    Abstract:
    Bovine erythrocyte sialoglycoprotein (GP-2) (1) containing lactoseries oligosaccharide chains, which showed highly specific inhibition of hemagglutination by HVJ (Hemagglutinating virus of Japan, Sendai virus), was incorporated into neuraminidase-treated chicken erythrocytes which had lost their biological responsiveness to the virus. The GP-2-incorporated erythrocytes were agglutinated and lyzed again by the virus. Incorporation of 1,900 molecules of GP-2 per asialoerythrocyte restored fairly well the susceptibility of the cells to HVJ-mediated agglutination and hemolysis. Treatment of the erythrocytes with neuraminidase again resulted in the complete abolishment of the response to HVJ. The above observations are consistent with the view that exogenous sialoglycoprotein, GP-2, can be functionally integrated into the surface membrane of asialoerythrocytes and serve as the receptor for HVJ during the initial adsorption-fusion phase of the virus infection of the target cells.
