Spleen Tyrosine Kinase (syk): A Novel Regulator of Neutrophil Infiltration in Hepatic Iri
Surgery, University of Florida, Gainesville, FL
*Purpose: Hepatic ischemia-reperfusion injury (IRI) plays a governing role in orthotopic liver transplantation, significantly impairing early graft function and increasing organ susceptibility to rejection. Neutrophil…2021 American Transplant Congress
Adjuvant Treatment Shapes the Bone Marrow Myeloid Compartment Towards an Immunosuppressive Phenotype That Can Suppress Allograft Rejection
*Purpose: Myeloid derived suppressor cells (MDSCs) expand in response to inflammatory stimuli and have been shown to suppress adaptive immunity. Preliminary data from our lab…2021 American Transplant Congress
Neutrophil CEACAM1 Induces Hepatic Autophagy and Shapes Innate-adaptive Immune Response in Liver Transplantation: From Mouse-to-human
1Surgery, Dumont-UCLA Transplant Center, Los Angeles, CA, 2Surgery, Kyoto University, Kyoto, Japan
*Purpose: Although CEACAM1 (CC1; carcinoembryonic antigen-related cell adhesion molecule 1; CD66a) regulates innate-adaptive immunity, its role in orthotopic liver transplantation (OLT) remains unknown. CC1 expresses…2021 American Transplant Congress
Double Negative T Cells Mediate Cd39-Dependent Protection in Hepatic Ischemia and Reperfusion Injury
*Purpose: Hepatic ischemia and reperfusion injury (HIRI) is a significant cause of morbidity and mortality following liver transplantation and major hepatic resections. Double negative T…2020 American Transplant Congress
Influence of the Gut Microbiota on Acute Rejection of Vascular Allografts
Molecular Biology and Biochemistry, Simon Fraser University, Burnaby, BC, Canada
*Purpose: The gut microbiota influences immune responses in many ways but its involvement in transplant rejection is poorly understood. We have examined how changes in…2020 American Transplant Congress
FcγRIIIb Inhibits Renal Transplant Rejection by Inducing Neutrophils Apoptosis
Kidney Disease Center, The First Affiliated Hospital of Zhejiang University, Hangzhou, China
*Purpose: Fcγ receptors (FcγR) have been proposed to be involved in the pathogenesis of acute rejection (AR) after organ transplantation. However, the mechanisms by which…2020 American Transplant Congress
Alum Elicited MDSCs Delay the Rejection of Fully Mistmatched Islets in Mice
1Boston Children's Hospital, Boston, MA, 2Massachusetts General Hospital, Boston, MA
*Purpose: Myeloid derived suppressor cells (MDSCs) have been demonstrated to be critical for the induction of tumor induced T cell tolerance and have also been…2019 American Transplant Congress
The Role of Neutrophil Extracellular Traps in Kidney Acute Antibody-Mediated Rejection
*Purpose: Previously our group assessed the spontaneous and lipopolysaccharide-induced NETosis with confocal microscopy in kidney transplant recipients (KTR). We found an enhanced spontaneous NETosis regardless…2019 American Transplant Congress
Soluble Fibrinogen-Like Protein 2 Regulates MDSCs Differentiation and Function in Allograft Immunity
Urology, Zhongshan Hospital, Fudan University, Shanghai, China
*Purpose: Soluble fibrinogen-like protein 2 (sFGL2) is a novel immunoregulatory molecule, secreted mainly by regulatory T cells. CD11b+ Gr1+ myeloid-derived suppressor cells (MDSCs) are an…2019 American Transplant Congress
Human Neutrophil Function against Pathogens in Solid Organ and Stem Cell Transplant Recipients
Transplant Infectious Diseases, Massachusetts General Hospital, Boston, MA
*Purpose: The effects of solid organ (SOT) and allogeneic stem cell transplantation (SCT) on the neutrophil function is not well described. In this study, we…
