The Efficacy of Delayed Fc-nonbinding Anti-CD3 Antibody Treatment in Sensitized Allogeneic Mouse Heart Transplantation
T. Ota¹, R. Goto¹, R. Kanazawa¹, K. Shibuya¹, Y. Ganchiku¹, N. Kawamura², M. Watanabe², M. Fukai¹, T. Shimamura³, A. Taketomi¹
¹Dept. of Gastroenterological Surgery I, Hokkaido University, Sapporo, Japan, ²Dept. of Transplant Surgery, Hokkaido University, Sapporo, Japan, ³Division of Organ Transplantation, Hokkaido University Hospital, Sapporo, Japan
*Purpose: Delayed treatment with Fc-nonbinding anti-CD3 antibody (ab) permits early graft infiltrating cells to promotes a transplant tolerance. However, graft infiltrating cells immediate after transplantation…

Platelets Stimulate Liver Regeneration After Partial Liver Transplantation
K. Takahashi, C. Liang, K. Furuya, T. Oda
GI and HBP Surgery, University of Tsukuba, Tsukuba, Japan
*Purpose: Living donor liver transplant (LDLT) can sometimes be associated with impaired regeneration and severe ischemia/reperfusion (I/R) injury in the liver graft, resulting in small-for-size…

Adjuvant Treatment Shapes the Bone Marrow Myeloid Compartment Towards an Immunosuppressive Phenotype That Can Suppress Allograft Rejection
J. Ge¹, E. Anderson¹, J. F. Markmann², A. Cuenca¹
¹Surgery, Boston Children's Hospital, Boston, MA, ²Surgery, Massachusetts General Hospital, Boston, MA
*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…

Single Cell RNAq-seq Analysis of Paired Peripheral and Intragraft T Cells Reveals Biopsy Specific Fc Receptor Gene Expression in Rejection Only
A. Malone, A. Leckie-Harre, I. Silverman, A. Chadha, H. Wu, B. Humphreys
Washington University School of Medicine, St Louis, MO
*Purpose: Antibody mediated rejection (AMR) remains one of the major causes of allograft failure and our understanding of this disease process is poor. Transcriptomics studies…

Regulatory Macrophage Induced by Il-33 Promoted Immune Tolerance of Kidney Transplantation Through Siglec-10
J. d. zhang, w. wang
Urology, Beijing Chaoyang Hospital, Capital Medical University, Beijing, China
*Purpose: Acute and chronic rejection are key problems in renal transplantation. It is ideal to induce immune tolerance to suppress rejection while regulatory macrophages (Mregs)…

Triple-Knockout Pig Red Blood Cells Are a Potential Alternative Source for Clinical Blood Transfusion
T. Yamamoto¹, M. H. Bikhet¹, H. Q. Nguyen¹, M. Javed¹, D. Ayares², H. Iwase¹, H. Hara¹, D. K. Cooper¹
¹Xenotransplantation Program, Surgery, The University of Alabama at Birmingham, Birmingham, AL, ²Revivicor, Blacksburg, VA
*Purpose: Triple-knockout (TKO) pig RBCs (pRBCs) may be an alternative source for clinical blood transfusion because almost humans have no preformed antibody to TKO pRBCs.…
