Analysis of Circulating CD38+/CD138+ Plasma Cells during Development of De Novo Donor Specific Antibody Responses
N-.N. Chai, G. Wu, I. Kim, S. Jordan, A. Klein.
CTC/Surgery, Cedars-Sinai Medical Center, Los Angeles, CA.
Purpose: Donor specific antibodies (DSA) that emerge following transplantation are indicative of allogenic sensitization and a predisposing factor for antibody mediated rejection. Though various methods…

HLA-DR Based Murine Transplant Model for Studying Collagen Type V Autoimmunity in Chronic Allograft Rejection.
V. Agashe, Y. Zhou, E. Jankowska-Gan, W. Burlingham.
Dept. of Surgery/Transplant Division, UW Madison, Madison, WI
Background: In lung and heart transplant patients, chronic rejection manifests as fibro-obliteration of airways and vessels resulting in bronchiolitis obliterans syndrome (BOS) or cardiac allograft…

CTLA4Ig Suppresses Memory Responses to HLA-A2⁺ Skin Grafts in a Mouse Model of Allosensitization by Reducing CD138⁺ Plasma Cells.
G. Wu, I. Kim, N.-N. Chai, S. Jordan, A. Klein.
Comprehensive Transplant Center, Cedars-Sinai Medical Center, Los Angeles, CA
Purpose: In previous studies we demonstrated that CTLA4Ig suppresses de novo T-cell activation through blocking CD28 co-stimulation and attenuates recall alloantibody responses following re-exposure to…
