplainswhymultiple exposures correlate with severity.-Drel, V.
