General description
Acute humoral rejection is mediated by antibodies to the donor endothelium that activates the classical complement pathway. This leads to a number of split products of complement proteins. C4d is a fragment of C4 complement released during activation of the classic complement pathway by the antigen-antibody complex. C4d deposits in peritubular capillaries and is regarded as an indirect sign of an antibody response. C4d can be a useful tool for indicating acute renal allograft rejection.
