The transcription factor BATF pioneers the differentiation program of effector CD8

Summary: Imagine your body's immune system has an army of soldier cells called CD8 T cells. Before these cells can fight off invaders like viruses or cancer, they need a special key to unlock their fighting instructions. A protein called BATF acts exactly like this master key. It opens up the cell's instruction manual (DNA) so the cell can transform into a fully armed, active fighting machine. Without BATF, our immune soldiers wouldn't know how to attack!
