Background:  IL-27 triggers expansion of antigen-specific naive CD4+ T cells and promotes polarization towards a Th1 phenotype with expression of γ-interferon. IL-27 contributes to the development of an adaptive immune response through its action on CD4+ T cells and also directly acts on cells of the innate immune system. IL-27 protein levels increase upon activation of antigen-presenting cells. IL-27 protein induces orphan cytokine receptor WSX-1/TCCR-dependent clonal expansion of naive but not memory CD4+ T cells. IL-27 signaling through TCCR/WSX-1 induces phosphorylation of Stat1-5. The predicted 243 amino acid human IL-27 protein, which is 73% identical to the mouse protein, contains an N-terminal signal peptide, several O-glycosylation sites and a stretch of 13 glutamate residues between helices C and D.
