Tacgraf (1mg) 30 Capsules

Tacrolimus, the active ingredient in Tacrolimus Capsules, exerts its immunosuppressive effects primarily by inhibiting the production and activation of T lymphocytes. It selectively binds to the intracellular protein, FK-binding protein 12 (FKBP12), creating a complex that then inhibits calcineurin, a calcium-dependent phosphatase enzyme. This inhibition prevents the dephosphorylation of the transcription factor NF-AT (nuclear factor of activated T-cells), which is essential for the transcription of several genes involved in T-cell activation, such as interleukin-2 (IL-2). By blocking the signal transduction pathway at the level of calcineurin, Tacrolimus suppresses the production of IL-2 and other cytokines, thereby inhibiting T-cell activation and proliferation. This mechanism is crucial in preventing the rejection of transplanted organs by modulating the immune response.

Immunosuppressant.
