title: Effect of lipopolysaccharide on the development of cell-mediated immunity to transplantation antigens.
abstract: Lipopolysaccharide (LPS) from Escherichia coli administered to allografted mice in a single dose of 20 microgram influenced the development of cell-mediated immunity to skin donor antigens. As an indicator of cell-mediated immunity, donor antigen-induced inhibition of cell migration from spleen explants of allografted animals was used. Cultures of spleen explants were established 16 days after grafting. The antigen-specific inhibition of migration was abolished when LPS was injected either 4 to 2 days before grafting and intensified when LPS was administered on the 2nd day after grafting.
