Abstract

The 4-day response of C3H/HeJ mice to sheep erythrocytes was suppressed by a lipid-free teichoic acid with an average molecular weight of 2,900 when it was administered by the intraperitoneal route. Enhancement was not observed at that time, and neither suppression nor enhancement could be demonstrated by the intravenous route. Either suppression or enhancement of background plaques could be induced, depending upon the timing. Dosage influenced the degree of suppression from 8 to 100 micrograms, whereas suppression of background plaques required only 1 microgram of lipid-free teichoic acid. The kinetics of the sheep erythrocyte response was altered by treatment of the mice with lipid-free teichoic acid, delaying the peak until day 5 and producing enhancement at that time. Although lipid-free teichoic acid was shown to be toxic for mouse splenocytes (50% lethal dose, ca. 200 micrograms) in vitro, no effect at the levels employed was observed in vivo. The data presented indicate that modulatory activity is influenced by route, timing, dosage, and apparently the number of antibody-secreting cells.
