Abstract

Lipopolysaccharide (LPS) obtained from Porphyromonas gingivalis was found to exhibit marked lethal toxicity in galactosamine-sensitized C3H/HeJ mice. Although no lethality was observed in mice intraperitoneally challenged with 1 mg of P. gingivalis LPS without galactosamine, when they were sensitized with 30 mg of galactosamine, challenge with 1 and 10 micrograms of LPS resulted in 67 and 100% lethality, respectively. The lethal dose of LPS was almost the same in LPS-responsive C57BL/6 mice and non-LPS-responsive C3H/HeJ mice. Furthermore, when 1 microgram of P. gingivalis LPS was administered to each mouse 90 min before the challenge with the same LPS with galactosamine, tolerance to the lethal action of LPS was induced, and the mice were completely protected from death, even at a dose 100-fold greater than the lethal dose of LPS. Neither a lethal effect nor induction of tolerance to the lethality of P. gingivalis LPS was exhibited by Salmonella LPS in galactosamine-sensitized C3H/HeJ mice. A protein-LPS complex derived from Pseudomonas aeruginosa, which exhibited strong lethality and induced tolerance to a subsequent challenge with a lethal dose of LPS in galactosamine-sensitized LPS-responsive mice, did not exhibit lethal toxicity in galactosamine-sensitized C3H/HeJ mice and failed to induce tolerance in these mice to the lethality of P. gingivalis LPS. These results indicate that P. gingivalis LPS plays the central role in the activation of non-LPS-responsive C3H/HeJ mice.
