The Dark Side of IFN-?: Its Role in Promoting Cancer Immunoevasion.


ABSTRACT: Interferon-? (IFN-?) is a pleiotropic cytokine that has long been praised as an important effector molecule of anti-tumor immunity, capable of suppressing tumor growth through various mechanisms. On the contrary to such a bright side of IFN-?, it has also been involved in promoting an outgrowth of tumor cells with immunoevasive phenotype suggesting an existence of a dark "tumor-promoting" side effect of IFN-?. In this review, we will summarize this multi-functional role of IFN-? in tumor context, how it promotes changes in tumor phenotype towards increased fitness for growth in immunocompetent host. Furthermore, we summarize how IFN-? is involved in homeostatic or cancer-triggered mechanisms to establish an immunosuppressive tumor microenvironment.
