The Preclinical Application of the Tactile Discrimination Task in Rat Models
Nerve reinnervation is an important issue in the field of vascularized composite allotransplantation (VCA). However, nowadays the effective treatment for enhancing the reinnervation after the…2018 American Transplant Congress
Tomotherapy and Donor Hematopoietic Cells for Tolerance to Kidney Transplants in Rhesus Macaques
The goal of this project was to develop a tolerance induction protocol for MHC 1-haplotype mismatched kidney transplants (txs) in a rhesus macaque model. The…2018 American Transplant Congress
Immunomodulation of Alloantibody Responses
Center for Transplantation Sciences, Massachusetts General Hospital, Boston, MA.
We have shown that i.v. exposure to MHC-mismatched donor PBMC using a novel, mild conditioning protocol results in B-cell tolerance with transient T-cell unresponsiveness. Here…2018 American Transplant Congress
Successful Patency in Blood Conduits for an Artificial Kidney Membrane with Biocompatible Coatings
1VUMC, Nashville; 2UCSF, San Francisco.
BACKGROUND: An implantable artificial kidney may address the growing organ shortage and improve outcomes and quality of life for those with end stage renal disease.…2017 American Transplant Congress
Dual Targeting of Costimulation and Proteasome to Desensitize and Prolong Graft Survival of Sensitized Nonhuman Primates.
[Background] Pre-formed donor-specific anti-HLA antibodies (DSA) from prior transplantation, transfusion, or pregnancy affects a significant portion (35%) of patients awaiting a kidney transplant. Highly sensitized…2017 American Transplant Congress
Induction of Proliferative Responses in B Cell and Plasma Cell Populations Following Proteasome Inhibitor Desensitization Treatment in Rhesus Macacques and Humans.
1U of Cincinnati, Cincinnati; 2Duke, Durham; 3Cincinnati Childrens, Cincinnati
Proteasome inhibitor (PI)-based desensitization (DS) in humans has demonstrated variable reduction in HLA antibody levels that is often associated with variable rebound following treatment cessation.The…2017 American Transplant Congress
Combination αCD28+αCD40 Costimulation Blockade Attenuates Acute and Chronic Rejection in Non-Human Primates.
University of Maryland School of Medicine, Baltimore, MD
Purpose: Monotherapy using αCD28 or αCD40 antibodies significantly prolongs graft survival but does not induce tolerance in non-human primates (NHP). Here, we evaluate the relative…2017 American Transplant Congress
Does Blockade of ICOS/ICOS-L Pathway Act Synergistically with αCD40 Costimulation Pathway Blockade?
University of Maryland School of Medicine, Baltimore, MD
Purpose: Inducible costimulator (ICOS) on T cells enhances basic T cell responses to foreign antigen, and increased ICOS expression is detected in association with pathogenic…2016 American Transplant Congress
Ex Vivo Expansion and Functional Characterization of Human Alloantigen-Specific Regulatory T Cells.
Purpose: Regulatory T cells (Tregs) have been associated with clinical transplant tolerance and they have been shown to prolong graft survival in animal models without…2016 American Transplant Congress
Radiosensitive Cell Population Prolongs Graft Survival of Vascularized Composite Allografts in Non-Human Primates.
University of Maryland School of Medicine, Baltimore, MD.
Background: Vascularized composite allografts (VCA) containing vascularized bone marrow (VBM) prolong graft survival. To help elucidate this protective immunomodulatory effect, we irradiated donor facial VCA…
