Fli-1, a Functional Factor Performed in Autoimmune Lupus.

Systemic lupus erythematosus (SLE) is an autoimmune disease. The friend leukemia insertion site 1 (Fli-1) belongs to the Ets family of transcription factors. Recent findings suggested that expression of Fli-1 was abnormal in SLE patients and lupus mice. In addition, functional analysis indicated that Fli-1 plays a key role in the development of this complex autoimmune disorder. Here, we review the updated evidence indicating the roles of Fli-1 in autoimmune lupus. Hopefully, the information obtained may result in a better understanding of the pathogenesis of the systemic autoimmune disease.
