TNF and nervous system disorder: Coronaviridae is an enveloped positive‐stranded, non‐segmented RNA virus with a genome of about 30 kb.[4]Coronaviridae viruses are responsible for cardiovascular, hepatic, respiratory, gastrointestinal, and neurological diseases, with major symptoms associated with a hyperbolic expression of proinflammatory signals and cytokines such as interleukins, interferon‐gamma (IFN‐γ), IFN‐γ induced protein 10 (IP‐10), macrophage inflammatory protein 1A and 1B (MIP‐1A, MIP1‐B), platelet‐derived growth factor (PDGF), tumor necrosis factor (TNF‐α), and vascular endothelial growth factor (VEGF).[5]
