When combined with arachidonic acid, IFN‐γ induces pronounced ferroptosis in various tumor cell lines.[20a] The inhibition of toll‐like receptor 4 (TLR4) by a TLR4 inhibitor ameliorates ferroptosis in the hypoxic‐ischemic injury of hippocampal neurons.[17a] IRF7 belongs to the transcription factors family of IRFs. The gene discussed is TLR4; the disease is neoplasm.
