Abstract

Purpose: Tocilizumab, a monoclonal antibody directed against the IL-6 receptor, might block detrimental effects of IL-6 on transplantation. IL-6 plays a considerable role in cytokine storm after stem cell transplantation as well as graft versus host disease, and it has also been shown to be involved in solid organ allograft rejection; therefore, tocilizumab is expected to promote graft survival. Nonetheless, due to the small number of studies and disparate methods of drug administration and outcome evaluation, for which types of transplantation, at which stages, and to what extent tocilizumab could be applied remains to be defined. Methods: The Pubmed, SCOPUS and Google Scholar search engines were used to collect data. The keywords were determined by Pubmed MeSH. No time limitation was set and all types of articles were allowed. Results: According to the potential of Tocilozumab in controlling both cellular and humoral immunity it could be considered as a promising agent in tolerance induction; however, blocking IL-6 signaling might result in augmented infection rate in recipients. Conclusion: The need for providing effective and safe immunosuppressive agents to protect transplanted cells and organs against allo-reactivity urges the collection and discussion of all available findings about inhibition of determining immune components including cytokines; herein, we have summarized the clinical consequences of blocking IL-6 by tocilizumab in stem cell and solid organ transplantations. © 2020, Springer-Verlag GmbH Germany, part of Springer Nature.
