An In Vitro Model of Human Antibody-Mediated Rejection Depicts Key Role for NK Cells
L. Hidalgo,¹ M. Racape,² A. Loupy,² C. Lefaucheur.²
¹Lab. Med. and Pathology, University of Alberta, Edmonton, AB, Canada; ²Paris Cardiovascular Research Center INSERM, Paris, France.
AIM: Antibody-mediated rejection (ABMR) is the leading cause of kidney allograft loss but its immune mechanisms are incompletely understood. We sought to examine key interactions…

NKG2C+CD57+ NK (G2C+57+) Cells Expanded by CMV Infection Are Highly Responsive to Allo-Antibody (Ab)-Mediated NK Cell Stimulation
B. Shin,¹ D. Puliyanda,² H. Pizzo,² S. Jordan,² M. Toyoda.¹
¹Transplant Immunology Laboratory, Cedars-Sinai Medical Center, Los Angeles, CA; ²Comprehensive Transplant Center, Cedars-Sinai Medical Center, Los Angeles, CA.
Introduction: Active CMV infection is known to be associated with risk for ABMR in allograft recipients. Ab-dependent cellular cytotoxicity (ADCC) primarily mediated by NK cells…

The Beneficial Effects of mTOR Inhibitors on Liver Resident Natural Killer Cells.
J. Saparbay, Y. Tanaka, T. Yano, H. Ohdan.
Gastroenterological and Transplant Surgery, Hiroshima University, Hiroshima, Japan
(Background) The immunosuppressive regimen currently used after organ transplantation reduces adaptive components. Therefore, the innate immune cells play pivotal roles in immune surveillance and defense…

CD16a-Activated NK Cells in ABMR Are Highly Similar to CD3-Activated Effector T Cells in TCMR.
M. Parkes, P. Halloran, L. Hidalgo.
University of Alberta, Edmonton, Canada
BACKGROUND: NK cell CD16a and T cell CD3 activate shared pathways. Since NK cell CD16a activation occurs in antibody-mediated rejection (ABMR) and T cell CD3…
