cholera toxin subunit b which binds cell surface ganglioside galactosyl-n-acetylgalactosaminyl - [ n-acetylneuraminyl ] - galactosylglucosylceramide ( gm1 ) without activating adenyl cyclase had no effect either on natural cytolysis or on the enhancement of natural cytolysis by interferon , suggesting that mere binding of cholera toxin to the cellular receptor was not enough to inhibit natural cell-mediated cytolysis .
