SOAT1 and STING-associated vasculopathy with onset in infancy: Indeed, because JAK-STAT inhibitors showed a similar suppressive effect on over-functional STING-induced immune responses, we hypothesize that STAT1 (downstream of STING-IRF3-type I IFN axis), which is constitutively phosphorylated in B and T cells of certain SAVI patients, may act as another potential target, but requires further investigation for the antagonistic binding of HHMX, in addition to TBK1 (19).
