Overnight starved Jurkat cells were treated with or without IFN-α for 24 hours, then fixed and permeabilized with FOXP3 Fix/Perm Buffer Set. Cells were then stained with IRF7 (clone 12G9A36) Alexa Fluor® 488 (solid line with open histogram for untreated cells, filled histogram for stimulated cells) or mouse IgG2b, κ Alexa Fluor® 488 isotype control (dashed line for unstimulated, dotted line for stimulated).

Description

IRF-7 is a member of the interferon regulatory transcription factor family that plays key regulatory roles in innate immunity. Upon virus infection, IRF-7 forms a complex with MyD88 and TRAF6 when stimulated by toll-like receptors TLR7, TLR8, and TLR9, which in turn results in nuclear translocation and induction of interferon gene expression. IRF-7 gene expression is upregulated by the stimulation of interferon through the Jak-STAT signaling pathway, which forms a positive feedback loop. The protein level of IRF-7 after activation is then downregulated by the ubiquitin-proteasome system to avoid excessive production of interferons that may cause damage to the host. Virus induced type I interferon expression was completely abrogated in IRF-7 knockout mice, suggesting that IRF-7 is critical for interferon mediated host defense during virus infection.
