A Recombinant, Fully Human ATG Polyclonal Antibody Drug Drives Immune Cell Depletion in a Model of Graft-versus-Host Disease
S. M. Keating, A. S. Adler, R. A. Mizrahi, J. Leong, M. A. Asensio, Y. W. Lim, A. R. Niedecken, Y. Chiang, R. Leong, D. S. Johnson
Immunology, GigaGen, South San Francisco, CA
*Purpose: Anti-thymocyte globulin (ATGs) are polyclonal antibody products that target and deplete T cells for immunosuppression in transplantation (prophylaxis of rejection). Since ATGs are derived…

ESAT-6, A Novel Protein Originally Produced by M. Tuberculosis, Inhibits Central Memory CD8+ T Cell Generation and Allograft Rejection
F. Qiu, S. Ye, H. Liu, Z. Dai
Guangdong Provincial Academy of Chinese Medical Sciences, Guangzhou, China
*Purpose: Allospecific memory T cells pose a threat to long-term allograft survival since they are somewhat resistant to immunosuppression. The objective of this study is…

Granulocyte-Colony Stimulating Factor (G-CSF) and Granulocyte-Macrophage CSF (GM-CSF) Administration Enriches for Highly Suppressive CD4⁺CD45RA^–Foxp3^hi Cells in Leukapheresis Products of Rhesus Monkeys
K. Sasaki, Y. Wang, L. Lu, J. Hughes, V. Vujevich, A. W. Thomson, M. B. Ezzelarab
Starzl Transplantation Institute, University of Pittsburgh School of Medicine, Pittsburgh, PA
*Purpose: In humans, CD4+CD45RA-Foxp3hi T cells comprise a regulatory T cell (Treg) subset with highly suppressive function. We have previously shown that granulocyte-colony stimulating factor…

Inflammatory Cytokines Have a Different Effect from One HLA-II Subclass to Another on Human Endothelium
S. Beland, F. Bouchard-Boivin, A. Gama, O. Desy, S. A. De Serres
Universite Laval, Quebec, QC, Canada

Protective Effect of Fucoidan Against Tacrolimus-Induced Nephrotoxicity in LLC-PK1 Cells
H. J. Jang
Surgery, University of Ulsan, Gangneung Asan Hospital, Gangneung, Korea, Republic of
*Purpose: Tacrolimus (FK506) is an immunosuppressant agent that is frequently used to prevent rejection of solid organs upon transplant. However, nephrotoxicity due to apoptosis and…
