Expression Patterns of Neuropilin-1 On T Cells and a Potential Role in Transplantation
Department of Surgery, Boston Children's Hospital and Harvard Medical School, Boston, MA.
Introduction: Neuropilin-1 (NRP1) is a co-receptor for a variety of ligand families including VEGF, EGF and semaphorins all of which are often produced by malignant…2015 American Transplant Congress
Increased Frequency of Terminally Differentiated and Exhausted CD8+ T Cells Is Associated With Adverse Clinical Outcome After Mechanical Circulatory Support Device Implantation
Clinical outcomes vary after mechanical circulatory support device (MCSD) implantation, with some patients developing multi organ system dysfunction (MOD), sometimes leading to death. We hypothesized…2015 American Transplant Congress
Donor Specific Expansion of Regulatory T-Cells Was Associated With Allograft Tolerance Induced By Transient Mixed Chimerism in Nonhuman Primates
Transplant Center, Massachusetts General Hospital, Boston, MA.
Background: We have previously reported successful induction of solid organ allograft tolerance in nonhuman primates (NHP) via a mixed chimerism approach. Since these recipients achieved…2015 American Transplant Congress
Interleukin-17A Induced Human Mesenchymal Stem Cells Are Superior Modulators of Immunological Function
Interferon-gamma preactivated mesenchymal stem cells (MSC-γ) are highly immunosuppressive but immunogenic in vivo due to their inherent expression of major histocompatibility (MHC) molecules. We modified…2015 American Transplant Congress
The Immunosuppressive Effect of CTLA4Ig Monotherapy Depends On the Presence of Tregs Only at Suboptimally Low Doses
Background: CTLA4Ig/belatacept has been recently approved for immunosuppression after renal transplantation. Concerns persist, however, that a paradoxical dose-response relationship might exist for CTLA4Ig in which…
