The interleukin (IL)-6/IL-12 family cytokines have pleiotropic functions and play
critical roles in multiple immune responses. This cytokine family has very unique
characteristics in that they comprise two distinct subunits forming a heterodimer
and each cytokine and receptor subunit shares with each other. The members of
this cytokine family are increasing; currently, there are more than six
cytokines, including the tentatively named cytokines IL-Y (p28/p40), IL-12
(p35/p40), IL-23 (p19/p40), IL-27 [p28/Epstein-Barr virus-induced protein 3
(EBI3)], IL-35 (p35/EBI3), and IL-39 (p19/EBI3). This family of cytokines covers
a very broad range of immune responses, including pro-inflammatory responses,
such as helper T (Th)1, Th2, and Th17, to anti-inflammatory responses, such as
regulatory T (Treg) cells and IL-10-producing Treg cells. IL-12 is the first
member of this family, and IL-12, IL-23, and IL-27 are mainly produced by
activated antigen-presenting cells, such as dendritic cells and macrophages.
IL-12 plays a critical role in the promotion of Th1 immune responses by inducing
interferon-? production to combat pathogens and malignant tumors. IL-23 induces
IL-17 production and is necessary to maintain pathogenic Th17 cells that cause
inflammatory and autoimmune diseases. IL-27 was initially reported to play a
critical role in promotion of Th1 differentiation; however, subsequent studies
revealed that IL-27 has broader stimulatory and inhibitory roles by inducing
IL-10-producing Treg cells. IL-35 is produced by forkhead box P3(+) Treg cells
and activated B cells and has immunosuppressive functions to maintain immune
tolerance. The most recently identified cytokine, IL-39, is produced by activated
B cells and has pro-inflammatory functions. The cytokine tentatively named IL-Y
seems to have anti-inflammatory functions by inhibiting Th1 and Th17
differentiation. In addition, individual cytokine subunits were also shown to
have self-standing activities. Thus, promiscuity within the IL-6/IL-12 family
cytokines complicates structural and functional clarification and assignment of
individual cytokines. A better understanding of the recent advances and expanding
diversity in molecular structures and functions of the IL-6/IL-12 family
cytokines could allow the creation of novel therapeutic strategies by using them
as tools and targeted molecules.
