    Donor-Specific Antibody Mediates Chronic, but Not Acute, Kidney Allograft Rejection in the Absence of Natural Killer Cells

    T. Yagisawa, N. Dvorina, A. Valujskikh, W. Baldwin 3rd, R. Fairchild.

    Immunology and Glickman Urological Institute, Cleveland Clinic, Cleveland, OH.

    The incidence of antibody-mediated kidney graft rejection continues to increase. We previously reported that dysregulated donor-specific antibody (DSA) responses were induced in B6.CCR5-/- mice transplanted…
