    Transplant Tolerance: New Insights and Strategies for Long-Term Allograft Acceptance by Paulina Ruiz, Paula Maldonado, Yessia Hidalgo, Alejandra Gleisner, Daniela Sauma, Cinthia Silva, Juan Jose Saez, Sarah Nuñez, Mario Rosemblatt, Maria Rosa Bono

    Published 2013-01-01
    “…Despite the potential of organ transplantation, the administration of immunosuppressive drugs required for allograft acceptance induces severe immunosuppression in transplanted patients, which leads to serious side effects such as infection with opportunistic pathogens and the occurrence of neoplasias, in addition to the known intrinsic toxicity of these drugs. To solve this setback in allotransplantation, researchers have focused on manipulating the immune response in order to create a state of tolerance rather than unspecific immunosuppression. …”
