Concerning composite tissue allotransplantation, which of the following is true?
A. Corticosteroids are used for both maintenance therapy and treatment of acute rejection episodes and act by inhibiting NF-kB activation and inflammatory cytokine productionAll of the above. The ultimate goal, and thus the focus of transplant immunology research, is to effectively suppress rejection while minimising toxic side effects. In clinical practice this is achieved through a balance of multiple drugs that interfere with the immune response at various sites by blocking the formation, stimulation, proliferation, and differentiation of lymphocytes. These drugs are administered immediately after transplanting the organ or tissues (induction therapy) and regularly thereafter ‘for life’ (maintenance therapy) and in response to rejection episodes (treatment or rescue therapy). The above drugs are often used following composite tissue allotransplantation.
