C4d protein may be biomarker of ANCA-associated vasculitis activity
People with ANCA-associated vasculitis (AAV) have significantly higher blood levels of C4d, a protein that reflects activation of the classic or lectin complement pathways of the immune system, a study in Sweden suggests. Patients with self-reactive antibodies, called ANCAs, against the proteinase-3 (PR3) protein had significantly higher blood Cd4…
