2B4 Over-Expression Impairs Donor-Reactive CD8+ T Cell Proliferation and Accumulation Following Transplantation.
S. Laurie, D. Liu, M. Ford.
Emory Transplant Center, Emory University School of Medicine, Atlanta, GA.
T cell function is tightly regulated by a fine balance of coinhibitory signals, including those transduced by 2B4 (SLAMf4, CD244), an immunoglobulin-superfamily member constitutively expressed…

Sepsis Prolongs Allograft Survival Compared with Non-Septic Infection in a Murine Model of Skin Transplantation and Pseudomonas aeruginosa Pneumonia.
L. Margoles, S. Laurie, C. Coopersmith, M. Ford.
Emory Transplant Center, Department of Surgery, Emory University, Atlanta, GA.
Concurrent infections have been shown to increase risk of transplant rejection via enhanced innate immune activation and increased T cell alloreactivity. In some cases, these…

Type-I Interferon Induced Cross-Competition of IL-10 Signaling and Its Role in the Abrogation of Transplant Tolerance.
M. Iglesias, A. Arun, W. Lee, G. Brandacher, G. Raimondi.
Plastic Surgery, Johns Hopkins University, School of Medicine, Baltimore, MD.
PurposeA growing body of evidence shows that induction of long term transplant survival by “costimulation blockade” (CoB) regimens is impaired by inflammatory responses. In particular,…
