Direct Alloimmunity Is Driven by Recipient APCs Displaying Donor MHC Molecules.
We have studied the trafficking of donor passenger leukocytes and donor MHC presentation in the lymphoid organs of mice having received an MHC-mismatched skin or…2016 American Transplant Congress
Evaluation of Conformational Diversity of a Single HLA-I Molecule Coated on Single Antigen Beads: Potential Impact on Organ Allocation?
Terasaki Foundation Laboratory, Los Angeles, CA.
Recombinant HLA-I (rHLA-I) molecules are the antigenic targets used to screen HLA-I DSA in the sera of pre- or post-transplant patients. A conformational diversity, β2-microglobulin-associated…2016 American Transplant Congress
Metallothionein Accelerates Anti-MHC Induced Small Airway Obliteration and Fibrosis by Negatively Regulating IL-10 and Regulatory Cells.
Development of bronchiolitis obliterans syndrome (BOS), chronic lung allograft rejection, is a major obstacle to long-term success from lung transplantation. De novo antibodies (Abs) to…2015 American Transplant Congress
Highly Accurate High-Resolution HLA Imputation Using Dense Genotyping Data
HLA similarity between donors (D) and recipients (R) of solid organ transplantation (SOT) plays a central role in determining the risk of rejection or graft-versus-host…2015 American Transplant Congress
Immunomodulatory Strategies Directed Towards Tolerance of Vascularized Composite Allografts
Background: Achieving tolerance of vascularized composite allografts (VCAs) would improve the risk-to-benefit ratio in patients who undergo this life-enhancing transplant. Kidney co-transplantation along with a…2015 American Transplant Congress
Antibody-Induced Platelet Activation Increases Allograft Hyaluronan Fragmentation
Antibodies to MHC class I antigens have been shown to activate endothelial cells to release von Willebrand factor (vWf) and P-selectin from storage granules. These…2015 American Transplant Congress
Regulatory Tolerance Across a Full MHC Barrier Is More Robust Than Tolerance Across a Class I MHC Disparity Alone
Background: We previously demonstrated that tolerance of hearts and/or kidneys achieved across a class I MHC mismatch with 12 days of CyA can be abrogated…2015 American Transplant Congress
The Forgotten Cell: Renal Fibroblasts Are Activated By Anti-MHC Class I Antibody
Medicine and Surgery, University of Alabama at Birmingham, Birmingham, AL.
Chronic antibody-mediated (CAMR) rejection remains a major obstacle in the long term survival of kidney transplants, and is associated in part with interstitial fibrosis (IF)…2015 American Transplant Congress
Donor MHC Independent Rejection of Islet Allografts in Autoimmune NOD Mice
In autoimmune Type 1 diabetes (T1D), pancreatic islet allografts have somewhat limited long-term survival, both in T1D human subjects and in spontaneously diseased non-obese diabetic…2015 American Transplant Congress
Monocyte Recruitment to HLA Class I Antibody-Activated Endothelial Cells Is Dependent Upon mTOR
Pathology & Laboratory Medicine, UCLA, Los Angeles, CA.
Aim: Antibody-mediated rejection (AMR) persists as a major issue affecting solid organ transplants. The purpose of this study was to investigate the proximal signaling events…
