IL-18BP decreased GDF15 and increased citrulline levels in mouse serum after TBI. Mice received single dose of rhIL-18BP (2 mg/kg) or vehicle-control SC injection 48 h post-sham (0 Gy) or 9.4 Gy TBI and sera were collected on day 3, 4 and 7 after TBI. Levels of (a) GDF15 and (b) citrulline in mouse serum were measured with ELISA and Colorimetric kit. Results were obtained from two independent experiments (6 mice/group/experiment, N = 12). Means ± SD. Level of increase *p < 0.05; **p < 0.01; rhIL-18BP-treated vs. vehicle-treated.
