C1-INH for Refractory Antibody Mediated Renal Allograft Rejection

This is an open-label, single arm trial in which patient who have ongoing antibody mediated rejection of a kidney transplant deemed refractory to maximal medical therapy are given the comp...

Clazakizumab for Chronic and Active Antibody Mediated Rejection Post-Kidney Transplant

Antibody mediated rejection (ABMR) is a unique, significant and often severe form of allograft rejection. This single center, phase I/II, open label single-arm exploratory study focuses on...

Comparison Between Bortezomib and Rituximab Plus Plasmapheresis in AMR

Chronic-active antibody-mediated rejection (cAMR) due to de novo or pre-formed donor specific antibody (DSA) is currently considered the main cause of long-term allograft losses.Based on t...

Interleukin 6 Blockade Modifying Antibody-Mediated Graft Injury and Estimated Glomerular Filtration Rate (eGFR) Decline

This trial investigates whether clazakizumab (an anti-interleukin (IL)-6 monoclonal antibody (mAb)) may be beneficial for the treatment of CABMR in recipients of a kidney transplant by inh...

A Pilot Study to Evaluate the Use of C1 Esterase Inhibitor (Human) in Patients With Acute Antibody-Mediated Rejection

The purpose of this research study is to evaluate the safety, effect, and pharmacology of C1 Esterase Inhibitor (human) in kidney transplant patients with Antibody-Mediated Rejection (AMR)...

Systematic testing and specificity mapping of alloantigen-specific chimeric antigen receptors in T regulatory cells.

Chimeric antigen receptor (CAR) technology can be used to engineer the antigen-specificity of regulatory T cells (Tregs) and improve their potency as an adoptive cell therapy in multiple disease model...

Diagnostic application of kidney allograft-derived absolute cell-free DNA levels during transplant dysfunction.

Graft-derived cell-free DNA (donor-derived cell-free DNA) is an emerging marker of kidney allograft injury. Studies examining the clinical validity of this biomarker have previously used the graft fra...

The Regulation of IFN Type I Pathway Related Genes RSAD2 and ETV7 Specifically Indicate Antibody-Mediated Rejection After Kidney Transplantation.

Antibody-mediated rejection (ABMR) after kidney transplantation (KTx) remains the crucial obstacle to successful long-term graft function. The identification of gene signatures involved in ABMR could ...

The Role of B Cell Immunity in VCA Graft Rejection and Acceptance.

Vascularized composite allotransplantation (VCA) has emerged as the most recent field of transplantation to offer an alternative treatment for those patients that have failed or are not suitable candi...

Trametinib Attenuates Delayed Rejection and Preserves Thymic Function in Rat Lung Transplantation.

Delayed immunological rejection following human lung transplantation causes chronic lung allograft dysfunction (CLAD), which is associated with high mortality. Delayed rejection may be attributable to...

Medical and Biotech [MESH] Definitions

The induction of prolonged survival and growth of allografts of either tumors or normal tissues which would ordinarily be rejected. It may be induced passively by introducing graft-specific antibodies from previously immunized donors, which bind to the graft's surface antigens, masking them from recognition by T-cells; or actively by prior immunization of the recipient with graft antigens which evoke specific antibodies and form antigen-antibody complexes which bind to the antigen receptor sites of the T-cells and block their cytotoxic activity.

The immune responses of a host to a graft. A specific response is GRAFT REJECTION.

Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific antigens. It may also occur in vivo as in GRAFT REJECTION.

Large transmembrane, polymorphic glycoproteins noncovalently associated with nonpolymorphic beta 2-microglobulin. In humans, three structural genes on chromosome 6 code for the HLA-A; HLA-B and HLA-C antigens. In mice, three genes named K, D, and L on chromosome 17 code for the H-2 antigens. Class I antigens are found on most nucleated cells and are generally detected by their reactivity with alloantisera. These antigens are recognized during graft rejection and restrict cell-mediated lysis of virus-infected cells. They are primarily associated with rheumatologic diseases and certain malignant disorders.

A form of ischemia-reperfusion injury occurring in the early period following transplantation. Significant pathophysiological changes in MITOCHONDRIA are the main cause of the dysfunction. It is most often seen in the transplanted lung, liver, or kidney and can lead to GRAFT REJECTION.
