Angiogenin is upregulated during the alloreactive immune response and has no effect on the T-cell expansion phase, whereas it affects the contraction phase by inhibiting CD4+ T-cell apoptosis
(2016)Under growth conditions, angiogenin is translocated into the nucleus, where it enhances ribosomal RNA transcription, facilitating increased protein synthesis and cellular proliferation. During stress conditions, angiogenin ... -
A comparative analysis between proteasome and immunoproteasome inhibition in cellular and humoral alloimmunity
(2017)Triggered by the successful administration of the proteasome inhibitor bortezomib in kidney transplant recipients with acute or chronic antibody-mediated rejection, we evaluated the effect of the proteasome inhibitor ... -
Comparison of the effect of the aerobic glycolysis inhibitor dichloroacetate and of the krebs cycle inhibitor LW6 on cellular and humoral alloimmunity
(2017)Cell metabolism is altered during T-cell and B-cell activation and differentiation. Clarifying the exact metabolic shifts may lead to the development of new immunosuppressive medications. In this study, the effect of the ... -
Dichloroacetate at therapeutic concentration alters glucose metabolism and induces regulatory t-cell differentiation in alloreactive human lymphocytes
(2013)Background: Most cancer cells rely on aerobic glycolysis. Dichloroacetate (DCA) inhibits aerobic glycolysis and is a promising relatively nontoxic anticancer compound. However, rapidly proliferating effector T-cells also ... -
Differential effects of the two amino acid sensing systems, the GCN2 kinase and the mTOR complex 1, on primary human alloreactive CD4+ T-cells
(2016)Amino acid deprivation activates general control nonderepressible 2 (GCN2) kinase and inhibits mammalian target of rapamycin (mTOR), affecting the immune response. In this study, the effects of GCN2 kinase activation or ... -
In human alloreactive CD4+ T-cells, dichloroacetate inhibits aerobic glycolysis, induces apoptosis and favors differentiation towards the regulatory T-cell subset instead of effector T-cell subsets
(2016)Although kidney transplantation is the best therapy for end-stage renal disease, rejection remains a concern, and currently available immunosuppressive agents contribute to morbidity and mortality. Thus, novel immunosuppressive ... -
In human cell cultures, everolimus is inferior to tacrolimus in inhibiting cellular alloimmunity, but equally effective as regards humoral alloimmunity
(2017)Purpose: Acute cellular rejection is the major cause of immune-mediated graft failure early in the course of kidney transplantation, whereas chronic antibody-mediated rejection is a major contributor to graft loss in the ... -
In Mixed Lymphocyte Reaction, the Hypoxia-Inducible Factor Prolyl-Hydroxylase Inhibitor Roxadustat Suppresses Cellular and Humoral Alloimmunity
(2020)Hypoxia-inducible factor (HIF) prolyl-hydroxylase inhibitors are currently used for the treatment of renal anemia. Since HIF affects immune cells, we evaluated the effect of such a drug, the roxadustat, on adaptive immunity. ... -
Indoleamine 2, 3-dioxygenase Up-regulates Hypoxia-inducible Factor-1α Expression by degrading l-Tryptophan but not its activity in human alloreactive t-cells
(2018)Indoleamine 2, 3-dioxygenase (IDO) suppresses T-cell function at least in part by altering cell metabolism. Hypoxia-inducible factor-1 (HIF-1) increases upon T-cell activation and alters cell metabolism favoring their ... -
Indoleamine 2,3-dioxygenase depletes tryptophan, activates general control non-derepressible 2 kinase and down-regulates key enzymes involved in fatty acid synthesis in primary human CD4+ T cells
(2015)Indoleamine 2,3-dioxygenase (IDO) is expressed in antigen-presenting cells and exerts immunosuppressive effects on CD4+ T cells. One mechanism is through the inhibition of aerobic glycolysis. Another prerequisite for T-cell ... -
Indoleamine 2,3-dioxygenase downregulates T-cell receptor complex ζ-chain and c-Myc, and reduces proliferation, lactate dehydrogenase levels and mitochondrial glutaminase in human T-cells
(2016)Indoleamine 2,3-dioxygenase (IDO), through L-tryptophan depletion, activates general control non-derepressible (GCN) 2 kinase and suppresses T-cell proliferation, in addition to suppressing aerobic glycolysis and glutaminolysis, ... -
Indoleamine 2,3-dioxygenase suppresses humoral alloimmunity via pathways that different to those associated with its effects on T cells
(2019)Chronic antibody-mediated rejection remains a major cause of late graft loss. Regarding cellular alloimmunity, the immunosuppressive properties of indoleamine 2,3-dioxy-genase (IDO) have been well investigated; however, ... -
Indoleamine 2,3-dioxygenase, by degrading L-tryptophan, enhances carnitine palmitoyltransferase i activity and fatty acid oxidation, and exerts fatty acid-dependent effects in human alloreactive CD4+ T-cells
(2016)Indoleamine 2,3-dioxygenase (IDO) is expressed in antigen presenting cells and by degrading L-tryptophan along the kynurenine pathway suppresses CD4+ T-cell proliferation, induces apoptosis and promotes differentiation ... -

Uric acid increases cellular and humoral alloimmunity in primary human peripheral blood mononuclear cells
(2018)Aim: Hyperuricaemia is common among kidney transplant recipients and has been associated with worse graft outcome. Since episodes of acute cellular rejection and chronic humoral rejection contribute to decreased graft ...
