BackgroundIndividuals with rare kidney diseases account for 5–10% of people chronic disease, but constitute more than 25% patients receiving replacement therapy. The National Registry Rare Kidney Diseases (RaDaR) gathers longitudinal data from these conditions, which we used to study disease progression and outcomes death failure.MethodsPeople aged 0–96 years living 28 types were recruited 108 UK renal care facilities. primary cumulative incidence mortality failure in individuals diseases,...
The concept of regulatory T cell (Treg)-based immunotherapy has enormous potential for facilitating tolerance in autoimmunity and transplantation. Clinical translation Treg therapy requires production processes that satisfy the rigors Good Manufacturing Practice (GMP) standards. In this regard, we report our findings on implementation a robust GMP compliant process ex vivo expansion clinical grade Tregs, demonstrating feasibility developed manufacture final product application. This...
Short-term outcomes in kidney transplantation are marred by progressive transplant failure and mortality secondary to immunosuppression toxicity. Immune modulation with autologous polyclonal regulatory T cell (Treg) therapy may facilitate reduction promoting better long-term clinical outcomes. In a Phase I trial, 12 recipients received 1–10 × 106 Treg per kg at Day +5 posttransplantation lieu of induction (Treg Therapy cohort). Nineteen patients standard (Reference Primary were...
We and others have previously described signatures of tolerance in kidney transplantation showing the differential expression B cell–related genes relative expansions cell subsets. However, all these studies, index group—namely, tolerant recipients—were not receiving immunosuppression (IS) treatment, unlike rest comparator groups. aimed to assess confounding effect regimens develop a novel IS-independent signature tolerance. Analyzing gene three independent transplant patient cohorts (232...
Introduction Psychological distress is common in end-stage kidney disease (ESKD) and associated with poorer health outcomes. Cognitive behavioural therapy (CBT) recommended UK clinical guidelines for the management of depression people long-term conditions. Access to skilled therapists competent managing competing mental physical demands ESKD limited. Online CBT treatments tailored needs population offers a pragmatic solution under-resourced services. This study examines feasibility...
The risk of COVID-19 infection in transplant recipients (TRs) is unknown. Patients on dialysis may be exposed to greater due an inability isolate. Consideration these competing risks important before restarting suspended programs. This study compared outcomes kidney and kidney/pancreas TRs with those the waiting list, following admission a high-prevalence region.Audit data from all 6 London centers were amalgamated. Demographic laboratory collected included mortality, intensive care (ITU)...
There is accumulating evidence that cell surface molecules may be transferred between cells during an encounter. The aim of these experiments was to determine whether transfer allogeneic material T could influence human alloresponses. CD4(+) were cocultured with M1 (human fibroblast) transfectants expressing HLA-DR1, CD80 and CD86 alone or in combination. Up 95% the became positive for HLA-DR appropriate costimulatory after only 4 h coculture. phenomenon required contact membrane fluidity...
Immunosuppressive drugs are essential for the prevention of acute transplant rejection but some may not promote long-term tolerance. Tolerance is dependent on presence and regulatory function CD4+CD25+ T cells in a number animal models. The direct effects immunosuppressive cells, particularly those that interfere with IL-2 signaling uncertain. We studied rapamycin derivative everolimus anti-CD25 monoclonal antibody basiliximab capacity human vitro. Both permitted suppression proliferation...
Background. There are no clear guidelines on renal transplantation in patients with antineutrophil cytoplasmic antibody (ANCA)-positive vasculitis. Methods. We undertook a survey of transplant centres across Europe to assess whether there was consensus about how manage then identified 107 allograft recipients whose primary disease systemic vasculitis and assessed their outcome post-transplant. Results. All questionnaire respondents felt that should be remission at transplantation, 16%...
CD4(+)CD25(+) and CD1d-restricted natural killer T (NKT) cells are thymus-derived self-reactive regulatory that play a key role in the control of pathological immune responses. Little is known about functional cooperation between innate NKT adaptive cells. Here we show human CD4(+)Valpha24(+)Vbeta11(+) (CD4(+) NKT) isolated from peripheral blood by flow cytometric cell sorting secrete substantial amounts IL-2 after stimulation with dendritic (DC) alpha-Galactosylceramide. When cocultured...
Harnessing naturally arising CD4+ CD25+ regulatory T cells (Tregs) for potential adoptive cell therapy is hampered by their innate autoreactivity and limited number.CD4+ Tregs were purified from peripheral blood of human leukocyte antigen (HLA) DR1*0101+ A2- individuals, stimulated with autologous monocyte-derived dendritic (DCs).Here we show that specific an HLA A2 (103-120) peptide can be selected the population a healthy individual detected using tetramer comprised DRB1*0101 peptide. The...
CD4(+)CD25(+) regulatory T cells have been shown to regulate a variety of autoimmune and allogeneic responses in mice humans. The role regulating alloresponses human transplant recipients remains uncertain. Previous research has demonstrated reduced frequency direct pathway donor-specific renal when compared with the reactive an HLA-matched third party. A number mechanisms proposed account for this finding; purpose study was determine whether play significant role. Twelve stable patients...

Kidney transplant recipients (KTRs) with "operational tolerance" (OT) maintain a functioning graft without immunosuppressive (IS) drugs, thus avoiding treatment complications. Nevertheless, IS drugs can influence gene-expression signatures aiming to identify OT among treated KTRs.
