Neuroinflammation is an inflammatory response which is induced by disease, stress, infection, or damage and mediated by cytokines such as Tumor Necrosis Factor alpha (TNFα), Interleukin (IL)-6, IL-1β, Interferon (IFN)γ and IL-8, chemokines, ROS, and secondary messengers [14,15,16]. The gene discussed is TNF; the disease is infection.
