IFI44L and infection: Curiously, we did identify several highly downregulated genes in AgerAHA/AHA neutrophils that were not found in Ager−/− neutrophils, including Gbp2b, Ifi44, and Ifi44l (Figure 5D and Figure 5—figure supplement 3A-C), all of which have been shown to be interferon γ-induced genes and play important roles in defense against infection (Santos and Broz, 2018; Kim et al., 2011; Busse et al., 2020).
