ABSTRACT
The interferons(IFNs) are a family of the multifunctional cytokines, which are a kind of highly active and multifunctional glycoproteins.Studies in recent years have shown that IFNs exert a powerful antitumor effect by regulating the proliferation of tumor cells, suppressing tumor metastasis and angiogenesis, and activating antitumor immune response.Combined with other tumor treatment methods, it can inhibit the development of a variety of blood system tumors and solid tumors.In addition, the use of IFNs inducers or IFNs combined with emerging immunotherapy can significantly increase the effectiveness of tumor therapy.This review focuses on our understanding of antitumor mechanism and clinical application of IFNs, and provides some guidance for future research and clinical treatment.
