Interferon regulatory factor 7

IRF-7, Interferon Regulatory Factor-7
IRF7 encodes interferon regulatory factor 7, a member of the interferon regulatory transcription factor (IRF) family. IRF7 has been shown to play a role in the transcriptional activation of virus-inducible cellular genes, including interferon beta chain genes. Inducible expression of IRF7 is largely restricted to lymphoid tissue. Multiple IRF7 transcript variants have been identified, although the functional consequences of these have not yet been established. [provided by RefSeq, Jul 2008] (from NCBI)

Liao et al., San Francisco, United States. In J Eur Acad Dermatol Venereol, 23 Apr 2015
RESULTS: We observed significant overexpression of 16 antiviral genes in lesional psoriatic skin, with a greater than two-fold increase in ISG15, RSAD2, IRF7, MX2 and TRIM22 (P < 1E-07).
The histidine transporter SLC15A4 coordinates mTOR-dependent inflammatory responses and pathogenic antibody production.
Toyama-Sorimachi et al., Tokyo, Japan. In Immunity, Oct 2014
SLC15A4 loss disturbed the endolysosomal pH regulation and probably the v-ATPase integrity, and these changes were associated with disruption of the mTOR pathway, leading to failure of the IFN regulatory factor 7 (IRF7)-IFN-I regulatory circuit.

Duan et al., Beijing, China. In Bing Du Xue Bao, Sep 2014
Innate immune adaptors such as TRIF, MAVS, IRF3, IRF7 and NEMO have various potential cleavage sites in picornavirus 3Cpro (TRIF and NEMO show considerable diversity in their cleavage sites).
IRF5-mediated signaling and implications for SLE.
Jefferies et al., Dublin, Ireland. In Clin Immunol, Aug 2014
In addition to IRF3 and IRF7, the transcription factor IRF5 has been shown to be involved in type I IFN production and interestingly, polymorphisms of the IRF5 gene in humans can result in risk or protective haplotypes with regard to SLE susceptibility.
