Turning the Thymus into an Engine of Immune Tolerance in T1D and Beyond

Type 1 diabetes is still a disease we manage day‑to‑day rather than prevent, and today’s approaches do little to stop the immune system from attacking beta cells in the first place. Zag Bio is trying to change that by turning the thymus, the body’s training ground for T cells, into a therapeutic engine for immune tolerance, using thymus‑homing antibodies to program long‑lived, antigen‑specific Tregs against type 1 diabetes and other autoimmune diseases. Zag Bio CEO Jason Cole discusses type 1 diabetes, how the company’s thymic training platform fits into the emerging tolerance landscape alongside cell therapies and nanoparticle approaches, and the potential to extend this strategy to a broader set of autoimmune diseases.
