Interferon regulatory factors: A key to tumour immunity.

Interferon regulatory factors (IRFs), which have 10 members, belong to the transcription factor family and were named because of the regulation of interferon expression. They play important roles in the immune regulation, cell differentiation, cell apoptosis, and cell cycle regulation. This article will review the functional characteristics and immune activity of the family members, especially in the role of cell differentiation and autoimmune diseases. Intensive studies will help uncover the pathogenesis of the disease in a more comprehensive view, and provide novel targets for disease treatment. But the most important problems yet to solve is IRFs function in the development processes of tumour, and whether IRFs can be an important regulator in tumour immune treatment.
