IRF1 (Interferon Regulatory Factor 1) is a transcription factor encoded by the IRF1 gene located on chromosome 5q31.1. IRF1 is a key regulator of the interferon response and controls the expression of numerous genes involved in antiviral defense, immune regulation, and cell survival. [@irf]

In the brain, IRF1 plays complex roles in neurodegeneration, modulating [neuroinflammation](/mechanisms/neuroinflammation), [microglial activation](/cell-types/microglia), and neuronal survival pathways.[@irf] [@irfa]
The protein encoded by IRF1 is [IRF1 Protein](/proteins/irf1-protein).[@irfa] [@irfb]

Overview
IRF1 was the first identified member of the interferon regulatory factor family and serves as a master regulator of interferon-stimulated genes (ISGs). Unlike IRF2, which acts primarily as a repressor, IRF1 functions as a transcriptional activator. [@microglial]
The study of Irf1 Gene Interferon Regulatory Factor 1 has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
