To determine if the IFN-γ signaling, discovered CXCL9/10/11–containing cytokine cassette, cytotoxic lymphocytes, TRAIL, BAFF, and endogenous DAMP expression are replicable features of lung pathology in critical COVID-19, we investigated the expression of the relevant genes in available community data sets. Here, CXCL9 is linked to COVID-19.
