Tolerogenic Mechanisms in Liver Transplantation
incidence of rejection compared with other solid organs, and spontaneous acceptance of the liver graft with successful discontinuation of immunosuppression has been reported in nearly 20% of LT recipients [10,11]. Multiple studies have suggested the protective effect of the liver allograft in Simultaneous Liver-Kidney Transplantation (SLKT) compared with recipients of isolated renal transplants...
متن کاملModulation of T cell responses by IL-2 and IL-2 complexes.
Interleukin-2 (IL-2) is a cytokine centrally involved in the regulation of immune tolerance and activation by its effects on CD4+ T regulatory (Treg) cells and cytotoxic effector lymphocytes, respectively. Due to these properties IL-2 immunotherapy has been used, as low-dose IL-2, in the treatment of autoimmune and chronic-inflammatory disorders; conversely, at high doses, IL-2 has shown effica...
متن کاملBone marrow dendritic cells deficient for CD40 and IL-23p19 are tolerogenic in vitro
Objective(s): In addition to pro-inflammatory role, dendritic cells (DCs) can also be anti-inflammatory when they acquire tolerogenic phenotype. In this study we tested the role of CD40 and IL-23p19 in antigen presenting function of bone marrow-derived DCs (BMDCs) by comparing BMDCs derived from CD40 knockout (CD40KO-DCs) and IL-23p19 (IL-23p19KO-DCs) knockout mice wit...
متن کاملDietary fatty acid modulation of mucosally-induced tolerogenic immune responses.
Immunological unresponsiveness or hyporesponsiveness (tolerance) can be induced by feeding protein antigens to naive animals. Using a classical oral ovalbumin gut-induced tolerance protocol in BALB/c mice we investigated the effects of dietary n-6 and n-3 polyunsaturated fatty acids (PUFA) on high-and low-dose oral tolerance (and in non-tolerised animals, i.e. effects of antigen challenge alone...
متن کاملHuman placenta-derived adherent cells induce tolerogenic immune responses
Human placenta-derived adherent cells (PDAC cells) are a culture expanded, undifferentiated mesenchymal-like population derived from full-term placental tissue, with immunomodulatory and anti-inflammatory properties. PDA-001 (cenplacel-L), an intravenous formulation of PDAC cells, is in clinical development for the treatment of autoimmune and inflammatory diseases. To elucidate the mechanisms u...
