title: Steroidal glycolipid, L-644,257, is a potent enhancer of nonspecific host resistance.
abstract: A steroidal glycolipid that enhances the nonspecific cellular response to opportunistic infection in an immunocompromised host has been discovered. A dose dependent response with 6-(5-cholesten-3 beta-yloxy)hexyl 1-thio-beta-D-mannopyranoside, L-644,257, was observed against several infective agents including bacterial, fungal, and viral pathogens in cyclophosphamide-treated mice. A mechanism for this protective action is proposed.
