STING1 and infection: Infection of porcine alveolar macrophages with NH/P68 results in (i) the induction of significant levels of IFN-β, (ii) phosphorylation of STING, (iii) traffic of STING through the Golgi to perinuclear punctuated structures, and (iv) localization of IRF3 to the nuclear soluble fraction and binding to chromatin.
