Abstract

Autoimmune hepatitis (AIH) is a progressive, life-threatening liver disease that remains treated largely with broad immunosuppression. In this issue of Cell Stem Cell, Jing and colleagues reprogram follicular helper T (Tfh) cells in vivo into antigen-specific FOXP3⁺ CAR-Tfh cells to restore immune tolerance by rewiring core drivers of autoimmunity.
