Abstract
|
|
|
The objective of this study was to investigate the immunomodulatory effects mixed with Weissella cibaria JW15 strain and black soybean (Glycine max (L.) Merr.). In this experiment, JW15 was cultured in De Man Rogosa and Sharpe (MRS) broth at 37% for 17 hr, and the cells were washed twice with sterile phosphate buffered saline (PBS) (pH 7.2). And black
soybean was extracted by ethanol or hot boiling water. The immuno-modulatory effects of mixed JW15 and black soybean extract were investigated by measuring the production of nitric oxide (NO), nuclear factor κB (NF-κB) and cytokine (Interleukin-1β and Tumor necrosis factor-α) in RAW 264.7 macrophage cells or RAW blue cells. The 0.1 % ethanol and hot water extract of black soybean increased NO, NF-κB, and cytokine production in a concentration dependent manner.
The NF-κB activation by JW15 mixed with 0.1 % hot water extract of black soybean (0.26 ± 0.02) was significantly higher than JW15 alone (0.20 ± 0.02). Also, combination of JW15 and 0.1% hot water extract of black soybean triggered IL-1β production of 110.19 ± 4.38 pg/mL, which was significantly greater than the JW15 alone (12.06 ± 7.58 pg/mL). The results of this study indicate that combination of Weissella cibaria JW15 and black soybean extract may have an ability
to activate innate immune response synergistically. According to these results, the mixture of JW15 and black soybean extract could hold great promise for use in probiotics.
