Glucocorticoid-induced leucine zipper (GILZ) controls inflammation and tissue damage after spinal cord injury

Spinal cord injury (SCI) occurs following damage to the spinal column. Following trauma, tissue damage is further exacerbated by a secondary damage due to a SCI-activated inflammatory process. Control of leukocytes activity is essential to therapeutic inhibition of the spinal cord damage to ameliorate the patient's conditions. The mechanisms that regulate neuroinflammation following SCI, including T-cell infiltration, have not been completely clarified. Glucocorticoids (GC) are antiinflammatory drugs widely used in therapy, including treatment of SCI. GC efficacy may be linked to many molecular mechanisms that are involved in regulation of leukocytes migration, activation, and differentiation. We have previously shown that the antiinflammatory activity of GC is in part mediated by glucocorticoid-induced leucine zipper (GILZ). Here, we investigated the role of GILZ in inflammation and spinal cord tissue damage following a spinal trauma.
