Elevated concentrations of interleukin-6 (IL-6), interferon-gamma (IFN-γ), and interleukin-17A (IL-17A) have been observed in the plasma during the interictal phase of epilepsy, whereas IL-1β, TNF-α, and IL-10 did not rise in comparison to a healthy group [130]. The gene discussed is IFNG; the disease is epilepsy.
