Autoimmune disorders are a complicated and varied group of diseases arising from inappropriate immune responses. Recent studies have demonstrated that ongoing inflammatory and immune responses are associated with increased oxygen consumption, a process resulting in localized tissue hypoxia within inflammatory lesions (inflammatory hypoxia), in which hypoxia-inducible factor 1 (HIF-1), an oxygen-sensitive transcription factor that allows adaptation to hypoxia environments, has been shown to play an important function. HIF-1 is a regulator of angiogenesis and immune system. Besides, HIF-1-mediated metabolic shift and fibrosis may also play crucial roles in some autoimmune disorders. Firstly, we briefly summarize the role of HIF-1 in angiogenesis, immune responses and fibrosis. Secondly, we will show the major recent findings demonstrating a role for HIF-1 signaling in autoimmune disorders, including rheumatoid arthritis, inflammatory bowel disease, psoriasis, systemic sclerosis and multiple sclerosis. The growing evidences may prompt HIF-1 to be a new target for treatment of autoimmune diseases. (C) 2016 Elsevier Inc. All rights reserved.
