Progress on interleukin-27 in tumor immunity / 浙江大学学报·医学版

ABSTRACT

As a member of IL-6/IL-12 cytokine family, IL-27 is a heterodimeric cytokine composed of the p28 and EBI3. Functioning as a linkage between innate and adaptive immunity, IL-27 is mainly produced by activated antigen-presenting cells and has a variety of responder cells including T cells, NK cells, macrophages and dendritic cells. IL-27 plays an antitumor role through promoting the production of cytotoxic T cells, regulating the differentiation of T cell subsets, enhancing the function of NK cells and inhibiting the angiogenesis. On the other hand, IL-27 may also have a positive effect on tumor progress and metastasis. IL-27 can be used as a reference marker for tumor diagnosis, due to its relation to the occurrence and development of tumors. This article reviews the research progress on the roles of IL-27 in tumor biological regulation.
