Lymphotoxin Beta Receptor in Lymphatic Endothelial Cells Regulates Treg Migration and Allograft Protection
*Purpose: Lymphotoxin beta receptor (LTβR) mediated signaling in lymphatic endothelium cells (LEC) is important for migration of regulatory T cells (Treg) to afferent lymphatic vessels…2019 American Transplant Congress
Endothelial Cells Do Not Regulate Expression of CD46, CD55 and CD59 in the Presence of Anti-HLA Class I and 11 Antibodies
*Purpose: Anti-HLA antibodies, both pre-formed and de novo are associated with worse graft survival. Complement activation is an important mechanism of antibody mediated immunological injury.…2019 American Transplant Congress
Platelets Augment Granzyme K Production By Macrophages In Antibody-mediated Rejection
Cleveland Clinic Main Campus, Lerner Research Institute, Cleveland, OH
*Purpose: When antibodies bind to MHC antigens on endothelial cells a cascade of responses is initiated including exocytosis of adhesion molecules followed by attachment and…2019 American Transplant Congress
Lymphotoxin Beta Receptor Determines Lymph Node Structure for Treg Migration and Suppression of Graft Rejection
*Purpose: Lymphotoxin beta receptor (LTβR) mediated signaling in lymphatic endothelium cells (LEC) is important for migration of regulatory T cells (Treg) to afferent lymphatic vessels…2019 American Transplant Congress
Intact Lymphatics Are Essential for Costimulation Blockade-Induced Lung Allograft Survival
*Purpose: Blocking lymphangiogenesis is thought to diminish immune responses to donor tissues. However, lung transplantation (Tx), which involves airway and vascular but not lymphatic anastomoses,…2019 American Transplant Congress
Serum Adipocyte Fatty Acid Binding Protein Level is Negatively Associated with Vascular Reactivity Index Measured by Digital Thermal Monitoring in Kidney Transplant Patients
*Purpose: Adipocyte fatty acid-binding protein (A-FABP) is abundantly found in mature adipocytes, activated macrophages, and dendritic cells and is involved in lipid metabolism, metabolic and…2019 American Transplant Congress
Multiplexed Droplet Single-Cell RNA-Sequencing for Cellular Profiling of Transplant Rejection
Department of Surgery, UCSF, San Francisco, CA
*Purpose: Multiplexed droplet single-cell RNA-sequencing (mdscRNA-seq) has been utilized across many tissue types for fast and paralleled transcriptomic profiling. However, maintaining sample identity for differential…2019 American Transplant Congress
Sphingosine 1-Phosphate Receptors and CCR7 Sequentially Coordinate T Cell Migration
*Purpose: CCR7 plays critical roles in T cell migration to CCL21 across lymphatic endothelial cells from tissues to lymph nodes (LN). S1PR1 and S1PR4 are…2019 American Transplant Congress
Promoting Mitochondrial Fusion Alters the Interaction between Endothelial Cells and T Cells in Models of Transplantation
Medical University of South Carolina, Charleston, SC
*Purpose: As semi-professional antigen-presenting cells, microvascular endothelial cells (mECs) play a central role in mediating allograft rejection. Cold storage and ischemia reperfusion injury increases mEC…2019 American Transplant Congress
Treg Lymphotoxin and Lymphatic Endothelial Cell Lymphotoxin Receptor Interactions Are Required for Treg Stability and Allograft Protection
*Purpose: Regulatory T cells (Treg) restrain allograft rejection through suppressor functions that are dependent upon expression of the transcription factor Foxp3, their proper migration, and…
