Zag Bio

Zag Bio has discovered a novel approach to create thymus-targeted medicines to treat and prevent autoimmune diseases by restoring central immune tolerance. Zag Bio designs bifunctional antibodies that deliver self-antigens to antigen-presenting cells in the thymus to harness the body’s natural process for training immune cells to recognize and tolerate self, halting or preventing autoimmune attacks on the body’s own tissues.
