Antibody-independent activation of the classical pathway of complement by Epstein-Barr virus.

Abstract

A purified preparation of Epstein-Barr virus (EBV) has been shown to activate the classical complement pathway by direct interaction with the first component of complement, C1, without the intervention of antibody. No evidence was found for activation of the alternative pathway. Following classical pathway activation the specific affinity of EBV for B cells can be presumed to be lost since the virus will become opsonized for clearance by phagocytic cells bearing complement receptors, CR1 and CR3. This activation is further evidence that complement plays a role in defence mechanisms independently of antibody activity.
