IFN-γ concentration increases in the ipsilateral cortex four and 12 hours following a controlled cortical impact. Within four hours of a brain injury, IFN-γ increases (p < 0.05) in the ipsilateral cortex in comparison to both control and contralateral tissue. At all time points, IFN-γ was below detectable limits (BDL) in both the control and contralateral tissue. Within 24 hours of the injury, IFNγ concentrations returned to below detectable limits. All values are mean ± SEM, n = 5. Since IFNγ in both control and contralateral tissue were below detectable limits, no statistical analyses were performed.
