Innate Lymphoid Cells Play a Key Role in Controlling Antimicrobial Defense in Intestinal Transplant Recipients.
MedStar Georgetown Transplant Institute, Washington DC.
A. Infectious complications are the leading cause of death early after intestinal transplantation (ITx). Etiologies underlying this remain unclear. Innate lymphoid cells (ILCs) have very…2016 American Transplant Congress
Evaluation of a Novel Global Immunity Assay to Predict Infections in Organ Transplant Recipients.
Multi-Organ Transplant, University Health Network, Toronto, Canada.
BackgroundSimple standardized measures of global immunity may help predict the risk of infections post-transplant. The Quantiferon-Monitor (QFM) test is a novel interferon-γ (IFN-γ) release assay…2016 American Transplant Congress
Direct IL-33 Stimulation of T Regulatory Cells via Suppression of Tumorigenicity 2 (ST2) Is Required for Effective Control of Alloimmune Responses.
Background: IL-33 is a pleotropic cytokine that can protect against cardiac transplant rejection by expanding regulatory T cells (Treg), particularly a Treg subset expressing the…2016 American Transplant Congress
NAD+ Promotes Allograft Survival Independently of CD4+CD25+Foxp3+ Regulatory T Cells.
CD4+CD25+Foxp3+ regulatory T cells (Tregs) play a central role in the maintenance of immune tolerance and T cell homeostasis. It is known that Tregs promote…2015 American Transplant Congress
Interim Results of a Phase 1 Trial of Treg Adoptive Cell Transfer (TRACT) in Living Donor Kidney Transplant Recipients
Therapeutic cell transfer using regulatory T cells (Tregs) in transplant recipients may reduce the need for drug based immunosuppression (IS) and improve long term graft…2015 American Transplant Congress
Immunodeficiency Assessment in Pediatric Intestinal Failure Patients
Intestinal failure (IF) is a clinical condition for which intestinal transplantation may be indicated. Patients without enteral autonomy have an increased risk of malnutrition which…2015 American Transplant Congress
Antibody-Mediated Rejection Is Associated With Higher Serum Levels of CXCL13 and CCL21 in Renal Transplant Patients and Altered By Bortezomib/Rituximab Treatment
In renal transplant patients (pts), B- and plasma cells (PC) are crucial for donor-specific HLA antibody (DSA) formation. The underlying mechanisms, which lead to B…2015 American Transplant Congress
Interference of Therapeutic Antibodies Used in Desensitization Protocols On Lymphocytotoxicity Crossmatch Results
Background: Therapeutic antibodies used to desensitize patients awaiting a human leukocyte antigen (HLA) or ABO-mismatched graft are suspected to interfere with the lymphocytotoxicity crossmatch (LCT-XM)…2015 American Transplant Congress
Impact of Alloreactivity On Intra-Graft T Cell Homeostasis Following Small Bowel Transplantation
Columbia University Medical Center, New York.
The impact of alloreactivity on the turnover rate, phenotype and repertoire of gut-resident lymphoid cells populating human intestinal allografts is unknown. We prospectively analyzed the…2015 American Transplant Congress
Lower Frequency of Regulatory T-Cells After Conversion from CNIs or mTORi to Belatacept in a Prospective Matched Controlled Study in Renal Allograft Recipients
Nephrology, Charité Universitätsmedizin Berlin, Berlin, Germany.
Objective: Regulatory T-cells (Tregs) are considered to play a crucial role in maintaining control of immune response following renal transplantation (Tx). So far, only limited…
