Popis: Long-term renal graft acceptance still requires long-term immunosuppressive therapy, which is accompanied by many adverse effects. Contrarily insufficient immunosuppression could lead to graft rejection and its failure. Therefore, research continues for biomarkers that reflect a patient's immunological status and thus allowing for individualized immunosuppressive therapy. In our study we showed lower incidence of acute rejection in kidney transplant recipients treated with rabbit anti-thymocyte globulin (rATG) or basiliximab induction within the first three months after transplantation. The rATG induction caused profound decrease of recipient's peripheral blood T and NK cells, as well as transcripts that are exclusively expressed by these cell types together with expansion of regulatory T cells (Tregs) among CD4+ T cells. In rATG group the increase of two transcripts associated with rejection (MAN1A1 and TLR5) was also observed in early post-transplant period. After the basiliximab induction we transiently detected CD4+CD25low/-FoxP3+ cell population along with disappearance of CD4+CD25+FoxP3+ Tregs. Basiliximab induction resulted in a transient increase in CD4+FoxP3+ Tregs, accompanied by the highest peripheral expression levels of markers associated with operational tolerance (FOXP3 and TCAIM)....
