Mechanism of action

Basiliximab binds specifically to the alpha chain (CD25) of the IL-2 receptor on activated T lymphocytes, blocking IL-2-mediated T cell proliferation. This prevents the clonal expansion of T cells that would otherwise drive allograft rejection. By selectively targeting activated T cells during the critical early phase of immune response, it reduces acute rejection without broadly suppressing all immune function.
