BACKGROUND: An increased percentage of peripheral transitional B cells producing
IL-10 has been observed in patients tolerant to kidney allografts. In healthy
volunteers, the balance between the CD40 and B-cell receptor (BCR) signalling
modulated IL-10 production by B cells, with stimulation via the BCR decreasing
CD40-mediated IL-10 production. In this study, we evaluate whether in tolerant
kidney transplant patients, the increased IL-10 production by B cells was due to
an altered CD40 and/or BCR signalling. METHODS: B cells obtained from a new
cohort of tolerant renal transplant recipients and those from age- and
sex-matched healthy volunteers were activated via CD40 and BCR, either alone or
in combination. RESULTS: In tolerant patients, we observed higher percentages of
B cells producing IL-10 after CD40 ligation and higher expression of CD40L on
activated T cells compared with healthy controls. Furthermore, B cells from
tolerant recipients had reduced extracellular signal-regulated kinase signalling
after BCR-mediated activation compared with healthy controls. In keeping with
this, combining BCR signalling with CD40 ligation did not reduce IL-10 secretion
as was observed in healthy control transitional B cells. CONCLUSIONS: Altogether,
our data suggest that the altered response of B cells in tolerant recipients may
contribute to long-term stable graft acceptance.
