This is a mouse model available to study T-cell differentiation. Growth factor independent 1 (GFi-1) is a transcriptional repressor that is transiently induced during T-cell activation. This knockout mouse line is a GFi-1[flox/flox] introduced into a mouse Cre controlled by a CD4 promoter, which allows selective removal of GFi-1 exclusively in T-cells. It has thus-far been used to demonstrate that GFi-1 plays a critical role in enhancing Th2 cell expansion and repressing induction of Th17 and CD103+ iTreg cells.
