IFNG and infection: While delayed or impaired type I IFN signaling has been implicated in severe COVID‐19 infection, the role of the type II IFN signaling pathway is less clear with published findings showing mildly increased IFN‐γ levels in the serum and bronchoalveolar lavage fluid of patients with non‐severe infection but not in those with severe disease (Jamilloux et al., 2020; Lagunas‐Rangel & Chavez‐Valencia, 2020).
