How IMULDOSA Works

IMULDOSA is a monoclonal antibody that binds specifically to the p40 protein subunit used by both the IL-12 and IL-23 cytokines. By targeting this subunit, the drug prevents these cytokines from interacting with the IL-12Rβ1 receptor chain found on the surface of immune cells. This disruption inhibits the signaling and cytokine cascades that lead to natural killer cell activation and T-cell differentiation. This mechanism addresses the chronic inflammation that characterizes immune-mediated diseases like Crohn’s disease and ulcerative colitis.
