IFNG and COVID-19: Conversely, Trajectory 4 captured late T1/alarmin‐driven inflammatory processes utilized by COVID‐19, demonstrating significantly increased IFNγ (log2FC 0.287, FDR adjusted p = 2.6e‐03) and IL‐33 responses (log2FC 0.218, FDR adjusted p = 4.6e‐03) compared to healthy MCs in late pseudotime phases (Figure S13B).
