title: [Perspectives in clinical immunology].
abstract: Since the last years the better knowledge of immunologic mechanisms underlying autoimmune phenomena and rejection of allotransplants has been accompanied by an impressive production of new drugs: new inhibitors of purine and pyrimidine synthesis, as mycophenolate mofetil and leflunomide respectively, new inhibitors of calcineurin, such as tacrolimus, and target of rapamycine, such as sirolimus. Moreover, the tremendous advance in the methodology of producing monoclonal antibodies and the genetic engineering of proteins has led to a wide variety of biological agents, many of them have been approved as important new therapies for autoimmune diseases and against graft rejection. Monoclonal antibodies targeting IL-2 cytokine receptor have been shown to be useful in decrease the incidence of rejection. Moreover, monoclonal antibodies are available which target inflammatory cytokines, such as TNFalpha and IL-1, while other monoclonal antibodies may cause immune cell depletion, such as anti CD20 rituximab, or cause disruption of co-stimuli, like CTLA4Ig abatacept in the treatment of rheumatoid arthritis and anti CD11 efalizumab in the treatment of psoriasis. The new biologic agents have induced salutary clinical effects and extended the therapeutic option of patients not responding to existing treatments. The future looks brighter than ever as the recorded success fuels efforts to optimize the use of the biologic agents and extend their use in other diseases.
