Abstract
To isolate antipruritic lactic acid bacteria (LAB) from kimchi, a traditional Korean food, we investigated the interleukin (IL)-4 production-inhibitory effect in the colon of mice for previously isolated LAB. Orally administered Lactobacillus plantarum PM008 potently inhibited the expression of IgE-switching cytokine, IL-4, and of proinflammatory cytokines, IL-1β and TNF-α, in the colon of mice. Its inhibitory effect was dependent on the dosage and administration period. When PM008 was orally administered to mice, the number of PM008 detected in the intestine and feces by polymerase chain reaction (PCR) and fluorescence in situ hybridization (FISH) methods was dependent on the administration dosage and period. The number of PM008 attached in the intestine was gradually decreased with increasing time after completion of its oral administration. PM008 dose-dependently inhibited the scratching behavior induced by histamine or compound 48/80. PM008 treated at a dose of 1 × 10(10) CFU for 14 days inhibited the histamine- and compound 48/80-induced scratching behaviors by 32.8% and 48.6%, respectively. This inhibitory effect continued, although reduced, at 7 days after stopping the oral administration of PM008 attached in the intestine. Based on these findings, L. plantarum PM008 may improve pruritus by inhibiting IL-4 expression.
