Core Tip
Core tip: The liver not only protects itself from host alloimmune responses, but also modulates alloimmune responses to other simultaneously transplanted solid organs like heart or kidney. The titer of donor specific alloantibodies decreases after liver transplantation, making transplantation of other solid organs possible even in highly sensitized high-risk patients. The immune cells from the liver allograft cross-talk with recipient immune cells and modulate the immune system towards tolerance. The cross-talk between these cells suppress the genes involved in alloimmunity and upregulate the genes involved in tissue repair and metabolism.
