The ΔlamA ΔlamR mutant induced significantly higher IL-10/IL-12 ratios check details (adj. p value < 0.001) and IL-10 (adj. p value < 0.001) amounts in PBMCs (Table 3). These effects were partially dependent on the growth-phase of the L. plantarum cells. IL-10/IL-12 ratios and IL-10 amounts induced by wild-type and mutant cells were significantly different when exponential phase cultures were used in the PBMC assay, whereas IL-10 and IL-12 amounts also differed when stationary-phase cells

were examined (Figure 2, 3, 4 and Table 3). Figure 4 Boxplots of IL-10/IL-12 amounts produced by PBMCs in response to L. plantarum 4EGI-1 purchase wild-type and mutant cells. 2Log transformed IL-10/IL -12 ratios induced by exponential and stationary phase L. plantarum cells are shown. The dots indicate the median value, the boxes indicate first

and third quartile, and the whiskers extend to outlying data points for a total of 12 measurements (3 PBMC donors were measured using 4 replicate cultures of each L. plantarum strain).

Selleck Gemcitabine plantarum cells were harvested (log = exponential phase; stat = stationary phase). c The value is the average difference in 2Log cytokine amounts induced by wild-type L. plantarum and mutant cells harvested in the same phase of growth (log or stat). A positive value indicates an increase in IL-10 levels produced by PBMCs in response to mutant L. plantarum compared to the wild-type cells.
