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…2020 American Transplant Congress
Serum CXCL13 Levels Indicate Humoral Alloreactivity and Donor Specific Antibody Formation
*Purpose: Donor-specific antibodies (DSA) are an increasingly recognized cause of allograft injury, yet biomarkers to predict their development or guide their clinical management post-transplant are…2020 American Transplant Congress
Autoimmune Responses to DNA Topoisomerase I Exacerbate Renal Allograft Injury
Inflammation and Immunity, Cleveland Clinic, Cleveland, OH
*Purpose: Multiple clinical and pre-clinical studies describe correlations between de novo autoimmune responses and poor transplant outcome. We have previously reported that following renal transplantation,…2020 American Transplant Congress
XBP1 Modulates Endoplasmic Reticulum and Mitochondria Crosstalk via Regulating NLRP3 Inflammasome in Renal Ischemia/Reperfusion Injury
*Purpose: This study aims to investigate the molecular mechanism and function of X-box binding protein 1 (XBP1)- NLR family pyrin domain-containing 3 (NLRP3) signaling which…2020 American Transplant Congress
CD4+ T-Cells Express High Levels of Messenger RNA Coding for Heparanase in Cultures with Matrigel
Cedars-Sinai Med Ctr, Los Angeles, CA
*Purpose: Heparanase (Hpse) is the sole heparan sulfate (HS) degrading enzyme regulating multiple biological activities that enhance immune cell migration, blood vessel growth and cell…2020 American Transplant Congress
A Technique for Ex-Vivo Perfusion of Donor Kidneys for Transplantation in the Mouse
*Purpose: Ex-vivo perfusion of donor kidneys is widely employed in the US and significantly reduces DGF. Development of a pre-clinical perfusion technique may provide an…2020 American Transplant Congress
The Effect of Undernutrition and Immunosuppression on Cytomegalovirus Specific T Cell Responses
1Pediatrics, Duke University, Durham, NC, 2Surgery, Duke University, Durham, NC
*Purpose: Cytomegalovirus (CMV) infection remains a significant issue in transplantation, especially in those who are undernourished. While undernutrition is associated with impaired T cell immunity…2020 American Transplant Congress
Late Onset Primary Graft Dysfunction after Lung Transplantation Correlates with Transplant Arteriosclerosis in a Humanized Mouse Model
*Purpose: Primary Graft dysfunction (PGD) is one of the most important causes of early mortality after lung transplantation. We investigated the correlation between the incidence…2020 American Transplant Congress
Undernutrition and Hypoleptinemia Modulate Cytomegalovirus Infection
1Pediatrics, Duke University, Durham, NC, 2Surgery, Duke University, Durham, NC
*Purpose: Cytomegalovirus (CMV) viremia/infection remains a significant cause of morbidity in transplantation, especially in the undernourished population. Undernutrition and hypoleptinemia have been implicated in other…2020 American Transplant Congress
Proteomics and Metabolomics Technologies Reveal the Effect of Oxygen in Hypothermic Machine Perfusion to Alleviate Donation after Circulatory Death Liver Injury
*Purpose: To compare the effects of oxygenated and nitrogenated hypothermic machine perfusion on the preservation of donation after circulatory death (DCD) livers, and to explore…
