IFIT1, also known as P56 or ISG56, is a human antiviral protein induced by interferon that recognizes viral RNA lacking host-specific 5′ modifications and blocks its translation.
IFITM3
IFITM3 (interferon-induced transmembrane protein 3, 1-8U) is a 133 amino acid type II transmembrane restriction factor on chromosome 11 that blocks viral membrane fusion in endosomes, limiting influenza, dengue, Ebola, and SARS-CoV-2 entry.

IFNA2
IFNA2 (interferon alpha 2, Gene ID 3440) is a single-exon human gene at 9p21.3 encoding IFN-α2, the prototypic type I interferon; recombinant IFNα2a/2b (Roferon-A, Intron A) treat leukemia and viral hepatitis.
IFNAR1
IFNAR1 (interferon alpha/beta receptor 1, UniProt P17181) is the low-affinity subunit of the human type I interferon receptor with IFNAR2, signaling via TYK2/JAK1-STAT; targeted by anifrolumab for lupus.
IFNAR2
IFNAR2 (interferon alpha and beta receptor subunit 2, gene ID 3455, 21q22.11) encodes the primary ligand-binding chain of the human type I interferon receptor with IFNAR1, signaling via JAK1-STAT; mutations cause Immunodeficiency 45.
IFNB1
IFNB1 (interferon beta 1, IFN-beta, fibroblast interferon) is the single intronless human gene on chromosome 9p21.3 encoding type I interferon beta, which signals via IFNAR1/IFNAR2 Jak-STAT and whose recombinant products were the first MS disease-modifying therapies.
IFNfreeCOG trial
IFNfreeCOG (NCT02469012), a German trial of neurocognitive performance and emotional state in chronic hepatitis C patients on interferon-free sofosbuvir-based therapy, run by University of Wuerzburg at Burghausen with TAP, SF-36, HADS, and FIS-D measures.
IFNGR1
IFNGR1 (interferon gamma receptor 1), chromosome 6q23.3, encodes the ligand-binding chain of the IFN-γ receptor; mutations cause Mendelian susceptibility to mycobacterial disease, autosomal recessive or dominant.
Ifni War
The Ifni War, which Spanish historians call the Forgotten War, was fought from late 1957 to mid-1958 between Spain and Moroccan irregular forces over the enclave of Ifni.
IFNL3
IFNL3 (formerly IL28B) is a human gene on chromosome 19q13.2 encoding interferon-lambda 3, a type III interferon. Variants near it, notably rs12979860 and rs8099917, strongly predict hepatitis C clearance and interferon-based treatment response.
IFNL4
IFNL4 (interferon lambda 4 gene, chromosome 19q13.13) encodes IFN-λ4, a type III interferon produced only in carriers of the ΔG allele of rs368234815; discovered 2013, it impairs hepatitis C virus clearance, unlike the protective TT frameshift allele.
