Anti-CD40 mAb Promotes Kidney Immunoregulatory Capacity in NHP Transplants by Altering Kidney Tubular Cell (TEC) Expression of CD40 and IL-6.
Treatment of cynolmolgus monkey (NHP) renal transplant recipients with a combination of 2 rhesus-mouse chimeric α-CD45RB (r6G3R1; 6G3) and α-CD40 (r2C10R4; 2C10) mAbs increased circulating…2017 American Transplant Congress
Memory T Cells Are Decreased in Transplant Recipients Deficient in miR-182.
Transplant Immunology Lab/Division of Abdominal Transplant, Stanford University, Stanford
MicroRNAs (miRNAs) are small non-coding RNA molecules that regulate the post-transcriptional expression of target genes. There is ample evidence that miRNAs are involved in the…2017 American Transplant Congress
Combination αCD28+αCD40 Costimulation Blockade Attenuates Acute and Chronic Rejection in Non-Human Primates.
University of Maryland School of Medicine, Baltimore, MD
Purpose: Monotherapy using αCD28 or αCD40 antibodies significantly prolongs graft survival but does not induce tolerance in non-human primates (NHP). Here, we evaluate the relative…2017 American Transplant Congress
Ex vivo Expanded Regulatory T cells Combined with Short-Term Costimulation Blockade Prevent Rejection of Vascularized Composite Allografts.
Plastic and Reconstructive Surgery, Johns Hopkins University School of Medicine, Baltimore, MD
[Background] Reconstructive transplantation represents a valid therapeutic option after devastating tissue loss. Routine clinical application, however, is hampered by the toxicity of long-term maintenance immunosuppression.…2017 American Transplant Congress
Dual Costimulatory Blockades Failed to Achieve Transplant Tolerance Despite Induction of Mixed Chimerism in NHPs.
Background: Our previous studies showed that substantial deletion of CD8+ memory T cells (TMEM) was necessary to induce mixed chimerism (MC) and allograft tolerance when…2017 American Transplant Congress
Chimerism-Related Allotolerance Is Induced by Exosome Acquisition and Reprogramming of Host Dendritic Cells.
Maternal microchimerism (MMc) has been associated with allo-specific graft tolerance in mice and humans. This tolerance is associated with membrane allo-antigen acquisition (mAAQ), which is…2017 American Transplant Congress
Extracellular Mitochondria Cause B7 Costimulation Blockade Resistant Allograft Rejection in Mice.
1Surgery, Duke University, Durham, NC; 2Immunology, Duke University, Durham, NC
Introduction: Mitochondria released in the setting of tissue injury and cell death are a source of damage-associated molecular patterns that activate innate immune responses. We…2017 American Transplant Congress
Does Blockade of ICOS/ICOS-L Pathway Act Synergistically with αCD40 Costimulation Pathway Blockade?
University of Maryland School of Medicine, Baltimore, MD
Purpose: Inducible costimulator (ICOS) on T cells enhances basic T cell responses to foreign antigen, and increased ICOS expression is detected in association with pathogenic…2017 American Transplant Congress
Dual Targeting of Costimulation and Proteasome to Desensitize and Prolong Graft Survival of Sensitized Nonhuman Primates.
[Background] Pre-formed donor-specific anti-HLA antibodies (DSA) from prior transplantation, transfusion, or pregnancy affects a significant portion (35%) of patients awaiting a kidney transplant. Highly sensitized…2017 American Transplant Congress
FcγRIIB-Mediated Coinhibition Attenuates Donor-Reactive CD8+ T Cell Responses.
Emory Transplant Center, Emory University, Atlanta, GA
Memory T cells can be a formidable barrier to long-term, rejection-free allograft survival, particularly in the setting of costimulation blockade. Ongoing work in the field…
