Activation of T cells induces immunoglobulin (Ig)M-to-IgG B-cell isotype switching via costimulatory regulatory pathways. Because rejection of transplanted organs is preceded by alloantigen-dependent T-cell activation, we investigated whether B-cell isotype switching could predict acute cellular rejection and the subsequent development of transplantation-related coronary artery disease (TCAD) in cardiac transplant recipients.
