Degrandiet al. confirmed thatin vitro stimulation with poly(I:C) and LPS does not upregulate Gbp2b transcripts in C57BL/6J-derived ANA-1 macrophages, yet the study detected induced Gbp2b transcripts followingin vitro stimulation with IFNγ (Degrandiet al., 2007).In vivo, the induction of Gbp2b was also observed, both at a transcript and protein level, in C57BL/6J mice following infection withL. This evidence concerns the gene IFNG and infection.
