    Defining Response to Standard of Care Treatment in Kidney Recipients with Antibody-Mediated Rejection: Role of C1q-Binding Donor-Specific Anti-HLA Antibodies

    Y. Bouatou, D. Viglietti, O. Aubert, A. Loupy, C. Lefaucheur.

    Paris Translational Research Center for Organ Transplantation, Paris, France.

    A major hurdle to improving clinical care in kidney transplantation is the lack of biomarkers of the response to antibody-mediated rejection (ABMR) treatment. We investigated…
