Liver X receptor alpha (LXRalpha) and LXRbeta are members of the nuclear receptor superfamily of ligand-activated transcription factors. The aim of this study was to investigate the effects of T0901317, a potent LXR receptor ligand, in a mouse model of spinal cord injury (SCI). SCI was induced by the application of vascular clips (force of 24 g) to the dura via a four-level T5-T8 laminectomy in mice. Treatment with T0901317, 1 and 6 h after the SCI, significantly decreased (i) the degree of spinal cord inflammation and tissue injury (histological score); (ii) neutrophil infiltration (myeloperoxidase activity); (iii) inducible nitric oxide synthase expression; (iv) nitrotyrosine, lipid peroxidation, and poly-ADP-ribose formation; (v) pro-inflammatory cytokines expression; (vi) nuclear factor-kappa B activation; and (vii) apoptosis (terminal deoxynucleotidyltransferase-mediated UTP end labeling staining, FAS ligand, Bax, and Bcl-2 expression). Moreover, T0901317 significantly ameliorated the loss of limb function (evaluated by motor recovery score). These data suggest that LXR ligand may be useful in the treatment of inflammation associated with SCI.
