Patients Treated with Belatacept Show Low Levels of APRIL and HLA Antibodies.
Belatacept, a fusión protein that blocks the B7-CD28 costimulation pathway, decreases the level of antibodies in non-human primates and murine models but, few studies have…2016 American Transplant Congress
CD4 T Cell Mediated Help Is Required for Intra-Allograft Proliferation of Endogenous Memory CD8 T Cells and Their Ability to Mediate Rejection of Cardiac Allografts Subjected to Prolonged Ischemia.
Immunology, Cleveland Clinic, Cleveland, OH.
Memory T cells are critical components to protective immunity against recurrent pathogens, but memory T cells with donor-reactivity pose a major barrier to successful transplantation…2015 American Transplant Congress
Regulatory T Cells Expanded by Activated iNKT Cells Facilitate Migration of Donor Dendritic Cells Into the Recipient Thymus and Subsequent Establishment of Clonal Deletion
We previously reported that combination therapy using liposomal α-galactosylceramide (lipo-αGC) and anti-CD154 mAb could expand regulatory T cells (Tregs) in vivo through activation of the…2015 American Transplant Congress
Immunosuppression With Anti-CD40 mAb and Rapamycin for Islet and Kidney Co-Transplantation in Nonhuman Primates
Transplant Center, Massachusetts General Hospital, Boston, MA.
Background: For patients with end-stage renal disease secondary to type 1 diabetes mellitus, islet and kidney co-transplantation can be an ideal transplant option. However, a…2015 American Transplant Congress
Distinct Roles of CD137 and CD137L Bi-Directional Signaling in Candida albicans Infection
Invasive fungal infections by Candida albicans frequently cause mortality in immunocompromised patients, yet the cellular processes leading to this mortality remain ill-defined. Here, using genetic…2015 American Transplant Congress
Focal Segmental Glomerulosclerosis Recurrence in Renal Transplant Recipients Treated With Belatacept
Introduction: Focal segmental glomerulosclerosis (FSGS) is a cause of end-stage renal failure that frequently recurs following renal transplant, often leading to early allograft loss. A…2015 American Transplant Congress
Primary and Secondary Vaccine Responses in a Non-Human Primate Model of Cardiac Allotransplantation
Purpose: To compare the effect of calcineurin- versus costimulation-based immunosuppression on primary and secondary vaccine responses in non-human primate heart transplant recipients.Background: Antibody response following…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
Donor Specific Tolerance Can Be Induced by Donor Bone Marrow Transfer With Activation of Invariant Naturel Killer T Cells
It has been reported that liposomal formulation of a-galactosylceramide(lipo-aGC) could induce antigen specific regulatory T cells (Treg) in vivo when administered with particular antigens. We…2015 American Transplant Congress
Induction of a Costimulation-Susceptible Repertoire: A Case for Depletional Prior to Belatacept
1Surgery, Duke University, Durham, NC; 2Transplant Center, Emory University, Atlanta, GA.
Belatacept offers highly specific costimulation blockade to prevent recipient alloimmune responses with reduced toxicity. However, when applied with nondepletional induction therapy belatacept-based regimens have higher…
