    Abstract:
    Specific gangliosides GD1a, GT1b and GQ1b isolated from brain have been shown to function as receptors for Sendai virus by conferring susceptibility to infection when they are incorporated into receptor-deficient cells (Markwell, M.A.K., Svennerholm, L. and Paulson, J.C. (1981) Proc. Natl. Acad. Sci. USA 78, 5406-5410). The endogenous gangliosides of three commonly used hosts for Sendai virus: MDBK, HeLa, and MDCK cells were analyzed to determine the amount and type of receptor gangliosides present. In all three cell lines, GM3 was the major ganglioside component. The presence of GM1, GD1a and the more complex homologs of the gangliotetraose series was also established. In cell lines derived from normal tissue, MDBK and MDCK cells, gangliosides contributed 47-65% of the total sialic acid. In HeLa cells, gangliosides contributed substantially less (17% of the total sialic acid). The ganglioside content of each cell line was shown not to be immutable but instead to depend on the state of differentiation, passage number, and surface the cells were grown on. Thus, the ganglioside concentration of undifferentiated MDCK cells was found to be substantially greater than that of MDBK or HeLa cells, but decreased as the MDCK cells underwent differentiation. Changes in culture conditions that were shown to decrease the receptor ganglioside content of the cells resulted in a corresponding decrease in susceptibility to infection. The endogenous oligosialogangliosides present in susceptible host cells were shown to function as receptors for Sendai virus.
