Background: The aim of this study was to evaluate the therapeutic efficiency of Anakinra, an IL-1ß antagonist with anti-inflammatory effects, in an experimental model of traumatic brain injury (TBI).
Methods: Fifty-four rats underwent TBI after a weighted object was dropped onto a metal disc secured to their skulls. Animals were randomized into 3 main groups: control (n=18), TBI + saline (n=18; six animals per time-point) with samples obtained at the first, sixth and twenty-fourth h postoperatively, and TBI + Anakinra (n=18; six animals per time-point) with brain samples obtained at the first, sixth and twenty-fourth h postoperatively.
