TNF and focal epilepsy: In conclusion, this MR study demonstrates that interleukin-5 and interleukin-1 receptor antagonists are potentially correlated factors with focal epilepsy etiology, while interleukin-10, interleukin-1β, interleukin-1Ra, interleukin-7, tumor necrosis factor-α, and interferon-γ possibly contribute to focal epilepsy development downstream.
