This article discusses the need to implement effective methods for monitoring immune status and rehabilitation of patients after kidney transplantation. Induction of immunological tolerance which allows minimizing or even completely canceling supportive immunosuppressive therapy is one of the key tasks in the field of organ transplantation. Regulatory T-cells (TREGs) play an important role in maintaining immunological homeostasis, including limiting kidney transplant rejection, and potentially contribute to the development of immunological tolerance. At the same time, for the introduction of TREG therapy into clinical practice, it is necessary to overcome a number of unsolved problems, such as induction and cultivation of a sufficient number of TREG cells for therapeutic action as well as reducing the risks associated with TREG conversion to effector lymphocytes or an undesirable non-specific immunosuppressive effect. This review examines both the impact of common post-transplant pharmacological immunosuppression approaches on TREGs and the therapeutic potential of TREG cell cultures in prevention of kidney transplant rejection. The questions of ex vivo TREG manufacturing process and possible threats of applying cell technologies in this branch of transplantology were considered.
