Use The Vascularized Sentinel Skin Flap For Prophylaxis Of Antibody-mediated Rejection After Kidney Transplantation In Highly Sensitized Patients
*Purpose: Patients with high titer of preexisting donor specific anti-HLA antibodies (DSA) have very high risk of antibody mediated rejection development and followed by the…2022 American Transplant Congress
Role of Group 2 Innate Lymphoid Cells in Murine Heart Transplant
*Purpose: Group 2 innate lymphoid cells (ILC2s) have been shown to play key roles in manipulating adaptive immunity. They regulate CD4+ T cell biology not…2022 American Transplant Congress
Contributions of Allogenicity and Antigen Presentation to Regulatory B Cell Suppression
Center for Transplantation Sciences, Boston, MA
*Purpose: We previously generated in vitro Toll-like receptor (TLR)-activated B cells became regulatory B cells (Bregs) that suppress T cell proliferation and promote allograft tolerance.…2021 American Transplant Congress
Marginal Zone B Cells Support Donor-Specific Alloantibody Responses to Heart Allografts
Inflammation and Immunity, Cleveland Clinic, Cleveland, OH
*Purpose: Production of high affinity isotype-switched donor specific alloantibodies (DSA) after transplantation is associated with germinal center formation by follicular (FO) B cells whereas the…2021 American Transplant Congress
Combined Donor Derived Cell Free DNA (AlloSure) and Peripheral Immune Cell Gene Expression (AlloMap) Testing for the Diagnosis of Rejection in Kidney Transplant Recipients with De Novo Donor Specific Antibodies
University of Wisconsin, Madison, WI
*Purpose: Combined donor-derived cell-free DNA (dd-cfDNA, AlloSure) and peripheral immune cell gene expression (AlloMap) may increase the predictive value of de novo DSA (dnDSA) for…2021 American Transplant Congress
Risk Stratification of Kidney Transplant Patients According to the Different Level of HLA-DQ Disparities
*Purpose: It is becoming clear that de novo donor-specific antibodies (dnDSA) against HLA-DQ are the most prevalent and the leading cause of chronic antibody-mediated rejection…2021 American Transplant Congress
Association Between HLA Class II and TLR4 Regulates HLA-II Stimulated P-selectin Expression and Monocyte Capture to Endothelial Cells
Pathology and Laboratory Medicine, University of California Los Angeles, Los Angeles, CA
*Purpose: Antibody-mediated rejection (AMR) is a major obstacle for long-term allograft survival. Donor specific HLA antibodies (DSA) contribute to the process of AMR by binding…2020 American Transplant Congress
HLA Molecular Mismatch is an Independent Correlate of T-Cell Mediated Rejection and Potential Prognostic Biomarker in Renal Transplantation
*Purpose: HLA molecular mismatch alloimmune risk categorization has correlated with de novo donor-specific antibody (dnDSA) development, however, correlation with T-cell mediated rejection (TCMR) phenotypes is…2020 American Transplant Congress
Thymic B Cells: A Means to Control Regulatory Tolerance
*Purpose: Therapies involving CD4 regulatory T cells (Tregs) are promising approaches to mitigate graft rejection and autoimmunity. Understanding of the activation mechanisms that initiate Treg…2020 American Transplant Congress
Influence of HLA Compatibility on Cytomegalovirus Infection Post-Kidney Transplantation
*Purpose: Cytomegalovirus (CMV) infection after kidney transplantation is associated with a high morbidity and higher risk of graft loss. A latent Human CMV infection can…
