How TZIELD Works

Teplizumab-mzwv binds to CD3, a cell surface antigen found on T lymphocytes. This binding may involve partial agonistic signaling and the deactivation of autoreactive T lymphocytes that target pancreatic beta cells. The drug also increases the proportion of regulatory T cells and exhausted CD8+ T cells in the peripheral blood. These actions collectively work to delay the clinical onset of Stage 3 type 1 diabetes.
