T-Cell Aging Parameters in the Lymph Node and Peripheral Blood Are Strongly Associated but Terminally Differentiated T Cells Are Mainly Located within the Circulation.
IntroductionAgeing is associated with changes in the peripheral T-cell immune system, which can be significantly influenced by latent cytomegalovirus (CMV)-infection. Therefore, we wanted to investigate…2017 American Transplant Congress
Memory T Cells Are Decreased in Transplant Recipients Deficient in miR-182.
Transplant Immunology Lab/Division of Abdominal Transplant, Stanford University, Stanford
MicroRNAs (miRNAs) are small non-coding RNA molecules that regulate the post-transcriptional expression of target genes. There is ample evidence that miRNAs are involved in the…2017 American Transplant Congress
Senescence and Uremia Effects in Circulating T Cells Diverge in TREG Population and Cause T Cell Shift to a Memory Profile.
Elderly kidney transplant recipients(EKtx) have higher malignancies and infections rates, but lower acute rejection incidence. Senescence seems to result in shift to memory profile and…2017 American Transplant Congress
Risks Associated with Recombinant IL2 Therapy in Renal Transplantation.
Brigham and Women's Hospital, Boston
Regulatory T cells are critical to allograft survival. We report a pilot study of safety and tolerability of low dose recombinant IL2 (rIL2), 1x106 units/m2/day…2016 American Transplant Congress
Memory Regulatory T Cell: A Potential Actor in Immunological Operational Tolerance in Kidney-Transplant Patients via the ATP Degradation into Adenosine.
Regulatory T cells (Tregs) are essential actors in the control of self-tolerance and exacerbated inflammation. In experimental transplantation Tregs are critical to achieve alloantigen tolerance…2016 American Transplant Congress
Neutrophil-to-Lymphocyte Ratio as a Predictor of Polyomavirus BK Nephropathy in Kidney Transplant Patients.
Background: Neutrophil-to-lymphocyte ratio (NLR) is an index for systemic inflammatory response, and has been reported to be a prognostic marker in the patients with malignancies…2016 American Transplant Congress
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…
