IgM in the blood of normal individuals consists mainly of 'natural' polyreactive antibodies. Natural IgM is thought to provide an initial defense against infection and to promote the healing of wounded cells. Yet, as Panzer and colleagues show, these benefits can be eclipsed when the IgM binds to damaged cells of the glomerulus, activating complement. IgM in glomeruli thus signifies cellular damage and may warn that the pace of that damage exceeds the capacity for repair.
