Updated project metadata. The cornerstone of mammalian intrinsic and innate immune defense against pathogens is the production of interferons (IFN), cytokines that stimulate anti-pathogen signaling pathways through the simultaneous expression of hundreds of interferon-stimulated genes (ISG). We compared the effects of IFN classes on the cellular proteome and relative restriction of virus progeny production across multiple physiologically relevant cell types and viruses. We integrated global proteome analyses with targeted mass spectrometry (MS), thermal proximity coaggregation-MS (TPCA-MS), and molecular virology assays to determine how ISGs differentially contribute to host antiviral capacities between immune-modulatory cell types. In differentiated macrophage-like monocytic cells, we classified sets of both shared and distinct ISG proteins responsive to each IFN class. We orthogonally confirmed the relative protein alterations using parallel reaction monitoring (PRM) by developing a proteotypic peptide library for ISG markers induced by each IFN class. Additional comparison to stimulation with pro-inflammatory LPS helped to contextualize the observed IFN signatures. We further assessed ISG protein interactions upon IFN types I and II stimulation, observing maintenance of key ISG protein complexes across treatments. Subsequent comparison of macrophage-like monocytic cells to primary keratinocytes enabled us to identify relative ISG abundances, cytokine induction, and antiviral capacities of both cell types across infections with several ubiquitous human viruses. Infections with herpes simplex virus-1 (HSV-1), adenovirus (AdV), and human cytomegalovirus (HCMV) revealed cell type-dependent differences in virus progeny production.
