Background
Interleukin-27 (IL-27) is a heterodimeric cytokine that belongs to the IL-6/IL-12 family of long type I cytokines. It is composed of two subunits: EBI3 (EBV-induced gene 3), which is related to the p40 subunit of IL-12 and IL-23, and p28, which is related to the p35 chain of IL-12. IL-27 is primarily produced by monocytes, endothelial cells, and dendritic cells. It signals through a heterodimeric receptor complex composed of WSX-1 (TCCR) and gp130. IL-27 has both anti-inflammatory and pro-inflammatory properties. As an anti-inflammatory cytokine, it induces a general negative feedback program that limits T and NK-T cell activity. During the onset of infection, IL-27 induces an IL-12 receptor on naïve CD4+ T cells, making them susceptible to subsequent IL-12 activity and possible Th1 development.
