MeSH definition : Multinucleated masses produced by the fusion of many cells; often associated with
viral infections. In AIDS, they are induced when the envelope glycoprotein of the
HIV virus binds to the CD4 antigen of uninfected neighboring T4 cells. The resulting
syncytium leads to cell death and thus may account for the cytopathic effect of the
virus.;
