  • The Role of B Cells in Patients Who Accept Their Kidney Graft without Any Treatment

In organ transplantation, allo-antibodies have been shown to be the hallmark of allograft loss. They have been shown to precede both cellular acute- and chronic-rejection. Nevertheless, several examples in the literature have shown that they are not always associated with histological evidence of antibody-mediated injury. Moreover, patients with episodes of rejection have evidence of B cell-infiltrate suggesting that B cell-activation may also contribute to graft injury by other mechanisms than direct antibody-mediated graft injury. As transplant recipients who permanently accept their grafts in the absence of immunosuppression rarely develop an allo-immune response and may not display an ‘optimal’ response to alloantigens, we hypothesized that regulation and/or control of this response may take place in these patients and that B cells could also play a role in establishing the process of tolerance. This study should help to understand how to manipulate B cells to improve long-term graft outcome.
