Subduing the rebellion: Unmasking rogue cells in the immune system

Okinawa Institute of Science and Technology researchers identified JunB as a key target to selectively disable toxic T Helper 17 cells, reducing the risk of auto-immune diseases. By inhibiting JunB, these cells can still accumulate in the gut and respond to infections without turning rogue.
