- STAT1
STAT1 is a member of the Signal Transducers and Activators of Transcription family of transcription factors. STAT1 is involved in upregulating genes due to a signal by either type I or type II
interferons . In response to IFN-γ stimulation, STAT1 forms homodimers or heterodimers withSTAT3 that bind to the GAS (Interferon-Gamma Activated Sequence) promoter element; in response to either IFN-α or IFN-β stimulation, STAT1 forms a heterodimer withSTAT2 that can bind the ISRE (Interferon Stimulated Response Element) promoter element.

Katze, Yupeng He & Michael Gale, "et al" |title=Viruses and interferon: a fight for supremacy. |journal=Nature Reviews Immunology |volume=2 |number=9 |pages=675–87 |year=2002 |pmid=12209136 |doi=10.1038/nri888] In either case, binding of the promoter element leads to an increased expression of ISG (Interferon Stimulated Genes).Expression of STAT1 can be induced with
diallyl disulfide , a compound in garlic.
