Characterization of peripheral B cells in patients at time of acute rejection (AR) or controls. (a) In all samples immunoglobulin (Ig)M gene expression levels remained stable, whereas (b) IgG gene expression levels were decreased at time of AR. (c) Polyclonal B cell activation did not show a difference in proliferative capacity between patients with AR or stable patients, or within the patient groups in time. (d) Ratio of IgM over IgG producing numbers of B cells upon polyclonal activation as measured by enzyme‐linked immunospot (ELISPOT) revealed that patients with AR and patients with stable graft function show a similar increase in IgM‐producing B cells from the moment of discharge. Level of significance: *P < 0·05, **P < 0·01, ***P < 0·001.
