IFI30 is constitutively expressed in professional antigen-presenting cells (APCs), including B cells, dendritic cells and monocytes/macrophages, and induced by interferon-γ (IFN-γ) in other cell types, such as tumor cells (Arunachalam et al., 1998; Maric et al., 2001; Lackman et al., 2007; Nguyen et al., 2016).
