Abstract

Previous studies have demonstrated that recipient‑derived immature dendritic cells transfected by recombinant adenovirus‑mediated IKK2dn (Adv‑IKK2dn) and loaded with donor splenocyte lysate generate CD4+CD25‑ T cells (Adv‑IKK2dn‑CD4+CD25‑ T cells). These cells may inhibit T cell responses in vitro. In the present study, Lewis (LW) rats were administered with an intravenous injection of naive CD4+ T cells, empty adenovirus (Adv‑0)‑dendritic cell‑generated CD4+CD25‑ T cells (Adv‑0‑CD4+CD25‑ T cells), Adv‑IKK2dn‑CD4+CD25‑ T cells or an equal volume of normal saline, seven days prior to transplantation. The potency and the mechanism of action of Adv‑IKK2dn‑CD4+CD25‑ T cells was analyzed, as well as an investigation of their tolerogenic properties in vivo. Administration of Adv‑IKK2dn‑CD4+CD25‑ T cells in vivo to LW rats was observed to markedly prolong the survival of a kidney allograft from Brown Norway rats. Furthermore, the Adv‑IKK2dn‑CD4+CD25‑ T cell‑treated group exhibited significantly reduced levels of interleukin (Il)‑2 and interferon‑γ production and increased Il‑10 and transforming growth factor‑β (TGF‑β) secretion. The serum creatinine levels remained at low levels in the Adv‑IKK2dn‑CD4+CD25‑ T cell‑treated group. Their ability to induce allogeneic T cell proliferation was markedly reduced compared with the other groups. These observations indicated that Adv‑IKK2dn‑CD4+CD25‑ T cells induce prolongation of kidney allograft survival in vivo, which is hypothesized to be due to the high expression levels of Il‑10 and TGF‑β.
