Statistical analysis
All data represent the mean value ± SD from a minimum of five independent experiments with at least five healthy donor HPBLs samples, and each experiment was repeated more than three times. The statistical differences of values were calculated using ANOVA-analysis. Differences between groups were considered significant at p <0.05;p <0.01; p <0.005 andp <0.001; p- values were calculated with a Chi-square test.
