Hepatic Stellate Cells Directly Inhibit B Cells Via PD-L1
Hepatic stellate cells (HSCs) account for one third of the nonparenchymal cells in the liver, which are considered to be critical in maintaining the immunoprivileged…2015 American Transplant Congress
Impact of CXCR4/CXCL12 Blockade on Normal Plasma Cells In Vivo
Receptor/ligand interactions in stromal microenvironments play important roles in the localization, development and survival of normal antibody-secreting plasma cells. The goal of the current study…2015 American Transplant Congress
B Cell Depletion With an Anti-CD20 Antibody Enhances Alloreactive Memory T Cell Response After Transplantation
Pre-transplant B cell depletion in NHP with Rituximab (IgG1 anti-CD20 mAb) combined with cyclosporin A has been shown to promote the survival of islets allografts.…2015 American Transplant Congress
IgM+ Antigen Binding B Cells in Peripheral Blood Regulate IFNγ Production in Response to HLA Proteins
Chronic antibody mediated rejection (CAMR) is a major cause of graft loss in renal transplant recipients. Previous work utilising an IFNγ ELISPOT assay revealed two…2015 American Transplant Congress
The Molecular Landscape of Atrophy-Fibrosis in Human Kidney Transplants: The Dominant Role of Acute Parenchymal Injury
University of Alberta, Edmonton, Canada.
We studied the effect of time post-transplant on atrophy-fibrosis (AF) and molecular associations with AF in 703 kidney transplant indication biopsies (bx) 3 days to…2015 American Transplant Congress
Antibody-Mediated Rejection Is Associated With Higher Serum Levels of CXCL13 and CCL21 in Renal Transplant Patients and Altered By Bortezomib/Rituximab Treatment
In renal transplant patients (pts), B- and plasma cells (PC) are crucial for donor-specific HLA antibody (DSA) formation. The underlying mechanisms, which lead to B…2015 American Transplant Congress
The Effect of Rituximab Therapy on Regulatory B Cell and Prevention of Chronic Antibody Mediated Rejection in Kidney Transplantation Recipients
Urology, Tokyo Women's Medical University, Tokyo, Japan.
We previously reported that a single administration of low dose rituximab (RIT) before kidney transplant reduced the incidence rate of chronic antibody mediated rejection (CAMR)…2015 American Transplant Congress
B-Cell Activation in Acute Kidney Injury and Delayed Graft Function
Background:Acute kidney injury (AKI) is a relevant complication after kidney transplantation and also after non-renal solid organ transplantation. Growing evidence points towards an important role…2015 American Transplant Congress
CFZ533: Assessment of Immunomodulatory Activity Following Single Doses of a Novel Anti-CD40 mAb in Healthy Volunteers
Blocking the CD40-CD154 pathway has been shown to effectively prolong renal allograft survival in non-human primates. CFZ533 is a novel, fully human, Fc-silent, anti-CD40 monoclonal…2015 American Transplant Congress
Assessing Pre-Vaccination Cytokine Levels to Predict Immunogenicity to Seasonal Trivalent Influenza Vaccine in Solid Organ Transplant Recipients
Multi-Organ Transplant Program, University Health Network, Toronto, Canada.
Background: The immunogenicity of seasonal trivalent influenza vaccine (TIV) in solid organ transplant (SOT) recipients remains suboptimal. We hypothesized that analysis of pre-vaccination T- and…
